i havetwo 4" oscars in a 55gallon is there any fish i could add... upgrading to a 75 gallom later just any fish that i could add beacuse the tank is kind of boering
75 gallons would be to small for one Oscar let alone 2 Oscars, they will be ok for a good few months but they grow really quickly, I purchased two 2' Oscars last weekend, and one of them is nearly 3' and the other 2.5' they grow fast tho dude!
Anyway IF you got a bigger tank than a 75 gallon, a jack Dempsey would be a good choice, nice difference in colour to the Oscars
