Ive just purchased a large oscar 20 cm. i have 2 tanks a 190 litre and 400 litre but i have put it in my 190 litre due to the fact that it could easily eat my showl of small torpedo barb. he is with 3 medium angel fish and 3 clown loach . up til now there are no problems and he seems peaceful and quite but will this last as i read different opinions about oscars... i just wanted to risk it as he looks sooooo nice . thanks
