A question aboout clown loaches

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.

 

hi nano clown loaches are schooling fish so they do like to with at least 6 of there own kind but they are known to play dead they like to lay on their sides hope this helps

 

Clown loaches were my favorite to keep, they help out a lot when it comes to snail infestations. They do best in groups of 4-6 and up due to how they are schooling fish. If you see them on the bottom "dead" dont be worried, they tend to play dead and jump right up. Feeding is pretty easy, they love snails that come along with live plants and flake foods. Also as a nice treat they have little tabs that are like algae tabs that they love.
