I have a 125 gallon tank with 3 ten to twelve inch oscars in it. 2 veil tail and 1 red albino. I’ve been wanting 2 of them to pair up, but nothings happening so far. I would get rid of the odd one out If 2 did pair up. Don’t know if they’re males or females. I guess there’s a chance they’re all females? Tank is filtered by 2 AC110s and 2 ac 70s hang on back filters. I change 50% tank water 2 times a week. I know I’m at my stock limit already but I have a chance to buy another Veil tail Oscar. I know 4 Oscars this size is pushing it. But if I get this fourth one maybe 2 would pair up. Then I’d get rid of the other 2. Maybe all hell will break out. What do you think?
