I have rocks in the bottom of my beta tank. Most of them are smooth and colorful, but there is a minuscule amount
that are odly shaped. (they are like jewels, I bought them because they were pretty.) HOWEVER my beta likes to almost dive straight down into them head first, and I can't seem to figure out why. Every so often he attacks them and makes them fly a little bit, but its not often that he does either of these, just something I've noticed. Is this something I should be concerned about? I don't want him to hurt himself.
