Hi all! Quick question. I was given a giant gourami at about 4-5 inches. It was as placid and chilled out as you can get, not a problem at all to keep. Once it hit the 9-10 inch mark it started acting very aggressive and bashing other fish up, over night it demolished my 12 inch indian shovel nose and it attacked my oscars. Now someone told me this a almost a phase they grow through. I'm wondering is it a phase, or do i just have a violent fish?
 
Can't decide if i need to rehome or not. If it grows out of this behaviour then i will keep it seperately until such a time, but if it stays this way then it will need rehoming :(
 
Maybe its time to move it on then, can't risk it in with my other fish. Shame really as its a great fish, just a bugger!
 
I have 6 inch Giant Red Tail Gourami its always bothering my silver arowana that is 12 inch but when it comes the time where they feed you can clearly see that the arowana dominates the aquarium

I have the same problem, my rtgg hates silver fish. I have a couple balas it tries to chase around but really can't catch them.

The problem is the only 2 tanks i have that can hold him both contain too much value to risk putting him in. Tends to get violent when the lights go out!
 
They will always be an aggressive fish so keep them with other large fish that can handle themselves (preferably monster fish) arowanas, cichlas, polypterus, large cichlids, snakeheads, dats (depend on the size) , gars etc
 
Egon - the time WILL come, when he WILL catch them.
Mine caught an Indo-Tarpon, which is a lot bulkier and stronger / faster. (And yes, that was the end of the tarpon.)

They are one of the ultimate wet pets. I have NO disappointments having only one fish in a 300 gallon tank at all.
