Any help would be awesome, already have 2 green severums and 1 blood parrot want to add red bay snook. Severums and parrot are pretty calm I don't forsee any problems. Also what are you feeding your snook, I don't like to use live food...I just bought mine today and he is only the size of a quarter got him in a 10gal by himself till he is big enough to go in my main tank.
