Hi,
My Colomesus Puffer is very fussy and will not even eat bloodworms. It's got to be live and wiggling. He does love live ghost shrimp though (but I tried frozen ghost shrimp - he wasn't even interested)
I have a Colomesus Puffer and am going away on holiday for two weeks.
He's in a tank with 4 small plecs and 4 platties and the other fish have always been fine with holiday food blocks.
However, my puffer will only accept live food, and at the moment, only live shrimps. I will make sure...
