Hello! I have a tank of American cichlids and Rainbows and three Congo Tetras, and just bought 2 medium sized clown loaches (about 3 inches long) three days ago. As soon as I put them into the tank, they immediately disappeared! Later that evening I saw one just peeking out from some lava rocks, but I haven't seen them since! The larges fish I have is a Vieja Synspilum who is approximately 5 inches long, but nowhere near big enough to swallow the loaches. I moved all the lava rocks aside this morning--- they weren't there. I do have a big, hollow tree branch type decoration that they may be hiding in, and I shook it gently, but nothing swam out. I'm worried because they haven't even come out to eat if they are in there. Could they be hiding under the gravel I haven't seen any fish remains floating around either. Any ideas?
Thanks!
Thanks!
