Hello!
I have 2 goldfish in a 30 gallon (I know, too small) tank. They are usually in the outdoors for 6-7 months in a semi-large pond. We have a small, 10 gallon tetra whisper running as the only filtration (besides plants). It was the only filter we had. Surprising, they haven't died yet. But the thing is, a friend doesn't want their 46 gallon bow front aquarium anymore with 3 goldfish and a sword tail. I want to do something else with the tank, so the new fish would go somewhere else. The only option would be the pond and the 30 gallon tank for the winter months. I know the filter is not going to work at ALL, but I don't know what to get. HOB are not an option because they would not fit on the rim (I tried, a lot). The only options left are canister filters or a really good internal (or mix). I don't know what to do. I want to stay in the budget zone, which is 100 dollars or less.
