Ya that's my worry. They beat each other up a lot. Never seen them go after larger cichlids but hate to risk it. I've had the darn things a long time. They've seen a lot of action!!!
Well a little baby giant gourami could be quite delicate.... My blue gourami was really tough though... He died a few days ago and was 7 years... I would try it but observe them for a while... Have a backup tank or divider ready just in case...
