I have a bunch of Malaysian Trumpet Snails for trade.
(I'll replace google image tomorrow if absolutely needed, but they look like this.)
Get these to turn your soil so there's no gas pockets, and less detritus. They are most active in the dark.
Hit me up in pm on your trade offers.
I'm looking for Subwassertang (round pellia) and shrimp. (No neos, please. Ugh, that hurts. LOL)
