im not shour but i would be carefull i have an african lung and he was fine with all the other fish but my burcher a day after i put him in the tank thay started fighting over taritory so he had to move i think that might be your biggest problum. but again im kinda new to them so it might be different with yours. o lol i just thought i would add he is in a tank with a 1" gold fish and there has been no attempt to eat it.
