I got into this hobby about 8 months ago, and have already owned up to 10 tanks (6 up and running at the moment). I buy a bigger tank, intending to take a smaller one down, then usually can't bear to take the old one down. My husband has had to reinforce the beams/bracing under my 120 gallon cold-water system, and now needs to upgrade our wiring to keep up with all the tanks and chillers.
Currently running ~
1- 4g planted RCS
1- 10g planted RCS
1- 20g planted FW
1- 38g CW marine w/pipefish & shrimp
1- 120g CW marine (former Red Lobster tank)
1- 10g SW
tank for feeder shrimp & amphipods
I also have two more in various stages of the set-up process...
1- 66g CW (new home for the pipefish)
1- 44g tropical FOWLR SW
(will be my first attempt at warm SW
Oh, and we drove 20 hours straight, through 3 states, to pick up the lobster tank. Even the dog is jealous of the time I spend looking/messing with the tanks.
Hmmm, now that I'm writing this all down, I'm thinking that I may need an intervention!
