I put 6 Zebra Danios into my tank 2 days ago. I gave up on the fishless cycle. When I put the fish in they seemed fine. They always swam at the top though, but then a few hours later, all the fish started swarming toward the bottom and then a in little while swim back up. I didn't even add food so they couldn't be scavenging for some. Is this normal? They did this again today. I always thought they swam at the top more often.
