Hi all, on here for my friend this time. Her betta got a red blotch on its' stomach as of two or three days ago. The blotch had a small red string on it earlier that just went away after we took pictures. She has a large female that she feeds a lot and is bloated (trying to help stop that btw). She's in a smaller tank thats about a gallon and a half, no filter or heater but room is warm.
Fish is really active and friendly and behavior has not changed. We just want to make sure its nothing serious. When the pictures send I will try to post them here.
