Best Guppy Companions for this Tank
- Mollies & Platies: Very hardy, swim all levels, visible from above, and thrive in the hard water natural to concrete setups.
- Endler’s Livebearers: Fantastic top-view colors, highly active, and thrive alongside guppies.
- Medaka (Japanese Ricefish): Exceptionally hardy outdoor fish bred specifically to be viewed from above.
- Zebra / Leopard Danios: Very active top-swimmers. The 3ft diameter gives them plenty of room to dart around without harassing guppies.
- Bristlenose Pleco: Great for controlling algae on the concrete walls.
- Corydoras Catfish: Sift through the bottom substrate and keep food waste down.
- Snails (Nerite, Apple/Mystery): Keep the concrete sides clean without threatening guppy fry.
