Look who I found this morning...
...up near the top of the tank, on his way to "breakfast" (AKA, pieces of plants at the top). I spotted him for the first time a week ago on one of my java fern leaves, but figured I'd never see him again, what with the yoyo around. Just to give you an idea of size, that wide onion plant leaf to the right is about 3/4 of an inch.
1 yoyo loach, 2 polkadot loaches, 6 cherry barbs, 2 turquoise rainbows, 1 chinese algae eater, 2 harlequin rasboras; java fern, java moss, hornwort, Asian ambulia
