Just got this betta 2 weeks ago from Petsmart. He was in pretty bad shape, but a 20 gallon tank with clean water has his fins looking much better. He was mislabeled as a Rose Petal, and he isn't. Can anyone tell from pic what tail type he is. His color flashes from black to silver depending on his mood (?). Thank you for such a great forum, I have already learned so much!
