I have a 8" giant gourami in my tank and have just put a 9" scleropages jardini to go in with it but the strange thing is, the jardini is following the giant gourami around and then the giant gourami is kissing him on the scales, its not a very aggressive bite but im worried, if i have to the giant gourami can go but my mum is obsessed with gary the giant gourami and its going to be hard to split them, any suggestions?
