How can i get my betta to grow long beautiful fins like the pictures that i have seen on the internet of other peoples bettas? i thought mine had pretty long fins, but then i saw how long they can reallt grow. Does anyone have any suggestions for me? I have my betta in a 5.5 gallon with a couple platies and a dwarf frog. I have been watching the platies and they do not nip at him at all. Is there some kind of food or something that i can give him??
