Stick Catfish Spawning

By Jim Benfer

In the April 2013 issue, Jim Benfer profiles stick catfish. For those who are interested, stick catfish can make for a challenging breeding project. These videos and brief descriptions below may help you on the path to spawning your own stick catfish.

Breeding males entice females to spawn with them on vertical aquaria glass near the water surface beginning in the overnight hours.

Usually, the females deposit two adhesive eggs side by side, starting closest to the surface, and working downward until a double chain of eggs has been deposited and fertilized.

Goldfish Wheelchair

We all know that there are people who go to extremes for their pet fish. Some dedicate entire rooms (or backyards, or basements) to them, some raise live foods, others conduct daily water changes, and at least one goldfish keeper built his disabled goldfish a flotation device so it doesn’t have to rest on the bottom.

Check out the video below to see the fish wheelchair in action!

Keeping Arowanas

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.

Giant Kribs Breeding

 

Giant kribs (Pelvicachromis sacrimontis).

By Ted Judy

Excerpted from the November 2012 “Cichlid World” column.

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.

Water Testing Demonstration

In the July 2012 issue, Wesley Devers discussed the importance of water testing—a fundamental and vital aspect of ensuring the health of a tank and its inhabitants. We were fortunate enough to run into a professional aquarium caretaker at our local fish shop and captured a basic look at the process. Check out the video to get an idea of the tools employed and which parameters to monitor.
