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.

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.

Usually found hiding under mopani wood, this algae eater has endured six tank moves without missing a beat. I only have 1, currently serving as primary cleaner of the 75-gallon tank.

The newest introduction to my tanks, these brightly-colored mid-water fish tend to school together with the pymgy corydoras catfish. I have 10 of them in the 36-gallon tank.

The tireless custodians of my tanks, I started with 10 of them from Joe's Shrimp Shack in 2022, and now have at least 500 spanning all three tanks.

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.

Often found snuggled up in the Süsswassertang, six of these smaller cousins of the albino cory cats live in the 36-gallon tank, sometimes going days without being visible.

Eerily transparent, 6 of these mid-water swimmers like to hide under the mopani wood in the 75-gallon tank. However, they quickly make themselves known whenever any food touches the surface.

The very first fish I bought, back in 2022. Active mid-water swimmers, often found schooling together with the zebra danios. I currently have four of these in the 75-gallon tank.

Absolute goofball noodles. Nominally nocturnal but fairly common to see them playing around throughout the day. Huge fans of Hikari's Sinking Carnivore Pellets. Approximately 12 of these live in the 75-gallon tank.

Prone to dying on introduction to new tanks, and difficult to introduce to new foods. I currently have three of these shy algae eaters, with two in the 75-gallon tank and one in the 55-gallon.

One of my favorite loaches, along with the kuhlis. 5 of them can often be found clinging to mopani wood or the glass of the 36-gallon tank.

The spiciest resident of any of my tanks, this invasive crustacean rules over the 55-gallon tank, hiding under the mopani wood during the day and scavenging at night.

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

Another algae eater, these unassuming snails help keep the glass clean (except for the eggs they lay everywhere). There are a few in both the 75-gallon and the 55-gallon tanks.
