Angelfish Aggression

[Gooner]

Why after six months would my two largest Angelfish start scrapping? I am pretty sure it is aggression and not some kind of mating ritual as they do side swipe each other and the top fin stands erect with vigorous head shaking. There is also some mouth locking with damage to one of their lips.

Nothing has changed within the last six months (except water ). There has been no aggression from any fish in the tank except when two Opaline Gourami`s were introduced and susequently removed about six weeks ago.

Has anyone had the same issues, if so, what was the outcome?

we got our two angles at the size of a 20p and they were fine until they got bigger and now one is more dominant than the other. Nothing major to worrie about the most damage has been a few split fins. Your tank is big enough so once they've decided a pecking order it will probibly die down as the bullied ones will avoid the bullies

I adopted someone else's angels as they were in a small tank alone and constantly fighting. I got 2 more angels a month later who were also fighting. All 4 get on well with no serious bullying or injury -fingers crossed!They've calmed down a lot now in a larger 3ft planted communnity tank with livebearers and the larger rarely bullies the others.
