I am somewhat new to keeping bettas but I have had one for about 3 months now. Anyways, at my local fish store they had two of these bettas kept together, as far as I could tell they were both males. I knew that is a big no no so I decided to purchase one. I named him Tim because he is so small and sickly. I am pretty sure that he has a fungal infection as well as ich. So far all I have done is frequent water changes as well as keeping the water around 80 degrees. So my question to you all is what steps should i take next to get this little guy to prime shape. Hes so active and very happy but I know he is sick. At night he will flash against the plants in his tank. His fins were also in really bad shape when I got him but they seem to be on a rapid come back. I feed tim new life spectrum betta formula pellets and frozen/freeze dried blood worms. He has an enormous appetite and quickly gobbles down everything I put in there. Right now I am keeping him in a 2 gallon spec but I will be getting a five gallon tank for him soon. Here are some pictures of Tim.
In one of the pics you can see white spots on his fin.
