I don't think yellows can be easily enhanced. I may be wrongI think lemon Oscars are either died or are feed the supplement to pop out Yello through their skin and it's a luck by chance thing.
Thanks for explaining. Your pair were absolutely stunning! I'm amazed at how there wasn't any interest. I'm sure this will help point people in the right direction now anyhow. It's a shame I'm from the UK or I'd have to inquire about someI tried selling 2 spawns several years ago. I had no individual takers. Wound up selling both batches to a transhipper that sent them overseas. Sold the breeding pair and the 3rd batch of fry to a guy in Memphis. Never saw any sign of the Sunshines since then. I bought my young sunshines from aquascapeonline. Pedro best-guessed a m/f pair for me and he was spot on.
Cool little oscar but Looks like regular Lutino to me? Shouldn't lemons have no black in their fins?
Or is lemon a name used for yellow Oscars?
