I've seen them on dogfaces and I've seen them on green spotteds. Right now the LFS has a 20 gallon tank full of (over 12) GSP's that all have several of them. They did not have them when they first came in. I've been told that they are just bite marks but the source was not very trustworthy and i kinda don't buy it. They are all perfectly circular in a way i would not expect from even a puffer mouth. Also, the time i was told that it was bite marks, it was on a dogface and the only other fish in the tank was a clown trigger. Again, the spot was a perfect circle and identical to the ones i now see on the GSP's. Again it seems unlikely to me that a trigger would leave such a mark.

I do not have a photo of the actual GS puffers (though i might take one soon), but i found a photo on the net which looks identical.

hope my img worked. haven't used forums for a while. it's on the belly.

anyways, it looks exactly like that. I've seen it many times, often times on fish which are not being properly cared for or sickly in other ways (then again most LFS's don't seem to keep brackish puffers very well). the LFS is keeping them at 1.005 salinity if that is useful information at all. they are on a gravel substrate with almost no hideouts, and yes they have been biting each-others fins up. they are mostly fed bloodworms and pellet.

any insight would be greatly appreciated. thaaaaaanks.

That's a bite from another puffer.

oh wow. i guess the guy was right then. except when he said it, there was just a trigger in the tank. but i guess it's the same thing. usually the guy is full of you know what, but i guess even a broken clock is right twice a day.

thanks
