Pete,
Yes, Polyfilter is the stuff I was thinking of. You're right, it is
expensive but absolutely worth it. I'm not sure what I paid for a small
sheet of it, but I cut it into 1-inch by inch cube or slightly smaller and put
them all in an airtight bag. I put one cube into each 1-liter Pepsi bottle
with one apisto, with about a third or quarter of the bottle filled with water
and one leaf (from litter) for the fish to hide under. Obviously, no
oxygen. The fish were fine for more than a week and if the Polyfilter
turned dark brown, I replaced it with a fresh cube. I'd take two 100-quart
Coleman cooler down with me and these hold a LOT of Pepsi bottles. This
works really well for killies too. If you are going to
ship Apistos across the country, this technique is certainly worth looking
into.
