I never said I saw gambusia robbing nests in 2-5 feet of water, my point was to leave a good fathead foundation in it's place. I agree with the initial post that gambusia will outcompete fatheads for survival and that gambusia will eat fathead fry. The reason gambusia were used here initially was to eliminate mosquito larve, a.k.a their alias mosquitofish, they will prey on small fry, and most small fry do originate in nests. Either way, they are only a starter food used for an initial kick-start, they will not provide a true forage foundation. Stock gambusia if you're looking to put a dent into fry reproduction.
