Puffer with big teeth

[bluepenguin]

I have a dogface puffer that has developed an overbite and I don't believe he can open his mouth properly to eat,his teeth are huge. I know they are supposed to wear them down by chewing on coral and such but he isn't. Other than that he is healthy.
It may sound funny and I am not a novice(I used to import and export marine fish) I have just never seen this before :confused:

The condition is treatable with filing. Most people encourage their puffers to go after shell fish--mussels and common clams can be fed in the shell, forcing the fish to chew. If there's not a feeding imperative, many puffers won't just chew on rocks.

How do I go about filing?
I have encouraged him with live clams but he does nothing he sits on top of it

I've never done it. See if you can pm appaloosatb. She might be able to offer some tips. Or, if you can find a vet that specializes in treating exotics--maybe a local aquarium or zoo? I have no idea how it's done with stressing the heck out of the fish--knocking them out, maybe? I just know it can be done.

Another thing to try, if you can find them, would be some small clawless crawdads. The movements might be more enticing than a mussle or clam. They have a fairly high tolerance to SW, so will stay alive for 4-5 minutes easily, longer if you acclimate them a a bit. Worked wonders for an octopus we had a while back.

Did you do anything to the clam before presenting it? I feed my clown trigger live clams, but if I don't crack it for him first he can't open it. He then loses interest after a few minutes. Once he smells the meat, he tears the thing up. I've never seen a puffer/trigger reject a live clam, but if you haven't before, crack it open to allow him an access point.
