If you are talking about posting on here less, I go through periods of posting lots and then not posting at all.
Problem is I get tired of seeing the exact same threads on all the time, I get tired of everyone going with the fads to the next popular fish, and cause I don't follow the fads nobody will comment on my threads or whatever. Sometimes it just feels like the point of the forum is being missed by a lot of people.
Someone asking a genuine question about whether their fish is dying or not, will get 50 views and 1 reply, but some guy showing pictures of his festae/insert generic popular fish here will get 8 pages.
I'm not really bored with my tank cause I chose fish that were small to grow into monsters, so its interesting to watch them grow and interact with eachother. that and I have a job, play a lot of video games, do social things and also keep reptiles. so its not like my life revolves around fish. cutting back can be a good thing, I have one tank and I really don't need any more.
