You've asked the kid at the pizza shop to save you some of the one gallon jars that the yellow peppers come in cause they would be great for hatching some angel eggs.
or...
You've gone around the block to make another pass by some house because "omg was that a huge planted tank I just saw in that front window?"
or...
Your kids are getting really sick of you asking "are you sure you wouldn't like an aquarium for your birthday this year?"
You might have MTS if:
you have gone from 1 to 10 tanks in a year...and knowing from the beginning, that a python wont fit your sink and the OP lives too far away to figure if the shower attachment works for her
