Questionwhat tipe of fish can i put in the tank with these fish? the tank has a brown colour and i beleive it could be alge.
AnswerFirst of all, you need a big enought tank for just an oscar. An oscar needs 55 gallons for only on, 75 for two, 100 for three, 120 for four. You also need a massive canister filter. These are the most messiest fish sold today, and not alot of people can take care of them.
First of all, what size is your tank, and what is your filtration?
