If the tank is big enough, males of different species can live together without issues (as long as you don't introduce females). But all specimens are different, so closely watch whether there is aggression between them. If it's too much, put one of them into a different tank. I never kept Beta, so I can't answer that question.Oh blimey! That's not good news! But thanks. Is he likely to fight with my male double red? Do I need to get him out? Could he live in a smaller community tank with a male beta?
Thanks so much, unfortunately we already have a female in as they were sold as a two female and one male group!If the tank is big enough, males of different species can live together without issues (as long as you don't introduce females).
