120 gallon 3 fish?In a tank that small, with that many fish already, I'd be doing 80% water changes every other day.
Well there's 5 fish, the oscar and 4 blood parrots, and depending on filtration, your tank may or may not be able to handle that. Frankly, I'd just run purigen or something like that, far easier and more practical than removing 90 plus gallons of water every other day.120 gallon 3 fish?


I know but the 120 is only for the oscar and 2 big blood parrots. the other and the pleco are going to a new tank probably this week or next.Well there's 5 fish, the oscar and 4 blood parrots, and depending on filtration, your tank may or may not be able to handle that.

patience it is then.Give hime time, variety of food and clean water and he will grow even more. But an oscar only 12" is small. Ive seen 45cm oscars in person. They do get large and have potential to reach 45-50cm.
Maybe you could try pool filter sand? Sinks quickly after being disturbed, dosnt really float around or cloud the waterShould i go back to sand?
