The Puffer Forum

I just got a GSP...well I mean about 3 Weeks ago but it is the newest puffer and I am housing it with my F8s and I just want to ask at what age or size roughly should I shift it to full marine ( a tank on its own)? It is currently living in a low brackish environment temporarily but I know that as it gets older it should live in a higher salinity environment. The GSP I would say is pretty young (not even 4 cm yet).

GSP are generally more boisterous than F8s. I would move him to his own tank asap

They are very cool fish, but yeah quite aggressive compared to F8s... my 2nd puff (f8) that I got a few weeks back had quite a few bite marks and fin nips that are currently healing. LFS told me they were all like that (about 6 of them) and it was all from the single GSP in the tank.
