Before it goes in
- Apistogramma agassizii needs at least 60 L (16 gal). The smallest size in this library that clears that is the Dennerle Nano Cube 60L.
- Keep 2 or more. Below that it hides, colours down and is far more likely to be picked on.
- It eats shrimp. Cherry Shrimp, Crystal Red Shrimp and Bamboo Shrimp are on the menu.
- It holds at 75–84°F (24–29°C). That shares a window with Betta and Cherry Shrimp, but not with Goldfish and Dojo Loach.
- It can go wrong with Cherry Shrimp and Crystal Red Shrimp — it works in some tanks and not in others, so it is not a combination to buy blind.
- It is semi-aggressive — plan the tank around it rather than adding it to a finished community.
- It digs in the substrate. A freshly planted carpet — Dwarf Hairgrass Mini and Downoi — gets lifted before it roots.
- A group of 2 takes up roughly 41% of what a Dennerle Nano Cube 60L will comfortably hold, so plan the rest of the stock around it.
What tank size does it need?
At least 60 L (16 gal). The smallest size here that clears it is the Dennerle Nano Cube 60L.

What water does it want?
75–84°F (24–29°C), pH 5–7, GH 1–8.
How long does it live?
3–5 years in a tank that suits it. That is how long you are signing up for.
