i have 9 pygmy cories in a 10g planted tank. They are ALWAYS hiding in one back corner by a large sword plant and rarely move at all during the day/night. Is this normal? I was under the impression they would go around all over the tank, but they seem to hide out, unless scared by my hand going in (to move plants/prune) and then they will quickly dart around the tank and settle in some other corner where I can't see them well. I was just wondering if this was normal and if there's any way for me to get them to come out. They do not seem to seek food when I toss down either an algae wafer or the wafers made for catfish (hikari brand for both), and I never see them eat.
