I've done some work on the pickle jar since posting but yes!
1 gallon pickle jar - added an amazon sword (already regret it due to the size but I'm just gonna see what happens) added more gravel and a fert tab, reworked the airline so there's less flow, and replanted the piece of pearlweed that isn't visible at this angle. Ignore the clump of hair algae up top I need to put it through reverse resperation to try and salvage some of the plant matter but there's so many baby snails in it I haven't had the heart yet. Home to a random number of MTS, Ramshorn, and bladder snails.
1 gallon Walstad cookie jar - The pearlweed has been taking off and I've had to thin out the duckweed several times. Home to a pair of MTS and at least a pair of bladder snails.
