Glass catfish are very sensitive to a high change in pH, and are hard to feed unless they are kept is shoals of at least six. It is impossible to tell a male from a female, but it is quite easy to tell K. minor from K. bicirrhis as I have found that K. minor has a darker head. There are no detailed reports of breeding, making it extremely hard to breed them. These guys like to be fed live daphnia and other live food and once eaten, the colour of the food can be seen in the stomach. As I mentioned, they might not eat, become very stressed and die if not kept in a group of at least six. You can tell if they are stressed because they start to turn white and when they die they turn solid white.

I have had a Glass Catfish for a little over 8 years now, and unlike stated in the last comment, it eats just fine alone. When I bought him he was the only Glass Catfish I owned, and to this day he is still thriving as my only glass catfish!

Glass Catfish are nice, hardy community fish that can be kept with a wide variety of other species. I have a school of 6 in my 240 litre and they appreciate the plant cover. Having these fish in shoals is crucial to successfully keep them in your tank. If not, they probably will pine away and die. My fish eat frozen, freeze dried and flake food, and are not fussy with which brand it is.

I have kept glass cat fish for over a year now and consider them some of the best fish you can own. They can be feed a variety of foods and will happily take flake food, however the are a micro predator and so enjoy live food. They seem to like Daphnia in particular, and they will change their normal habit of just ‘hanging’ in the water and start to demonstrate speeds that could compete with Danios. If you keep these fish, watch out for their whiskers being held backwards rather than the normal forward position, as this is an early indicator of them being sick (this will often occur before the whiting of the body mentioned in other comments). In general they are a peaceful fish that can be kept in most community tanks, but should have a decent flow rate as they like to swim into the current and ‘hang’ in the water when not feeding.

I have two Glass Catfish that have thrived for over 6 years now and they are very hardy and good for beginers. I have had no problems feeding them flake food and freeze-dried bloodworms. They like to just swim agaisnt the filter and gobble anything up. I got one of them in 1999 and the other in 2000 and they stay together along with my black skirt tetra and pleco. I have noticed that my fish sometimes have their heads put together and they swim that way across the tank. Maybe they are a male and female but I will have to wait and see. I am now in the process of moving them from their 40 L tank to a larger 110 L tank. They don't seem to mind having a pH of about 7.4-7.8 and a temp of 27°C. I love them and plan to purchase more.

I have had my catfish Earl for 1 1/2 years in my 200 liter tank. He used to have a buddy Ed, but Ed jumped the tank one day, and that was about one year ago now. Earl has been doing just fine living with an assortment of tetras, cories, other catfish, 3 plecos, a rope fish, killies, loaches, 2 silver dollars, and snails. He eats flakes, dried and frozen bloodworms, and once in a while I throw in some cucumber slices. The fish and snails love them! I love my fish Earl. He and almost all my other fish travelled in a cooler in my car for 18 hours when I moved to another town.
