HI 
First of all there is a lot of info circulating on the proper housing for bettas (it's 2 T's, not one) and I am of the opinion that 1 gallons are okay as long as they are kept clean. 2 changes a week is suffice, one 50% water change and one 100% change (also cleaning the decorations). Always add conditioner to tap water when putting the fish back in. In such small bowls you DO NOT need filters, it causes more problems in tanks smaller than 5g anyway.
Bettas are tropical fish and thus need heaters to maintain a temperature of 78-82F. In the summer just placing their tanks in a warm room can be enough but you should really invest in heaters. They're cheap these days for a 10w heater.
Freeze dried worms lack any nutrition and often can cause bloat. If you want to still feed them, soak them in water before feeding to avoid the bloat. But even better is to go buy frozen bloodworms at the pet store. Or daphnia. Bettas LOVE them! Mine will do anything for frozen bloodworms.
Be careful not to overfeed! Have a good pellet for daily feeding (5 days a week), feed frozen bloodworms once a week and fast them for the 7th day. Keep in mind they will eat forever but they should only be fed 3-4 pellets and a couple worms in a meal.
It could be Sheldon has parasites. Check the color of his poop. If it's reddish and in a little ball or clump at the bottom then he's fine. White stringy poop indicates parasites. Maybe his water is too cold, try placing him in a warmer spot until you get a heater. Maybe his water is dirty. Try doing a 100% water change and see if there is any improvement in his behavior. If you look down on him from above, do his scales appear to stick out? Like a pine cone??
DO you have many decorations or gravel in the bowls? Those take away swimming room and thus increases the chances of ammonia taking over the quality of the water.
I would love to see pics.
