Growing Green – Live Mosses for Aquariums

Java MossI love a green aquarium…not green in the algae-covered, pea soup kind of way, but green as in dense with varying colors and textures of aquatic plants. We all know that there are many types of aquarium plants, from slow growing Anubias to massive Echinodorus, but one of the often overlooked groups is the mosses. These colonies of simple, prehistoric plants have a special niche in the aquarium when it comes to aquascaping, and they’re also really useful to many types of fish. Here’s a little primer on common mosses for aquariums and what they can bring to your tank.

About Mosses

Mosses aren’t like other plants. They’re simpler in structure, lacking roots and the thick vascular leaves of true plants. These plants don’t blossom or produce seeds.  Most mosses reproduce with spores, relying on moisture to fertilize and create the next generation. Aquatic mosses simply spread, creating new plants with their existing vegetation, so a small portion can populate a vast area. Simply place or anchor small bits or strands where you want them to grow and, under the right conditions, you’ll have lush mounds in just a few short weeks.  Read More »

My Experience with the Red-breast Acara, Laetacara dorsigera

Hi, Jose here. When I was younger, I was looking for something that would light up the bottom of my 30 gallon South American tank. I did a little research and found a picture of a curviceps…I got really excited because from what I found they were pretty little fish. I purchased a trio of Dwarf Acara at a local pet shop labeled “sky blue curviceps”.  I didn’t know much about them, and I hadn’t really heard about them from other enthusiasts, but then again I wasn’t into cichlids at that time, so it was something new.

After they became adjusted to the tank, I ran peat through my Fluval 402 filter and hoped for some eggs. After a couple of nerve wrecking months, I noticed that a pair had formed and the third fish was killed by the pair. I placed some smooth, flat 5 to 6 inch rocks hoping the new couple would spawn on one. I figured that their tankmates (neon tetras) wouldn’t mess with the eggs, so I didn’t have to worry about anything eating them. But in watching the pair, I noticed something that worried me a little. I thought the male would be a light blue dwarf, but this fish was developed red color from the lower tip of the mouth to the rear of the body and red ventral fins. The “female” was also brightly colored, so I started wondering if I had two males. The person at the pet shop told me the female should be dull-looking because only males have color, a common trait amongst many cichlid species.  Read More »

Keeping Tropical Fish in Outdoor Ponds – Dangers and Preparing for the End of the Summer Season

Ornamental PondHi, Jose here. Last time, I blogged about keeping tropicals outside and how the sunlight, natural foods and warm temperatures can benefit tropical species. While the benefits are great, there are also some cautions to consider. This time I’d like to talk about some of the dangers and pests that may wreak havoc on our poor little fishies.

I was lucky not to have my pond visited by pests, but local stray cats, opossums, raccoons, snakes or predatory birds that may decide to visit your pond at any time.  Even bugs like dragonfly nymphs can prey on young and small fish. Ample water movement and surface ripples are usually enough to deter them, but more effort may be needed to deter larger predators. There are some easy ways that you can help to protect your fish while they enjoy their outdoor summer vacation. Personally, I would recommend the live plants. You can use floating foliage like water lilies, duck weed or hyacinths for cover and protection for your fish. Young fish will also hide in the roots and feed on the small bugs that live in the roots. Another solution is the use of pond netting. The netting can prevent many predators from snatching your fish out of the water. Not very aesthetic, but effective. Read More »

Spawning Fish in the Aquarium – Raising Fry

Baby AcaraIf you have a healthy, well-established aquarium and happy fish, there is a good possibility that you may be blessed with batches of eggs or baby fish from time to time.  A common question our customers pose is “What do I have to do for them?” That’s a question that can have several different answers. As with most things aquarium, the first things to consider are your set up and the fish in concern.

Nature’s Course

The most passive answer is “do nothing”. It may not be the answer you want to hear, but depending on your situation, it may be the best one. Some fish are naturally attentive parents. They may actively defend and even nurture the fry their brood. As long as the threats within the tank are minimal (few if any predators, low flow, ect.) and the small fish have plenty of cover, they will have a chance.  A few of of the offspring may survive to maturity, but most will disappear, just as it happens in the wild.

