That certainly is interesting. I'm new to the whole Aquarium world and thought that it was 1 inch of fish per Gallon. This gives me a bit more wiggle room for building a community tank. I've had my tank for about a month and things are going alright. I have a 40 Gallon tank with 11 Neons and 3 Endler's...oh and a comet :S I know it's taboo to have a comet with warmer water tanks but he was a rescue. And he's quite happy!
