By the time I bought my Oscar the shops here would carry mostly albino, red and common Oscars, with the occasional tiger, in only small numbers and cheap. Never seen veiltails yet, never would get any neither, lol. Every time I go to an LFS I check if they have Oscars, and I haven't seen any for sale in quite a while now. Might be different in the bigger cities though. They are not that wanted here, most ppl want either Discus/Angelfish or riftlake cichlids when it comes to cichlids. Therefore I'd never think of breeding Oscars here. There are breeders, but probably not many. Big ones are mostly only offered by ppl that need to get rid of them.
Reminds me I once watched someone asking a sales person what kind of fish the Oscars were, and she said they were angelfish

Thankfully most seem to know about the potential size of Oscars, but probably will still sell them to ppl that don't ask.
