Looking for some help

[Alofrisco]

I have a 55 gallon tank that I am going to set up for green spotted puffers, I've seen on youtube the puffers and bgk living together and would like to know with the right set up if I can do this. I already have the bgk, About 5 inches. But I wanna know about water conditions ect.

Spotted puffers are freshwater when young but require brackish in adulthood.

Welcome to AA! Black ghost knife requires a different setup to a green spotted puffer. A G.S.P needs brackish , and then I think fully marine. And need about a 20-30 gallon tank. A black ghost knife requires freshwater and a tank of 120-150 gallon.
