My two newer fish are doing well in quarantine. I adopted a kuhli loach from a guy who had to move (this is the last fish I'll take into my thirty-eight gal- it's at full stocking level now). It's a striped one like Albert- with the dark bands running together and mottled appearance on the stomach. But more yellow base color (I wonder sometimes if Albert is chronically unwell and thus pale, but he is getting thick in girth, so not too concerned).
This new fish hid for a day, then started coming out regularly when I dropped in food- betta flake and pellet, sinking hikari loach wafer, crushed shrimp pellet. It's cute to see it poke its head out from under the leaf litter, and slide in curves on its belly across the glass bottom.
