My zebra loaches were kind of dancing. I guess that's the best way I can describe it. Does anyone else's do that? I know they don't mate in captivity... Right?
My Kuhlis did a dance a week ago. I saw 2 of them swimming in open water, grbbing each other at the mouth and swimming in perfect strokes for a few seconds. Then I saw a spray of green little pellets come out of one of them. It all landed in my Java Moss.
I don't know about the mouth thing. I don't remember, but they're in my other tank now with the other fish and lots of cover so I'll probably never know now.
