Ok, I know that bettas can't live with fish that have flowing fins, but I can't find anything about cowfish. I just love these guys! Can one move in with my betta if I get a big enough tank? And, how big is big enough?
Um..... First off, a short trip to Google and some prior knowledge tells me that Longhorn Cowfish are saltwater fish. Bettas are freshwater fish. They are in no way compatible just because of that. A short trip to Google also told me that Cowfish need an 100 gallon tank minimum. In short, you answer is no way.
