Your two Green Severum look to be male and female, if this is the case, they could be trying to breed and that would explain the aggression towards the other Severum in the tank...

Also, get rid of the CAE... they are nasty as adults.

SOme sevs, once adult, will simply not tolerate other severums in their space. Even if your two larger sevs are a M&F, there is no guarantee whatsoever that they will pair off. Sevs have a mind of their own as to which of the opposite sex they find attractive, or not.
My advice is to decide whether you are happy with only one sev or not. If you are, then keep the large bully and rehome the others. If you want multiple sevs then you need to rehome the bully, and maybe even others too and continue trying to find sevs that will tolerate each other. It's unpredictable. As you probably know, sevs become territorial very quickly about the tank they are living in and become less likely to accept others.
I can strongly recommend something like a pair of uaru to go with your sev. Large angels also go very well with sevs.

Good luck
 
Easy answer: More aquariums to move aggressive fish into.
Best answer: See above, repeat.
 
In the few months that I have kept severums, I have noticed huge behavior swings in them. A sev which used to be dominant at one time has turned out to be submissive. I've had a sev that had not eaten for more than 2 months, but now its started eating on its own accord. So i guess these are really unpredictable. So I've decided to wait and watch. Right now there is some aggression but nothing serious. No injuries and stuff.

So I'll wait for some days and if things really go out of hand, then I'll keep the biggest male and sell all the others.
Meantime, I'm also looking for other tankmates for my fish. I'm particularly interested in Uarus. But very hard to find in India.

Anyone knows if Uaru's can be imported to India?? Any suggestions?
