The catfish, if it has lasted this long should be fine.
For heaters I suggest Azoo brand titanium heaters. I bought mine online, it was pretty cheap and won't break.
As for your worms. It's a sign that you are overfeeding or undercleaning. Don't get a fish to take care of them, just up your tank cleanings.
