I've never kept a beta in all my 45 yrs of fish keeping, but I was asked a question. A relative of mine has a 50 gal long tank (4 ft) with 6 green corys, 2 bolivian Rams, and 6 denison barbs. He and his wife asked about putting 2 to 4 female beta in their tank. Or just one male. They're finding a lot of mixed views online, as I have also while looking for info. I told them I'd be more worried about having a male in with the Rams I'd suspect issues possibly there. Any expert advice I can give them, please?
