I currently have 6 adult Oscars in a 100 gallon tank. They have been there for about 5 months now. I have been performing a 30% water change everyday with about 60% on weekends. They were size 7 - 7.5 when I got them.. Now they are about 9-10 inches each. I intend to keep them in the tank for another 4 months.
Readings in the tank.
Ammonia - ZERO.
Nitrates - 10-20.
I posted this on another forum and was advised to come down to 1 oscar in the tank. So I have upped the water changes to almost 50% daily till I get my next 100 gall after 4 months.
All the fish are healthy, not aggressive, eating well and swimming around minding their own business.
One pair is in the process of mating I think.
Any thoughts?
