So your planning to stick yellows in with your kissing gourami, RTS, bristlenoses and cories?
It could work I don't know how the cories would fare most likely ok as the yellows wont bother them they're so different..
Its a rather unorthodox mix thats for sure, I have seen similar ones work and had people buy fish of me to stick them with similar.. However everyone who has come out and seen what a full african setup looks like has come back and got more africans and gone that way separated all their others out into smaller tanks or sold them I think the fish do alot better when kept with compatible tank mates.
Also regarding the trademe auction the mods here are very tough on any contact or anything regarding trademe auctions on here so everything has to go through trademe.
