Yes, there is a rule you are unaware of. It's posted in the brackish forum and OG moves puffer threads there.Bosemani Fan said:I disagree Roan, Dwarf puffers are FW not Brackish, so why post a FW fish question in the Brackish forum? Is there a rule I am unaware of? Anyway, Dwarf puffers will reach 1" , they need 3 gal. of water per fish! They don't care much for flake food, but will eat it, They like Bloodworms the best! They are notorious Fin nippers, although I keep 1 in my 55gal. and it doesn't bother any other fish! stocking Ratio is 1M / 2F. Here is a site that deals with Dwarf puffers: http://www.dwarfpuffers.com/
