We have five cats and two dogs, so I spend a lot of time and money in pet stores. Got to watching the fish at one of my favorite
LFS, and talking to the owner (he hasn't said so, but I know he's a fish person). He explained about tank set-up and maintenance, and encouraged me to read everything I could get my hands on. I started a freshwater tank, and before long, my DH mentioned that he'd always wanted a marine tank, but when he talked about it, people told him they were WAY too tricky, so he never started one.
That was six months ago. . . we will soon be starting a 75 gallon marine tank (already have a 55 gallon), and in addition to my two 37 gallon fresh (one community and one goldfish), 20 gallon eartheater cichlid, 10 gallon planted small tetra, and the 37 gallon office tank (which belongs to the office, but I maintain), I'm going to give myself a 20 gallon planted tank in my private office at work.
Did someone mention "addiction?"
P.S. The 37 gallon show tanks witht he Eclipse 3 hoods are wonderful, but not for goldfish ---- too hard to add filtration with that enclosed hood.

Live and learn. . .
