so I'm trying to find a good heater for a 10g sorority I'd prefer for it to be adjustable but it is not a must.. I'd like to buy this heater from either petco, petsmart, amazon, or any other website that will ship to the US... please either post a link to the heater or tell me what store you bought it at and the heaters name... I don't really want to spend over $30.00 for the heater but I may consider it for the sake of the fish... So I would like reccommedations for a heater!! I might need some filter reccommedations later but I'm not 100% sure yet!!!
