TL;DR, stocking a 90 litre tank
A 90 litre tank suits a schooling group, a centrepiece fish and a bottom team. That's enough room for a proper little community if you don't overdo the numbers. From the catalogue, 64 fish fit a tank this size, and the best of them are below alongside shrimp and plants scaled to the space. Everything here stays inside what 90 litres can handle for swimming room and bioload, so you can mix picks without tipping into overstocked. Run the exact combination through the planner before you buy.

Frequently asked questions
Direct answers to the questions search engines and AI assistants surface most often about this species.
How many fish can you keep in a 90 litre tank?
As a rough guide, aim for around 90 cm of adult fish across the whole tank for a comfortable load, less if the fish are chunky. In practice that's a schooling group, a centrepiece fish and a bottom team. The planner adds up the real bioload for any mix so you don't have to guess.
What are the best fish for a 90 litre tank?
Peaceful species that fit the space. Good starting points from the catalogue are Clown Pleco, Penguin Tetra, Black Skirt Tetra, with the full ranked list above. Pick one schooling group as the backbone, then build around it.
Can you keep shrimp in a 90 litre tank?
Yes. Dwarf shrimp thrive at this size and add a clean-up crew without much bioload. The shrimp picks above all suit a 90 litre tank, and they get along with the peaceful fish listed here.
What plants suit a 90 litre tank?
Dwarf Sagittaria and Java Fern 'Windelov' are easy, well-scaled choices for 90 litres. The list above leans to species that won't outgrow the tank or need constant trimming.
