Does this look like Velvet/Gold Dust disease? Looking at the goldish coloring on the underside of his mouth. I'm not sure if the fins changing to a reddish color are part of the velvet disease or just part of him turning red.
I had a problem with him previously in another thread, at the time thinking it was the new plants or wood that I added. Which could have caused some problems, but now I'm thinking this is a parasitic infection. I have moved him into a hospital tank and he has been in there almost a week now.

Symptoms and Treatment
How has your betta fish's appearance changed?
Goldish coloring under his mouth
How has your betta fish's behavior changed?
He has been more acting and feeling better since moving him into the hospital tank, but still clamping fins in the light.
When did you start noticing the symptoms?
About a week ago
Have you started treating your fish? If so, how?
Yes, Mardels Coppersafe for Ick/Velvet. Also raising the temperature, 50% water change everyday (Should I change to 100%?) Keeping the tank dark.
Does your fish have any history of being ill?
We are thinking he may have had this infection when we first bought him, but because we didn't know what we were looking for and that it was abnormal, that it has progressed. We have only had him for two weeks.
How old is your fish (approximately)?
Just bought him 2 weeks ago from the pet store, so I'm guessing he could be up to 4 or 5 months old?
