🍽️ Feeding Habits

Aphyosemion P82 are micropredators with a strong preference for live or frozen foods.

Ideal diet:

• Baby brine shrimp

• Daphnia, vinegar eels, microworms

• Frozen bloodworms or cyclops

• Soft micro pellets or powdered food

• Finely crushed flakes (supplementary)

Feed 1–2 times daily, ensuring food reaches the mid- to upper-water column where they naturally feed.

🧼 Care and Maintenance

• Weekly water changes (15–25%)

• Use soft, dechlorinated water with stable parameters

• Keep a tight-fitting lid—killifish are known jumpers

• Provide lots of cover with plants and low lighting

• Include spawning mops or moss for potential breeding

Steel Blue Killifish are annual spawners in the wild, but in aquariums, they can be bred year-round under stable conditions.
