I just went to my local pet store to buy fertilizer for my new aquatic plants and they had a red and white butterfly vt on display in a .8 g betta tank and he was beautiful and I bet you can guess what was in with him? A FEMALE!!! I told the head guy right away and he flipped because one of the other staff did it. The poor girl was half dead and she was so scared that if you moved in front of the tank she freaked out going nuts. The head guy removed her right away. I'm so glad I was there to tell him!!
