Ok so I bought 3 clown loaches. I put them in my 55 with my 2 pictus, 3 cons, and 1 green terror. (yes they all live in harmony) I have had the loaches for about a month now, and 2 of the 3 will lay on their sides, and look dead for about an hour at a time. I tap on the glass lightly, and they spring up, and everything is normal. If I leave them be thay will eventually get up on their own. Tank parameters are normal, and everything is healthy. Anyone seen anything like that with their clown loaches? BTW. The loaches look great also. No sign of disease or anything like that. Bright brilliant colors. Full fins, and no sign of anything bad. They all eat great too.
