My husband is the one who started out with the obsession, but he almost seemed to get bored of it after we got our 55 gallon stocked.... Then I took over all the water changes, re did the tank, got a 5 gallon tank, decorated it, got a betta... then bought a 46 gallon because I really want to do a planted tropical community tank.
He semi-supports me... He'll give me input and stuff, but he complains we are starting to run out of room in our apartment... Its a small two bedroom and we have our 55 gallon, a 40 gallon (bearded dragon) a 46 gallon bowfront, and a 5 gallon... Plus two cats and a toddler.
