Some fish was having a good time chewing on the male guppies fins. I noticed that they were a little tattered, but nothing serious. The next day the one that had the biggest caudal only had his pectorals left and the other had half of his tail gone. I suspected the rainbow cichlids as we didn't have a problem before them. I put them in the Q tank with some pima and mela and they are starting to grow back. I noticed that they spar with each other in the q tank. Do they do this much damage to one another? There is 2 females in the community tank wherre they are normally.

Think you might have answered yourself
