I was wondering if clown loaches are difficult fish to keep. I have a 100 gal tank with assorted african cichlids, and a couple of clown loaches. They seem to be doing fine, but for about a day, one went missing. He's back, and doesn't seem as active as he was before.He's just laying on a piece of slate on the bottom of the tank. Hope he's ok! The fish I have are not agressive towards them, so they are not getting picked on. Also, I have been feeding them flaked and granulated foods, lettuce, and occasionally brine shrimp.
