So here is what happened. My I accidentally gave the "betta virus" to my boyfriend and he went and got a halfmoon, a 5 gal tanks, a heater, etc. The heater and the decoration were from walmart, and I felt that the heater wasnt really working because the water felt cold to the touch. It is my personal opinion that the perfect water temp is when you cant even tell your finger is in the water because it is the same temp as the air. When i checked the fish this morning, he had a chunk of his top fin missing and I concluded that, since it was fine yesterday, either he chewed it or his decoration tore it. Turns out that the decoration was Penn-Plax so we got him a new one (verrrry careful to check for sharp edges) and returned the heater. We only have one pet store in our town and they don't get regular shipments, so we ended up having to settle for a 50w heater. I expressed my concerns about this to the store owner and he said it was fine as long as we kept it on low and checked the water temp often. The heater is a 50w 6" Elite Radiant. It has a temp control knob and is not submerseable. It has a pilot light (which confuses me a little). This is the heater http://www.amazon.com/Elite-Thermost.../dp/B0002AQF8O
