I no theres a lot of fish in there but i have grown them all out together they were in a 55 untill a month ago when i bought a new tank it is 150 gallons but some fish might be moving out like the fh cuz its getting too agressive besides that they all get along together except for the red devil which i recently bought. Im still not sure what it is though I hope someone witha lot of red devil knowledge helps me outNCStateFisher;4735844;4735844 said:dang how big is this tank? oscar FH GT and RD? that's a pretty hefty stock
