That Fish Blog – Aquarium Advice and Information

The beauty of a thriving planted aquarium is undeniable; it is like an exotic slice of nature in your living room.  Many people shy away from advancing to a live planted aquarium because they think it is too difficult.  Some folks have tried, and failed, and decided that live plants are not for them.  Whatever the cause for not keeping live plants may be, the truth is that keeping live plants can be easy with a little guidance to help your chances of success.  There are a wide variety of easy to keep aquarium plants available, here are my top ten.  I have separated these into two groups, with smaller plants listed as foreground plants, which are also well suited for shorter aquariums.  The second group is for mid-ground and background plants, which will work well, planted behind foreground plants, and can be incorporated into taller aquariums.

 

Foreground Aquarium Plants

 

Java Moss (Vesicularia dubyana) is fairly undemanding. It can be left floating or attached to a surface like wood or rockwork (anchor in place with fishing line or another tie and remove the ties when plant has attached). It will form mats that provide hiding places for inverts and fish fry as well as a low foreground texture to the aquarium.   Java Moss will thrive in low light aquariums, and requires no special care.

 

 

Moss Balls (Chladophora aegogrophila) Moss Balls are a truly unique addition to planted aquariums. They are non-invasive structures that are actually made from algae shaped by wave action. Moss Balls are low maintenance, tolerating a wide range of water conditions and tolerant of minimal lighting (though they thrive better in moderate lighting). They may be left in their ball shape or split and attached to a surface like driftwood or rockwork (use fishing line or another anchor until attached, then remove the ties).

 

Anubias Nana (Anubias barteri ‘nana’)  There are several forms of Anubias Barteri, that have been developed for aquarium use, with Anubias Nana being the most common.  Anubias plants are characterized by their broad, thick, dark green leaves.  Anubias Nana is an extremely tough plant, which can be kept with fish that may eat other more delicate species.  This plant will thrive in low to medium light aquariums, and a wide range of water conditions.

 

Narrowleaf Chain Sword (Echinodorus tenellus)   Also known as Pygmy Chain Sword, this grasslike plant is one of the smallest of the sword family, and is an excellent choice as a foreground plant, or for small aquariums.  Narrowleaf Chain Sword is tolerant of a wide range of water conditions, but requires moderate to high lighting to maintain its small size.

 

 

Micro Sword – (Lilaeopsis brasiliensis) Micro Sword is another excellent foreground plant, and is a staple for aquatic gardeners of all levels.  This plant forms dense green mats, which resemble a green carpet across the bottom of the aquarium.  Tolerant of a wide range of water conditions, this plant is a fast grower, but requires strong lighting to keep a short dense appearance.

 

 

 

Mid-ground and Background Aquarium Plants

 

Amazon Sword (Echinodorus bleheri) The Amazon Sword is one of the most iconic aquarium plants used in the hobby, and is probably what most people visualize when they think about aquarium plants.  These plants are tolerant of a wide range of water conditions, and can grow quite large.  These plants can also survive in low to medium light, but will thrive in medium to high light levels.  Be careful not to plant smaller species close to this plant, as it will overshadow smaller plants in a short amount of time.

 

Java Fern (Microsorum pteropus) Java Fern is a hardy plant that tolerates a wide range of conditions. They can tolerate lower lighting as well as the higher pH and hard water of cichlid aquariums and aquariums with higher lighting. They even may be used in brackish water aquariums with low salinity.  Java Fern can easily be attached to driftwood and rockwork, and can form a dense covering on these structures if allowed.  Mature plants can grow leaves up to a foot in length.

 

Cryptocoryne (Cryptocoryne wendtii) Cryptocoryne wendtii is one of the most popular of the Cryptocoryne plants, which are commonly called Crypts. They are adaptable to most aquarium conditions, although the conditions in which it lives will often affect its form. When grown in lower light, the plant will become taller and narrower.  Crypts grown in higher light will typically remain more compact with broader leaves. The color also varies greatly. Some of the most popular variations in the aquarium trade are green, red and bronze.

 

Anubias Congensis ( Anubias barteri ‘congensis’) Anubias Congensis is another form developed for aquariums from Anubias barteri plant.   Congensis has dark green, waxy, spear-shaped leaves which grow to an average height of about 15 inches.  Like most of the Anubias aquarium plants, this variation is adaptable to a wide range of aquarium conditions, and thrives in low to medium light levels.

 

 

Sagittaria (Sagittaria subulata) Subulata is a thin, grasslike plant. The leaves are green in coloration with some areas of reddish brown. A “dwarf” variant is often available as well as the “regular” Subulata but height is often dependent on lighting; the plants will grow taller in lower lighting but will stay more compact and spread laterally in higher lighting. Subulata will thrive in a wide range of water and light conditions, and may tolerate brackish water environments with very low salinity.

