Glass Catfish - Kryptopterus minor
Glass cats are timid schooling fish, and must be kept in groups of at least six fish in order for them to feel secure. They rarely do well when kept in small groups or singly, as such a situation is very stressful. These fish benefit from having a heavily planted environment because the plants provide shelter.
Glass cats are not strong swimmers, and so should not be kept in tanks with high currents. Glass cats are also very sensitive to water quality, and will succumb to disease quickly if the water is not kept clean. It is important to do small frequent water changes in order to keep these fish healthy.

I could probably have a tank filled with just Glass Cats and rummy nosed Tetras. Get yourself some red colored flake food because its cool to watch them swim around with it in there mouths. There a very happy, fun fish to watch and what I like most about them is they don't hide all the time, they like to be out front and center so you can watch them. All around a great fish for your community tank.
Tank Conditions are Important
I've had seven of these for two years. The biggest challenge is getting them to eat in a community tank. They are not aggressive and the other fish will eat all the food. You have to develop a feeding strategy based on your tank size and setup. I have them in a 55 with a power head at the top right of the tank shooting across towards the filter return on the left side of the tank. This creates a circular swirl water pattern that makes the food drift by on the front of the tank where they school. They snatch brine shrimp as they drift by. This is nice friendly fish that is entertaining to watch school and eat. The 7 of them hang out in the front middle of my tank just schooling against the swirling current all day long. If they get tired, they shift a little towards center to be against some stacked slate caves to modulate the strength of current. The guides that say don't have them in a tank with a current are wrong. They like a constant weak current to feed and socialize.
Very cute and interesting
I have 2 in a 10 gallon and they are so cute. They come out to eat and it is so funny!
These guys are adorable! They are very interesting fish to add a community aquarium, a couple things you should know is they are most active when the aquarium light goes off and kind of hide away in the day. Also keep them in a school of 5 or larger they get very stressed when they don't have others around them.
