INTERVENTION!
It's a great hobby, although I almost hesitate to call fishkeeping a hobby. We have a dog. My daughter has a couple of rabbits and a Ginnie Pig, but they're not hobbies.
Anyway, it's really fun at first, but as one tank leads to another, then another, even when you find the most efficient methods, you can become a slave to the hobby....partial water changes, plant trimming, filter cleaning, live food cultures, join a fish club, create a tropical fish website, on and on... almost always something to do or could be done.
Now I still like it as it's become second nature, but I'm not sure I love it...And I'm not looking for another tank even if I had a spot for it. So for me at least, MTS ran it's course but is now in remission.