 

 

If you have ever considered trying a freshwater planted tank, but did not know where to start, give some of these plants a try.  Once you see how easy it can be, the sky is the limit, and you are on your way to becoming an aquatic gardener.

Florida has stepped up its game in recent months, in an effort to combat their serious problem with invasive lionfish.  Some of which has a direct impact on the aquarium hobby in the state of Florida.  In what seems like a very short amount of time, the problem has gone from rumors and possible sightings, to a full out invasion.  Lionfish populations have exploded and now are affecting the entire state of Florida, and neighboring areas of the Caribbean, Gulf of Mexico and The U.S. East Coast.

This story has been one of particular interest for us here at That Fish Blog, and we have covered the topic in detail in past entries from 2007, 2008 ,2010  again in 2013

 

It has only taken about 30 years for these predators to establish themselves, and spread like wildfire.

In a unanimous vote by the commissioners of the Florida Fish and Wildlife Conservation Commission, the State has adopted several measures to help fight against the invasive fish.

1. Complete import ban of all Pterios genus Lionfish into the state of Florida.  No more mail order lionfish, and no more imported lionfish in Florida pet stores.
2. Divers are authorized to use rebreathers, in the capture and harvest of Lionfish.  This enables divers to dive longer, deeper and quieter while hunting lionfish.  Use of rebreathers is otherwise prohibited for spear fishing in Florida.
3. Authorizes the Executive Director to issue permits for spear fishing tournament in waters that would otherwise be off limits to spear fishing.

These new regulations will go into Effect on Aug 1, 2014.  Already in place in the state of Florida are regulations that promote and encourage fisherman to hunt and remove Lionfish, which is the only viable option for hoping to control their growth.  There are no minimum size limits, closed seasons or bag limits for recreational or commercial harvest, and a recreational fishing license is not required to harvest lionfish when using dip nets, pole spears, Hawaiian slings or any spearing device designed and marketed exclusively for lionfish.

Reporting Lionfish sightings is now easier than ever, there is an app for that!  Anglers can report lionfish sightings by downloading the new Report Florida Lionfish app on a smart device or by visiting MyFWC.com/Fishing and clicking on “Recreational Regulations” (under “Saltwater”) and then “Lionfish.”

Try a new adventure, and get involved with efforts to remove lionfish.  Fishing Tournaments, charter fishing, or just recreational fishing is both fun and can serve a good purpose as well.

Finding the perfect new addition to an aquarium is often like finding the Holy Grail to many aquarists. We all want the perfect little helper to keep the tank clean so there’s less work for us to do (and so our tank is cleaner and healthier, of course) but many “algae eaters” get too large for smaller aquariums and many others like the group of fish known as “plecos” don’t even eat algae at all. So what are the best plecos and algae eaters for small freshwater aquariums? Here are a few of our favorites that are some of the best choices for smaller community aquariums:

 

Bushynose & Bristlenose Plecos (genus Ancistrus)

• PROS: Lots of variety in color and pattern, small size, vegetation-heavy diet (including algae), community-friendly.
• CONS: Some species grow larger than others, needs meaty foods as well, underfed fish may eat live plants.
• BEST SUITED AS: A community algae-eater and bottom-feeder.

 

Plecos from the genus Ancistrus usually have “Bristlenose” or “Bushynose” somewhere in their common names, a nickname that comes from the whisker-like frills that develop on most adults. They are usually more prominent in adult males but some females may get them too in some species. Different species in this group have different requirements, but they are generally among the smallest plecos. While they eat some meatier foods as well, most appear to eat mostly vegetation.

 

 

Clown Pleco (Panaque maccus L104)

• PROS: Small size, easy-going temperament, fairly wide-spread diet.
• CONS: Need driftwood for grazing, not primarily an algae-eater.
• BEST SUITED AS: A general clean-up bottom-feeder for community aquariums.

The Clown Pleco is a popular small pleco. As with other Panaque plecos, these fish are omnivores and feed about equally on plants matter and meatier foods. Panaque plecos are also unique in that they actually feed on driftwood as well; make sure you have driftwood décor in your tank for these fish to graze on.

 

 

 

Hillstream Loaches

• PROS: Eats algae, can be kept in groups, unique and unusual appearance.
• CONS: Needs high flow and pristine water, vulnerable to aggressive tankmates and poor water chemistry.
• BEST SUITED AS: A unique addition to a suitable community aquarium where it incidentally may help eat algae but isn’t the primary algae-eater.

Hillstream Loaches have flattened guitar-shaped bodies and are often mistaken for plecos. They cling to rocks in the fast-moving mountain stream where they come from much like plecos cling to surfaces. Hillstream Loaches need well-oxygenated and well-filtered tanks and don’t do well with nippy tankmates or in tank with less-than-pristine water quality. They do eat some algae however, as well as other detritus and leftover sinking foods.

