In the February 2012 issue, Tobias Lim Koon Li describes the beautiful and majestic South American silver arowana. That is just one of the many different types of arowanas he keeps in his 13,000-gallon pond. Check out the video below for the basic information and care requirements of the other types of arowanas that he keeps.

Mark Denaro recently had the opportunity to visit the Long Island Aquarium, and he wrote about it in the February 2013 issue. Taking an armchair tour of an aquarium is great, but if you can’t go, seeing a video is the next best thing. Take a look below for videos of two highlights at the aquarium: a 20,000-gallon reef tank and an 80,000 gallon snorkel tank.
Are you looking for a way to light your Christmas tree without increasing your electric bill? Well if you happen to have an electric eel on hand, you can follow the lead of the Living Planet Aquarium in Utah and rig up the lights to the eel’s tank. Every December the eel is the source of electricity for a dazzling Christmas light show.
“We took the voltage produced by the eel via stainless steel electrodes and used it to power a sequencer,” said Terry Smith, Project Manager at Cache Valley Electric. “The sequencer takes the voltage the eel produces and operates circuitry that flashes the lights, fast or slow, based on the level of voltage he puts out, ” said Smith. Each time the eel moves, the lights on the 5ft tall tree flash intermittently using 4 strands of holiday lights.”
You can check out the eel’s holiday display in action below.
Almost everything about the wild origins of the giant krib (Pelvicachromis sacrimontis) is unclear. We know that the fish come from the Niger River, but we do not know exactly where. I find this a bit odd because someone has been collecting them by the thousands for decades. Whoever mans the nets must know where they are, but the fact that outside of Nigeria we are still in the dark on the issue is a testament to how difficult it is to get into Nigeria to learn anything first hand.
We know that wild giant kribs are not nearly as easy to get as they used to be, and that is all the scarier because we do not know why. The C.A.R.E.S Preservation Program has listed P. sacrimontis on its Conservation Priority Species at Risk List because we have to assume that exports are diminishing due to the fact that wild populations are also diminishing. Very little of the Nigerian rainforest remains intact, and the area of the Niger River Delta around Lagos (where we assume the populations of giant kribs are located) is heavily impacted by oil drilling and the burgeoning human population of the capital city.
Twenty years ago, the fish were available year-round, but today, the exports are very seasonal. Wild fish come out of Nigeria for only a few months each year, and the numbers of boxes are limited. Most of the receivers of these wild fish are specialty importers rather than the general wholesalers who used to get them so frequently. And the price is higher. Sadly, giant kribs are rarely found in aquarium stores anymore. That is not an entirely bad thing, however, because increasing prices drive down the demand. The hobbyists who are willing to pay the price will be the responsible keepers who really want to work with the species.
For those willing to make the effort to acquire and work with giant kribs, as the video below shows, they make excellent parents and breed readily.
Tobias Lim Koon Li has a pond, featured in the August 2012 issue of TFH , that most fishkeepers can only dream about. It features monster fish, such as full-grown red-tail cats, tiger shovelnoses, arapaima, alligator gar, and much more. One of the many challenges keeping those kinds of fish is having a filtration system that can handle the massive amount waste produced.
Tobias developed his own impressive filtration system, that can be seen in his video below.
