hey guys, had a question for ya about my two clown loaches. I always see them swimming together, they are fairly juvenile, at about 2 1/4 inches have been tank months for many months now. lately i've seen them floating together amongst my sword plants resting on the leaves. tonight i came home from work, now my female is sitting at the top right of my tank floating vertically, and my male is on my left side, basically sucking my heater, floating vertically. Is this a normal thing? I've just never seen them swim apart before, I've looked closely at both, neither of which appear to have any signs of ick or anything else, and all my water levels are normal.
