Oscar needs a couple buddys

  • We are currently upgrading MFK. thanks! -neo
Oscars aren't schooling fish they don't need company to feel secure. What they do need is an enviroment that is sutable for their long term survival. Such as good water qualty, cover to retreat to if they feel threatend and a space big enough to provide the first two, along with open swimming space so they be out in the open when they want to. That's it. To the OP I would up grade to a biger tank ASAP a 75 to 90 would be perfect for your O to live a happy life as a solo fish.
 
Agreed. To have enough room for adequate waste dilution between water changes and physical space for the fish to pace, my 75g was actually too small for my O! I was underfeeding for a few weeks as I scrambled to get the 125g up, and even with best efforts, nitrates were hovering between 15-20ppm. Not my idea of good fishkeeping. So I would strongly advise 90 US gallons for the typical fishkeeper like me, who doesn't like doing daily waterchanges.

If you start with a concrete amount of maintenance you're willing to do, add the fish you'll keep and adjust for metabolism, food type, and a few other factors, the tank size required will spell itself out for your individual needs. With experience.
