hi, i have a quick question on puffer fish. i will be setting up a community tank with a ghost knife and a pleco. idk what else i want yet but i have the pleco now but want to buy a ghost knife. the tank size is 35 gal. i dont want a brackish puffer. i want a true FW. i looked at the other threads and didnt find exact information. i dont want a puffer that will kill all my fish. i want a kind and polite puffer. lol. if it grows out of my tank i could put it in my 75 gal with a ray. so which type of puffer would be best suitable for the information i have provided? i wouldn't mind kepping 2 of the same kind puffers. or even 2 different kind. so just let me know.
