One of the fish in the tank has been constantly following another... like all over the tank -all morning - and the one who's being followed keeps trying to get away and the other just follows. It won;t leave it alone.

It seems like it wants to be alongside the other constantly. I don't see any biting or anything like that.

Any ideas what's happening here? They are both Tetras but different kinds.

That's why it's important to have fish in the right numbers for each species. It cuts down on aggression and pestering. And it's also why there should be a lot of hiding spots/plants in a tank so the fish being pestered can hide out.

I know you're working on that.

We put five artificial and silk mix plants in the tank a few days ago.

I have noticed this particular fish is aggressive towards all the others, however, he is really bad today on one
