What Other Fish...

[dcj38]

In my 90 gallon right now I have an oscar and 5 silver dollars but I would like to have one more fish in there so can someone point out some options that are open to me... I was thinking of a bottom dweller, but use your imagination

I would think a pleco might work, but I am very wary about overpopulating the tank. Oscars, and even silver dollars on occasion, can be very messy. I'd like somebody else to reply to this also, I'm in the process of cycling a 90 gal. that will have silver dollars in it.

I think youre already over stocked for a 90 gallon, a Oscar should have at least 75 gallons to itself, so that leaves only 15 gallons for the silver dollars.

oscars should have at least 50 gallons to themselves, its just recommended that 75 gallons is better

Even if it is 50 gallons, you are still overstocked. Oscars and silver dollars are quite messy hearty eaters, requiring good filtration and frequent water changes. Even if you had room for the extra bioload, the aggression from the oscar wouldnt allow it. To be honest, you are pushing it right now with the 5 SD's and the oscar.
