Ok so, since yesterday my fish have been acting strange... I have 2 clarkii clowns, and a combtooth blenny. The blenny is same as always. But my clowns are being odd. Like one of them keeps going to the front of the tank over some shells in one specific spot and kinda hovers for a few seconds then leaves. They are also really active swimming all over the tank, in and out of caves and holes. And they seem to be swimming a little weird also. I know they swim weird anywyas since their clarkiis, but they seem to be doing the wiggle alot faster now. Ive had the clarkiis for a few months now. the blenny for about a month. The only thing thats changed, is I bought 1 snail lol. Does this seem odd? Ive never seen them act this way until now.
