p.s he opens his fins when i feed him bloodworm treats.
You should invest in a thermometer to get the temperature of the water. Bettas need to be between 76-82 degrees. Somewhere right in the middle is a good spot. For example mine is usually at 79-80.
What size tank do you have?
Are the fins clamped only when he's still? They can rest like this. My Norman sometimes chills at the bottom of the tank or in a plant like this, but when he swims around and when I interact with him his fins are open.
I think if you have some kind of multi day feeder in there take it out and do a water change. It might be polluting your water. People here generally advise against multi day feeders. Only feed what they will eat in a couple minutes and take any extra out before it rots and makes your fish sick.
At least, if nothing else, get a thetmometer to check the temperature. Maybe it's in the range for bettas and will be fine while you look for a heater that's in your price range. You can find cheaper ones online sometimes. But at least find out what tje water temperature is. You may have to warm up the room he's in if the temperature is too low. Temperature is important, cold water really harms your fish amd will eventually kill them if it's drastically low. This could be a cause of the clamping, along with the automatic feeder. I think the pet store owner told you wrong. We're just trying to help.
