Hey guys!!
So my friend's gonna give me a 20cm tiger oscar.
I have a 25-gallon aquarium with two 4~5cm clown loaches and two 6~8cm clown loaches.
I also have a baby pleco, some pieces of rock and one piece of driftwood.
I just want to know if I could keep my friend's oscar in my tank.
I'm only going to keep the tank for 1 year, so...
Some info would be appreciated.
