I have a 29 gallon tank which has all tetras (rummynose 6, pristella 6, glowlight 5, amano shrimp 2, platy 1). I've been debating on whether I add one or two pearl gouramis. When I punch it in aqadvisor.com it says that the gouramis could become to aggressive for my tetras if they breed.
My question is do you think I'd be fine with 2 pearl gourami's (1 male 1 female). Or should I just go with 1 pearl? Each gourami will be about 4-5 inches. Close to full grown!!!
