The listed lifespan is up to 10 years.
Water parameters
The temperature range for this fish is 23–27 °C, which fits many tropical freshwater aquariums. Choose other fish with overlapping temperature needs.
The pH range for this fish is 6–7.5. That points to slightly acidic to neutral water, but stability is more important than sudden corrections.
The GH range for this fish is 1–18 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.
Temperament and compatibility
As a peaceful bottom-to-middle swimmer, Threespot Headstander is best kept with calm species that will not harass it or dominate the feeding area.
Because this fish uses the lower to middle part of the aquarium, compatibility is easier when other fish are not all competing for the same swimming space.
Swimming zone and behavior
This fish uses the lower to middle part of the aquarium, so leave enough open substrate area for movement and feeding.
Feeding
As an omnivore, Threespot Headstander should receive a varied diet rather than one repeated food type.
Because it feeds near the bottom, make sure food reaches the substrate and is not completely taken by faster fish in the open water.
Before adding this fish
- Make sure the bottom area has enough open substrate for a group.
- Choose other fish with overlapping temperature needs.
- Keep pH stable within the listed range instead of making sudden corrections.
- Avoid aggressive or highly competitive fish.
- Offer a varied diet suitable for an omnivorous bottom-dwelling fish.
