hi, been on the brackish water section about keeping dwarf puffers & was told i should try here. So, I have a cycled 6g planted tank, with 4 neons & an apple snail & would really like a puffer fish, would it mix with the neons? should i remove them & add marine salt to the tank to suit a puffer? Can i keep a puffer in saline-free FW? if so, which species?
many thanks
