I like to travel, and can't find a reliable bug-sitter. So, I try to be bug-free before I go adventuring. Luckily (through this forum) I've made connections with people (especially local) that can benefit from my "mass extinctions". i think KitKat's "Bring Beer" post was further evidence of that. And how to manage the outcome of massive breeding.
Also, I get kind of finicky. I didn't like the hetero's like some other here did, or my Dead Leaf's. Also, while I LOVED my Gongy's, at about 30 adults it just becomes a burden. Another 30 pop out of an ooth or two, and you just wanna put em ALL up for adoption. For me, there's a breaking point - and I think it's based on volume. 30 Gongy's needed more space than 30 Idolos, because they were so restless. They'd crawl right over each other - even when molting (or KICK each other, as illustrated on KitKat's recent "Green Gongy?" video). But 60 Ghosts were fine (although, even that got to be a little old).
So, I took a few months off, but was still obsessive on the forum. So, probably not a good example of someone leaving the hobby.
