A Black Tiger Oscar, Datnoid, Jardini, Red Tail Cat, and Dragon Fish? All about 3-4" (with the exception of the Dragon fish (6") in a 55 gal.
How long before I have to upgrade to a bigger tank?
Will it work at all?

I already own the Oscar and cat, but the others became available to me and I havent seen any nice Dat's in my area for a long time
