Take away his pocket money and ground him lol just kidding dude , safety in numbers while bass are small IMO , you either need few more bass or some ditherers to spread the aggression out a little

I'm sorry to say g2 banjar Reds are very aggressive as they are a mix of a green and a red

Green aro are nearly as aggressive as jardini so a banjar is nearly as aggressive as a green

Nothing you can do sorry

POSSIBLE AROWANA SUDDEN AGGRESSION. I had three Arowos in one tank for weeks with no issues, then one was hiding only to find his tail had been chewed on. I immediately moved him to another tank only to find the 2nd aro dong the same thing, so I moved him. Then those two started going at it. I then checked the temp. It was 84. Brought it down to 79 and so far no fighting. May return them back to the original tank tomorrow. Conclusion. High temperatures cause aggression towards each other.

Arowanas by nature are territorial fish so having 2,3,4 or even 5 or 6 will cause a rumble in the jungle. One of them will attempt to be the alpha and during that time fights will happen. However, when you have more aros the aggression is no longer apart from a few nips here and there. They're more peaceful in pack. In your case I would suggest a use of a wavemaker. This will allow them to concentrate on swimming and will likely lessen aggression. No harm in trying.

I have the Fluval Advanced Filter that provides a current which they like, but that could be an addition to the skimmer as well. My point is the temperature was the cause of the sudden aggression.

Sorry Eric, I was referring to Dudefish82 original post. But I may as well comment now. I really don't think high heat was the culprit. Perhaps it played a small role into agression but like I said previously aros are territorial and you may encounter a few weeks of happiness, but eventually fights will break out and continue to break out. But, you may just be lucky and have 3 peacful aros. Are they young or old? I'm just speaking out of experience and no pun intended

Well I have two juniors I separated from the foot long one. He was nipping at their tails. However now that I have the wavemaker which is like a cellphone for Aro's I may put them back in the big tank. Thanks for the advice.
