Hi Nicole. The first thing is that all "proven" pairs are not! "True" proven pairs are little money makers, and if very good and prolific...will hardly ever be sold off. More money in it for the breeder to keep them. UNLESS...It's someone like DiscusHans...who has proven pairs coming out of his ears! I can vouch for Hans's pairs...they're real! Fresh, clean water for Discus, and perhaps live food usually puts them in the mood. A big waterchange with cold water, can work wonders. The brief cooler temp. triggers something in them. All the best...Bill
