Amano shrimp (Caridina multidentata)

Distant cousins of the neocaridinas, these shrimp are much larger but otherwise act very similarly. However, they can't reproduce in fresh water, so I only have a few of them in the 55-gallon tank.

Black molly (Poecilia sphenops)

The first (and last) livebearing fish I've raised. I started with 3, at one point had 30, and now I'm back to 4. The numbers have remained steady since I moved them into a shared tank with a crayfish and few hiding spots.

Albino corydoras catfish (Corydoras aeneus)

Voracious bottom-feeders, they seem to love lounging on the bottom of the tank with the kuhli loaches. Almost as hungry for Sinking Carnivore Wafers as the loaches, too! I currently have 8 or so of these little guys in the 75-gallon tank.

Zebra danio (Danio rerio)

Close friends with the harlequin rasboras, 6 of these can usually be found swimming near the top of the 75-gallon tank.
