Not so good i think. They can get damaged really easily as they have very small fne scales. And they arent really aggressive towards fish that dont look like them.
im going to try to get some pics of what my armatus did to my atf. he got shanked big time. i dont know if hes gonna make it. but id say if anyone messes with him hes not at all afraid to throw down
just got a cool pic of him growing a new tooth in. i saw him bust it out yesterday. u can see the new one folding up from inside. cool to see him with his mouth open so wide to see those K-9's. i would hate to be my atf right now.
