So to eleviate some concerns for the Oscar: At 5-6 inches, when the Oscar would be the dominant fish I'd put him in the 125. Keep the 29 to rehome other fish you have to reduce the bioload as needed. You'll fall in love with your Oscar when it matures and it will be easy to decide who stays with him and who goes, it will all be about him/her once you fall in love with his ridiculous antics. Start with the Africans or get rid of them before hand. I'd love to try raising a lemon Oscar but am maxed out on tanks at the moment. With the exeption of the ones they call ruby reds the lemons are my fav color morph (if that's what you call it).
I agree with this. Personally I would just move the Africans to another tank, or sell them, especially if you are wanting the "wet pet" experience from your O.
