Ok i went to a pet store today and got another 5-6" RBP, and put it in with my other 4 that i have. So now they are all in the corner rubbing each other and going in cirlcles? Are they trying to mate? at first they were would swim past the new one sideways, now the other 3 casue one other is getting rubbed too, are rubbing them selfs all over the new one in acircles, but are nit fighting or biteing. the others are poited down with their fins going very fast but not going anywhere. Could they be trying to mate? they have been doing it for almost an hour now, man i wish i had a video cam, they scatter when i get close with the digi cam, but go right back to it if i back away. PLEASE HELP!!!!! if they are mating, what do i put around the inlets to the filter and powerheads? to keep the fry from being sucked up???
