I have been reading that cory catfish prefere sand on the bottom of their home. I like undergravel filters (I also use an outside hanging filter. Better super clean than unhealthy home.) I have smooth, reasonably fine gravel and the corys seem to be OK. But, I have not provided catfish with a home before. They are in a 10 gal community aquarium that currently has 2 neons (I want a total of 6), 5 male guppies, and an albino cory and green cory. If I need to switch to sand, I will loose the under gravel filtration. But I want happy catfish. The aquarium is decoratend with some live potted plants, plastic/silk plants, and resin hidding logs. I have taken an interest in oto catfish lately and have thought of adding 2 to this tank. That might make a difference in the bottom strat too. (Yes, I know I may need to move the guppies if I add the otos.) Catfish do add a charm to the community. Thanks for the help.
