I have a 12 gallon tank, is that normal?
Hey guys, I finally got to measuring my tank today, as I always assumed it was a 15 gallon or 10 gallon. Well, apparently it is neither. According to aqadvisor (and my own calculations) it's a 12 gallon. Is that a normal size? It's 21x11x12. It just seems weird because I've NEVER heard of a 12 gallon tank before.
