My Oscars Fish Tank

  • We are currently upgrading MFK. thanks! -neo
Your oscars look great, just wondering if you planning a bigger tank any time soon? 330 litres (90 gal) is abut small for 2 adults oscars, I'm sure they would love some extra space.

Nice colors on them, but your going to need a much bigger tank very soon, A 6' 125 gallon at the minimum is going to be needed to house 2 adult Oscars. It's impossible to tell the sex of Oscars by looking at them, they don't have any marks or colors that separate the males and females.
 
Oscar usually reach sexual maturity around 1 1/2 years old, which will give you 2 12" fish in your 48" tank with whatever that other fish in there with them is. Not a recipe for success, your water change schedule will be off the charts trying to keep nitrate's below 20 in that set up.
