I will check Shorty. Maybe a tough question to find as most studies are done on big waters with multiple species. IIRC several of those studies cautioned about RES and PS in the same water but I think it was with BG present.

teehjaeh57 in this case the cross would need to have pharyngeal teeth/crushers to eat the snails. I don't know if that gene/trait is included in any of the RES or PS Xs.
