I bought some clown loaches who are in quarantine right now. However, they are constantly hiding in a cave I have in the tank for them and I am not really getting to observe them at all. After sitting still for several minutes, usually one or two will come out, but if I so much as tilt my head in the opposite direction they go back into hiding. Its only been a few days. If they don't start to come around, should I remove the cave to get a better look at them? I don't want to overly stress them. Or maybe just remove it for a short time each day to get a look?
