Hi so just to get started I have 2 GSP in a 45 gallon that I'm converting to brackish as we speak and I plan to upgrade as my fish grow out the space in my tank. My LFS has 3 tanks of brackish fish in the back and they just recently got the coolest little Datnoid that's already converted to brackish I would love to take home for my tank but first I must know would he do ok with my puffers as they are all brackish and the Datnoid is already a little larger then the puffers?? The store I go to in Austin,TX Aquatek also caries "archer fish, multiple gobies, chromis cichlids, sailfin mollys as well as a few different types of Scats and monos oh and of corse other puffers" all of these fish are small around 2-3 inches and my puffers are only maybe 1-1.5 inches what out of these fish can I house with my two puffers and hopefully that silver Datnoid??? I'll follow the advice given as I would really like to see my tank thrive but I was really hoping maybe I could as a pair of green Scats and maybe a couple monos? Idk but hope to find out if I can do all of this soon I have about 60 in store credit that's burning a hole in my pocket!
