Overview
The blackspot lampeye is one of the smallest lampeyes, a gentle schooling fish for the middle of a quiet, densely planted nano tank. It takes a little more care than a beginner fish.
Did you know
Some sellers list the blackspot lampeye as the anus spot lampeye. That blunt name is an accurate translation of stigmatopygus, which points to the small dark mark just above the vent.
Caring for the blackspot lampeye
Blackspot lampeyes settle well as a group in 11 gal (40 L) or more, with soft light and gentle flow. A dark substrate, dense fine-leaved planting and calm, well-filtered water bring out the blue eye shine and thin body lines.
Aim for soft to neutral water at 72 to 79°F (22 to 26°C) and a pH of 6.0 to 7.5. Feed very fine foods, such as crushed flake, micro pellets and powdered fry food. Add small live or frozen daphnia and cyclops.
Keep them in a group of ten or more, so they feel secure and stay out in the open. Only the calmest, tiniest tank mates suit them, such as small rasboras or dwarf shrimp. Anything pushy will keep them hidden.
Blackspot lampeyes are continuous plant spawners, depositing a few eggs a day among fine plants or a mop over a long period. Breeding is moderately difficult, and the minute fry need infusoria-sized food before they can take newly hatched brine shrimp.
Good to know
The blackspot lampeye, Poropanchax stigmatopygus, is a true micro fish in the family Procatopodidae. It carries three fine blue lines along each flank.
In the wild
The blackspot lampeye comes from slow, weedy savanna waters of the Chad basin and nearby drainages. It lives in shallow pools and channels that are warmed by the sun and thick with vegetation.

What temperature and pH does a blackspot lampeye need?
A blackspot lampeye is comfortable at 72–79°F (22–26°C) with a pH of 6.0–7.5.
What does a blackspot lampeye eat?
A blackspot lampeye eats very fine foods, such as crushed flake, micro pellets and powdered fry food. It also takes small live or frozen daphnia and cyclops.
How big does a blackspot lampeye get?
An adult blackspot lampeye reaches about 1.2 in (3 cm).
Does a blackspot lampeye need a group?
Yes. A blackspot lampeye is a schooling species and should be kept in a group, not singly.
How does a blackspot lampeye breed?
Blackspot lampeyes deposit a few eggs a day among fine plants or a mop over a long period. Breeding them is moderately difficult, and the minute fry need infusoria-sized food at first.
