How much does it cost to have a tank?

[SeaHorse_Fanatic]

It's not the hydro, salt, additives & food that is the expensive part. It's the "oh, let's visit the LFS & just take a look" visits that hurt the wallet. Often find another fish, coral (especially) or invert that you suddenly just need to have. There are very few nice, colourful specimens you can add to your tank for less than $30, so it can get expensive stocking a tank real fast, unless you're patient enough to go the "grow-out your own frags" route.
