I just recently got a a new 50 gallon tank and got with it 7 convict fish and 2 clown loaches. Ive put plenty of hiding places and my clown loaches must be hiding in one of them somewhere, i havent seen them for about a 2 days. And im a bit worried as if if they are eating their food, i have been trying to feed them bloodworms and flakes and i also have sinking food tablets and floating pellets. is it because there are so many convicts and is there anything i can do to make them come out or is it just natural?
