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.

Dangers of Ciguatera Poisoning

Moray Eel“This fish has been known to cause ciguatera poisoning.”

Have you ever seen this warning on books, magazines or other media? It can apply to a few hundred tropical and subtropical reef fish (possibly over 400 according to some references) including some very popular aquarium species. You may even have some of these fish in your aquarium right now.

If you have no idea what ciguatera poisoning is, you aren’t alone. Even some TFP employees that I mentioned this blog topic to had no idea what “ciguatera poisoning” was even though they have seen the term before and we deal with these fish every day. Is it something that, as aquarists, should be worried about? No….and yes. Ciguatera poisoning is food-borne. As long as you don’t make a regular habit of eating fish from your aquarium, you aren’t going to contract it at home. But, if you eat fish regularly, it may a concern and certainly deserves more awareness than it is given. Read More »

Ecoxotic Cannon LED Pendant Fixture Put to Work At That Fish Place – That Pet Place

Cannon fixtureWe recently upgraded the lighting on our large cylinder display tank in our Lancaster, PA retail store.  Out with the old technology and in with the new.  We said good-bye to the power hungry,  ceiling mounted, heat producing 400W Metal Halide fixture, and installed a sleek, energy efficient, high output 50W LED Cannon LED pendant light — WOW what a difference!  The compact size of the Ecoxotic Cannon does not distract from the display and it provides incredible brightness and shimmering light into the aquarium.

The Ecoxotic 50 Watt Cannon Pendant uses state of the art Multi-Chip LED technology, which allows incredible lumen output in a small package.  Even though the light is only 50 Watts, the Cannon pendant easily illuminates this four foot deep, four foot diameter acrylic cylinder . These fixtures are also incredibly energy efficient, which can lead to big savings over time.

Cannon fixtureWith the help of our friend Ike at Ecoxotic, we chose the 12,000K 50 Watt Cannon for this aquarium, but Ecoxotic has several other options to choose from.  Also available in the 50 Watt model is a 453nm actinic blue pendant. The 50 Watt versions have built in drivers, and are ready to be wired out of the box.  For those of you who need more light output for a serious display or coral farm, Ecoxotic also makes an even more powerful 100W version of the cannon, also available in 12000K and 453nm blue. The 100 Watt cannons use a remote driver (sold separately), swivel bracket mount and standard and dimmable versions are available.  Don’t let the 50 and 100 Watt ratings fool you, these are really powerful lights not intended for nano tanks and other smaller set-ups.

If you visit the store, check the new fixture out for yourself to see the amazing effect it has on the display.

Thanks,

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.

Fish and Floods – How Raging Waters can Benefit Fish

Swat River floodedAnyone who has ever experienced a flood first hand will have very few (if any) positive things to say about the disaster after the water recedes. Recent flooding in the northeast left thousands to bucket mud and sediment from their homes and some lost their homes entirely. Floods for us are rarely a benefit, but for fish and waterways, flooding performs vital work. Despite the unfortunate individuals that find themselves stranded in backwater pools and puddles (most of which are picked off by advantageous predators), the fish that remain or find their way nack to an adequate stream or river can thrive after these events. Lets explore how wild fish respond to flooding and how these events can relate to some species we keep in aquariums.

We see destruction when we see floods occur, but for fish in natural waterways floods provide rather regenerative qualities to the native habitat. The swift water flushes sediment and debris out of pools and runs allowing fish to hide and move about more freely. Depending on severity and degree of the flooding, the layout of streams and rivers can go through dramatic changes. Rushing water can carve new and deeper pools in creek beds. Rotting wood and roots may be washed downstream, but they may be replaced with newly fallen trees and branches which create new places to hide. Sediments may fill in some shallow pools and create new gravel beds and sand bars where fish can feed and reproduce. New sediment beds are also prime real estate for scuds and other macroorganisms to colonize, creating a rich food source for other species. While the fish find refuge in underwater nooks and recesses their community gets a makeover! Trash and pollutants can also be swept away, leaving a cleaner environment once the water clears.
