I have just started cycling my tank yesterday with 3 zebra danios. The past few hours they were loaded with energy. I know this might be just be being worried because I haven't gotten a test kit to test for ammonia. But is being overly active for zebra danios normail, or can it be a sign of ammonia poisoning. And if it is normal, are there other behaviors of high ammonia I can look for while I get ym test kit, whcih I will get by this afternoon. Thanks for your time.
