I've been scouring your forums looking for information for proper care of the two bettas I own. Sadly, I currently have them in bowls with no heating, I am however trying to remedy this. I have plans to buy each one a 2.5 gallon tank (As that is the minimum and I have a very limited amount of money.) with real plants.
Anyway, main question. I was wondering what kind of bottom feeder I could add to these tanks (if any) to keep the tank clean? I'm incredibly new to the aquarium world so something low maintenance would be preferred.
