I am new to the hobby, i have had my fish in the tank for about a week.

It is a 95 gal tank and currently i have 6 tiger barbs, a 3 inch firemouth, a 2 inch oscar and a 3 inch gt.

Ammonia, nitrite and nitrate are all at 0.

My issue is; the gt, after about 3 days, started attacking my oscar to the extent that i had to seperate the oscar into a breeding basket, his fins are shredded and alot of his scales have been taken off. The gt and firemouth were getting along fine but the day after removing the oscar the gt started to attack the firemouth constantly, he also has chunks taken out of his fin and tail. For the safety of the other fish the oscar is now back in the tank and i have put the GT in the breeding basket temporarily, plus i am medicating with melafix.

I cannot afford to buy another tank just yet as i have spent alot of money on this one.

Does anybody have any ideas as to where i should go from here?

cheers,

Harry

only 1 thing you can do really and that's return the GT to your LFS or find it another home with someone that can look after it. GT's are very aggressive fish as you have found out. things won't get any better as the GT grows so will its aggression

I completely agree with Marcus!

hi i see by your reading that your tank has not cycled, you should have nats at least around 10ppm

HI i would also try to rehome him if you carnt get him a tank to himself i had the same prob with my red devil i have had to get him a tank on his own as lfs would not even take him so i keeping him know hope you get it sorted

"GT"?
