Haven't kept any, yet. I have asked around a bit to see what would be involved. I was basically told that if you had soft water, and a quiet spot to put a spare 5-10 gallon tank with some java moss in it, you would pretty much be sucessfull. They do need good clean water, which means plenty of water changes. They also do well on live or frozen foods. If I were you, I would get guardneri (sp?) species. They are very beautiful and easily bred. These are the kind that you put them in water, they lay eggs, and you leave the eegs submerged. There's no removing them to be kept in a cool, moist, dark, quiet area in a butter tub. In other words, they are much easier to keep.
