[ZackB]

hey iv bought male blue Japanese fighter fish and a big sucker fish and also another fish but that one doesn't bother either of them but the other two when ever the Japanese fish comes near the other one they both go crazy and swim like mental things but they only do it for a few seconds are they ok or not ???

Fighter fish is an aggressive fish, but don't worry, after couple of weeks, they will get well along each other, I mean they will not bother each other. Its normal at new introduction.

Sounds like your tank isn't big enough for the big sucker fish and they can't escape each other. If they had enough room they would simply keep out of each others way.
