Hey guys - A few weeks ago I started stocking my freshly cycled 30 gallon tank with 5 cherry barbs. Last night, I went to the LFS and added 5 more. After acclimating the new ones, they all seemed to be getting along fine, exploring the tank and schooling together. I get home from work today and my wife says that they have been chasing each other all day. A few of the males (I believe - they're a very vibrant red all over their bodies) have been chasing each other, as well as the not-so red cherry barbs (I think these are the females?) around the tank. I got home, fed them, they all ate fine... Nobody has gone into hiding or anything, so I'm not sure if it's actual aggression or if they're just playing. Thoughts? If need be, I'll post a video in a bit to show what I'm talking about. Thanks guys!
