Awesome! thank you guys for the feed back I really appreciate it. It is a baby pacman but I don't plan on finishing the tank until the begging of next year, so in the meantime I have him in a 5 gallon that he is very comfortable in. The water feature I wanted to do would be very small and wouldn't be deeper and about a 1/2". I know pacs cant swim well so It was mainly going to be for aesthetics. Is this still ok or can I not have any running water in the tank regardless of size or depth