Aquariums in Classrooms as Educational Tools

Crayfish in aquariumSchool isn’t always the most stimulating place for kids to be all day, but as I remember, there were some things that made long days much more interesting and bearable. Visual aids and interactive tools, to me anyway, could reinvigorate my zest for learning. The most interesting and anticipated place in my school was the science wing. Those rooms were always full of the most interesting things to look at–specimen jars filled with preserved animals, reassembled skeletons, and of course, live displays. Having tools like these in the classroom for hands-on experience and to break the monotony of repetitive days is something that, for some students, may instill more passion, curiosity and interest to increase their scholastic performance.

With a little money, know-how and effort, simple aquarium set-ups in a school or classroom can become invaluable tools as well as enhancing the sometimes sterile aesthetic.

Benefits of Institutional Displays

The most obvious benefit of having live displays in classrooms is the offering of “hands-on” education.  It can be any kind of set-up…freshwater, saltwater or reef, or even a reptile, amphibian habitat. Each unique set-up can provide relevant topics and visual aids for biology, anatomy, chemistry, ecology and physics courses. Not every kid in the class may have the opportunity or means to see aquariums up close. You can provide a platform for such students to “see” the nitrogen cycle in action, witness the process and stages of fish reproduction an development, or maybe chronicle predator/prey, symbiotic, or other co-habitation relationships between the organisms in the display.  And that’s only the beginning!

These live and variable habitats can be great for developing critical thinking and problem solving skills. What caused a fish to spawn? Why do fish school together? Why did a fish get sick or die when the others seem healthy?

Aquariums can be beneficial in non-educational ways to students and faculty as well. Peering into the serene aquatic environment can ease stress and calm spectators. Tests, deadlines and other pressure points can influence a child’s ability to focus…an aquarium can help to alleviate this tension for some.  This is one reason why you often find aquariums in dental and medical offices. too.

Aesthetically, a well-maintained aquarium can enhance any environment. Whether in an individual classroom or a lobby or hallway, any live habitat is sure to draw attention and smiles. Worried about the responsibility of keeping the tank maintained?  Why not consider an extra-curricular club or group to help with the work?  Interested students or other faculty members can gain even more experience for an hour or so a week. Water changes, filter maintenance and other duties don’t have to be work, they can be continuing education!  

More Than Just Science

Colostethus panamensis in AquariumAquariums and other live displays are of value to more than biology and chemistry. These set-ups can be inspiring! Think of applications other educators can use–reading/research and writing topics on aquariums can be endless, encouraging good writing, grammar, and research skills. Factual reports and journals aside, a nice aquarium set-up and some colorful fish can inspire kids of any age to create art and creative writing stories, too. They can even be tools for math, applying formulas to find out volume, dosing amounts of supplements or medications, and much more. Imagine the classroom discussions and problem solving skills that can be developed using such a tool…the possibilities are endless.

Getting Started

A classroom set-up may seem intimidating or overwhelming to a teacher who has never had experience with aquariums or animals before, but it doesn’t have to be. You’ll just need some basic essentials and a basic knowledge of what to expect to get started. There are even kits available that are almost out-of-the-box ready. Pet store staffers and hobbyist forums can help you with any questions or problems you may run into. Habitat kits are also available for reptiles and small animals which can also be great additions to a teaching curriculum.

Continuing Education at Home

Freshwater AquariumRemember when it was your turn to bring the class pet home for the weekend?  Whether or not you personally had that opportunity or you know a child who has, you can recall the excitement of the experience. It may have been one of the things that got you into the aquarium hobby to begin with. Maintaining aquariums and other live animal habitats provide kids of any age not only with practical education, but it also helps them to develop a sense of responsibility and pride. Parents may find that an aquarium is a great way to keep kids motivated and interested in learning while also increasing emotional bonds, and maybe even life experience to some degree, over a common activity or project.

Keep in mind, it doesn’t have to be complicated.  A betta bowl, a hamster…something small and easy to care for. Plant the seed early, nurture it, and chances are the interest will grow as the child does, along with the thirst to know more.  If you can’t do it at home, encourage your child’s teachers or contribute funds and materials towards live displays in your local school for this year and generations to come.
