sushi here. I know tiger barbs aren't supposed to go with these fish but in groups they're not so nippy. I've got 5 and could easily get more. I's wondering if it'd be ok. I have got one gold gourami. It's lovely, never aggressive, i think it's a female. Would a betta be ok. What do they do if I do put them with other fish? Do they attack them? IF I got a male gourami also, would that not be a good idea.
