Danios Flashing or Playing?
I read the other day that danios will sometimes look like they are flashing by bumping plants (not decorations) in a tank, but it said it's not hard bumping and they should not do the crazed swimming that a flashing fish does, rather just gently bumps into a plant and then goes about their business of chasing.
I do not think I have any trouble with my tank, but of course after I read that I had to watch my danios, and sure enough I saw one or two actually do this in a 5 minute period! There was no crazed shimmy like a flashing fish would exhibit. As soon as they saw me they swam away and wouldn't continue, but now I am concerned.
Has anyone ever seen this behavior in a healthy fish, especially danios?
