This was done a couple of times already but, WTH, I'll play.
You might be a monster fish keeper if...
1. Your aquariums have a 'Splash Zone' warning.
2. Your fish eat more shrimp, crab, mussels, etc. than you do.
3. A major water change or new tank setup causes the Water Dept. to come to your house to investigate a leak report. (happened to me)
4. You have more cinderblocks and timbers holding up your tanks than you have holding up your house.
5. You notice, on hamburger helper night, that your fish are enjoying fresh clams, crayfish, fish fillets, etc.
6. The local bait shop starts to wonder why you visit every day.
7. One day, it dawns on you, that the fish occupy more living space on your property than you do.
8. You, instinctively, check the bathtub, before getting in, for anything that may be occupying it while waiting for their tank to be back up.
9. You declare that you need a break from your fish and wind up visiting a public aquarium to relax.
10. Your lfs owners plan their annual vacation around your purchases.