 

 

Otocinclus Catfish

• PROS: Small size, safe for planted tanks, primarily algae-eaters.
• CONS: Can be sensitive to stress, can starve if they can’t find enough to eat.
• BEST SUITED AS: Algae-eating housekeepers in planted community aquariums.

 

There are a few very similar species that are commonly grouped together as Otocinclus Catfish (“Oto Cats”) or “Dwarf Suckermouth Catfish”. Most are brownish-grey in color with a black stripe but some like the Zebra Oto (Otocinclus cocama) have a more ornate pattern. These fish stay under two inches in length and are great for eating algae off of plants without harming the plants. They can be a bit finicky and sensitive though so only keep in a stable, healthy aquarium. They are also best kept in groups so plan tankspace accordingly.

 

 

Rubbernose Plecos (Chaetostoma sp.)

• PROS: Moderately small adult size, eats some algae, community temperament.
• CONS: Not a primary algae-eater, can be bulky for very small tanks.
• BEST SUITED AS: A general bottom-feeder for community tanks over about 30-45 gallons.

 

Like the Clown Pleco, Rubbernose Plecos are some of the most common smaller plecos available. They also have a very familiar pleco-like appearance that many novice aquarists associate with algae control. They are not exclusive algae-eaters however; this is another omnivore that needs about equal parts meaty food and plant matter. These fish are pretty middle-of-the-road overall: moderate adult sizes, eats diet for about half their diet, neutral coloration, moderate temperament.

 

 

Freshwater Nerite Snails

• PROS: Colorful shells, safe for plants, small size.
• CONS: Limited availability, may reproduce, may be vulnerable to predators.
• BEST SUITED AS: Algae-eating grazers for small planted aquariums.

 

Nerite Snails are popular for saltwater aquariums but some species are found in freshwater as well. These snails are much smaller than some of the other less-suitable and more invasive freshwater snails like Apple Snails or Trapdoor Snails. They mainly eat smaller algaes like the ones that cause spots on glass but usually won’t harm plants. These snails also appear to bred less frequently in most aquariums than the more common Apple Snails. Make sure the ones you get are from freshwater; a saltwater Nerite will not survive being moved to a freshwater tank.

 

Freshwater Shrimp (Caridina sp.)

• PROS: Safe for plants, small size, can be kept in groups.
• CONS: Limited availability, vulnerable to predators, very small.
• BEST SUITED AS: Algae-eaters for planted nano tanks with peaceful or no other tankmates.

Small freshwater shrimp like the popular Cherry Shrimp and Amano Shrimp can be ideal grazers, especially for nano tanks (under 1-2 gallons). Some are clear, some are colored or have colored markings and they can be kept in groups. However, most of these shrimp are very small; you may not see them often and can’t be kept with anything remotely predatory.      

 

 

 

As always, the best algae-eater for your tank depends on its tankmates, the size of the tank, the water parameters and other such factors but hopefully this helps give you some alternatives to fish that may be too big or otherwise unsuitable to your needs. If you need more help in making your best choice or have a favorite of your own, feel free to comment below!

A few years ago our plant suppliers introduced new items for sale that were just too fun and interesting to pass up. They were simply called moss balls. If ever there was an aquarium plant with personality, this would be it. They have a certain character, and can almost become like a pet in the aquarium even if they aren’t dazzlingly colored or active like the fish we keep. The vague nomenclature was accurate enough, but the story of where and how these mysterious moss balls come to be is as interesting as they are to look at when you place them in your aquarium.

Marimo, Japanese for “ball seaweed”, were named by a Japanese botanist decades after they were originally described by someone else in Austria around 1820. They originated in shallow areas of a few freshwater lakes in the world including several in Japan, Iceland, Scotland and others. In the trade they are referred to as moss balls or Japanese moss balls, but they also have several other names given by those who encounter them in their native waters. The name seems fitting…each ball has a velvety, thick, fuzzy texture much like a mound of filamented moss. However, moss balls aren’t really moss at all. These unique formations are actually colonies of the filamentous algae Aegagropila. They were previously classified as Cladophora aegagropila, but modern research proved that they actually belong in genus Aegagropila. Don’t let their classification as algae scare you, this is a fun, non-invasive kind! Read More »

For all of those who love Banded Coral Shrimp, Peppermint Shrimp, and Arrow Crabs along with all of the other fish and invertebrates found in the Caribbean, we have some great news! Last week we received our first full shipment of livestock since the earthquake in Haiti. Even better news is the availability and prices are about the same as they were before the disaster. There are still a couple of fish such as the Black Cap Basslet that are still unavailable, but they are few and far between. Read More »
