Overview
Blue Panchax (Aplocheilus panchax) is a middle-to-top swimmer for aquariums where the layout leaves enough open swimming space and the water stays stable.
Use these values as planning checks, then make sure the aquarium still has room for behavior, group needs, and calm community fish.
Care requirements
With a Beginner – Intermediate care level, Blue Panchax is approachable, but it still needs stable water, clean substrate, and a well-planned stocking group.
Because it uses the middle to upper part of the aquarium, leave enough open swimming space instead of crowding that part of the aquarium.
With a lifespan of up to 5 years, this is a fish to plan for long term rather than an impulse addition.
Aquarium size and space needs
An aquarium of 80 L or larger can be a reasonable starting point, but it should not be read as permission to overstock.
At up to 8 cm, Blue Panchax stays small, but it still needs room to move, feed, and avoid constant competition.

The pH range for this fish is 6 to 8. That points to a broad freshwater range, but stability is more important than sudden corrections.
The GH range for this fish is 5 to 12 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 middle-to-top swimmer, Blue Panchax is best kept with calm species that will not harass it or dominate the feeding area.
