I'd like an adjustable heater, but I can't find any and if there are, it's probably too big for my 2 gallon aquarium. I usually put the heater in when it's cold, and take it out when the temp seems good.
Now he doesn't seem to be eating and I'm getting worried. The first 2-3 days he ate pellets, and then he seemed to only eat in the mornings so I bought him bloodworms, put 1 in and he hate it and now he doesn't seem to be eating anything. I tried pellets and bloodworms but he won't eat.
I feel like such a horrible Betta owner...
