I'm asking this question because this seems to be such a big part of this hobby! I mean, it's really exciting when you get to set up a new tank, decorate, decide on fish. But after that tank is up and running and stocked....what keeps everyone interested? I find myself really taking my time setting up my 40 gallon....because the setting up and deciding part is my favourite part. I don't mind the maintenance, etc......but who really enjoys doing the maintenance? After your tank is fully stocked, what does everyone do? I always find myself wanting to set up another tank after one is complete! I'm just curious, I know what keeps me interested but I'm wondering what keeps everyone else interested.
