Euge, it's not a Fahaka. I would be insane to put these dats in with one of them. Its a T. Mbu. I have had it for a few years now and it has grown some, I didn't get it from RG, I wouldn't attempt to ship a big puffer that far. So far it's getting on with the dats but puffers usually investigate with their teeth first so I'll let you know if she eats one!
