Suppose it depends on scale. At most I ever have is a single spawn to move on, so might take care of half the garbage bill every few months, or a couple cans of food and a pack of frozen bloodworms is just as good to me.
This is provided the local doesn't already have what I have. Right now I could stand to thin out the Kribs, they look great, better than the ones at the shop, which have not sold for months, still - they don't really want any. They would let me trade a few of mine for one of theirs for genetic diversity...but mine look better. If they didn't have any. . .
