I went to Walmart today and saw a fish whose body was covered (about 90% of it) in fungus and he was still alive. There were many dead carcasses with their eyes/stomachs eaten out, and the only bettas left were females. Thankfully, they were all still alive. They had three light colored females with this shipment which is unusual for our Walmart... Two are cellophane and one looked like she may be yellow. I wanted to take her home SO badly, but I'm sticking to ordering from breeders because I have seen so many scary things there and I'm afraid it would introduce something nasty into my tanks.
