That Fish Blog – Aquarium Advice and Information

Hello again everyone! Craig here again, and in my last blog I talked about some of the biggest of the freshwater fish to be kept in home aquariums. In this blog, I will go over some of the big saltwater fish found in the hobby. Without a doubt, there are very large fish that call the sea their home. Some of these mammoth fish are being kept by hobbyists. With all the challenges of keeping a marine tank in tip-top condition, adding a giant fish to the mix can present dedicated fish keepers some challenges.

Large fish can be intimidating not only for their size, but their ferocious looks, too. Moray Eels are certainly some of the most intimidating. Their snake-like bodies and gaping mouths often cause people to get squeamish. One species, Gymnothorax favagineus, the Honeycomb Moray, is one of the most beautiful. Also known as the Tessellated Moray, this is one impressive fish. Able to reach a size of over 6 feet in length in the wild, this is definitely a giant. Boasting a beautiful white body with black splotches, there are few morays that are as attractive. In some individuals the dorsal takes on a yellow hue.  Read More »

Footprint

This is more than just the actual size of the aquarium. Obviously, a 180 gallon tank would make a poor desktop aquarium just as a 10 gallon tank would be an inadequate room divider. Measurements aside, it is important to also consider how much weight the floor can support, particularly if you’re considering a large tank on any floor with open space beneath. In the 19^th century house I live in, I’m fairly certain that a large tank would go straight through the floor and end up in the basement. Some apartment complexes won’t even allow larger aquariums, especially on upper stories. A gallon of water weighs a little over 8 lbs, so water weight in addition to substrate and ornamentation can spell disaster on a weak floor. Saltwater aquariums are also generally going to be heavier than freshwater aquariums – the salt in the water and live rock used in most tanks increases the weight. Read More »

Some of the most interesting animals in aquariums can be the ones we never knew we had.  Aquarists often turn to the internet in trying to figure out what some unidentified thing in their aquarium is and where it came from. One of my favorite unexpected hitchhikers is the Stomatella Snail.

Stomatella Snails look like and are often mistaken for several other organisms like Limpets, Nudibranchs (sea slugs), or Abalone Snails but they are actually more closely related to Turbo and Margarita Snails. Stomatella’s only grow to just over an inch in length and have a small, flat shell on the top of their body. They actually don’t fully withdraw into their shell like other more traditional snails. This external shell and small operculum (the “trapdoor”) on the back of their foot separate them from the Nudibranchs and sea slugs, and the lack of “holes” and openings in the shell separate them from the Limpets and Abalones.

Within the aquarium hobby there are many niches. There are reef geeks and coral collectors, catfish aficionados and people that think that guppies are the best thing ever. There are also those in the hobby that will give anything, and pay any price, to keep the biggest and baddest fish possible. Everyone loves an impressive fish that screams “Look at me!” But how realistic is it for the casual aquarist to keep a big fish? Well, that depends on the fish really.  Let’s take a look at some of the more commonly kept aquarium giants. Read More »

Green water. Nuisance algaes. Cyanobacteria. Poor coral growth. Random invertebrate death. All of these are problems found in freshwater aquarium, ponds and saltwater aquariums and leave many aquarists stumped. Most of them can be diagnosed with one simple water test however – the often-overlooked Phosphate test.

What is a Phosphate and Why Should I Be Concerned?

Phosphate is a naturally occurring compound with several sources in aquariums and ponds. The most common may be the source water used. Some municipalities and well water sources naturally contain phosphates. It can come from the soil in the area or from run-off into the water sources, especially in agricultural areas or areas that use a lot of fertilizer (phosphate is one of the main ingredients in fertilizers used on farms and backyards alike). While the levels may not be considered dangerous or high to humans, it can accumulate in aquariums. Phosphates can also enter an aquarium through the salt mixes used in saltwater aquariums, in the rocks and decorations used, and in the thawed water from commercial frozen foods. Read More »
