I was at Petco a few hours ago and they had these bettas they were calling giant bettas. They were HUGE! (For a betta of course). Very very thick thick body. A good 4" long. It wasn't necessarily the length that threw me of but the strange thickness of the fish. Not fat at all. No belly on these fish. Just THICK! It had a little color on it. Modest size finnage comparable to a plakat maybe just a little bit more finnage though. Are these those supposedly community friendly/peaceful betta species? I had heard that most betta species are actually very friendly and multiple males can be kept together. Just not for B. splendens.
