Electric Blue Ahli
Sciaenochromis fryeri
Cichlidae
About
The electric blue ahli is a striking open-water haplochromine endemic to the rocky coasts of Lake Malawi, where dominant males glow an intense metallic blue while females and subordinate males stay a plain silvery-grey. A committed piscivore, in the wild it hunts the young of other cichlids around rock mounds, so it must never share a tank with fish small enough to swallow. Robust and only moderately aggressive for a Malawi cichlid, it is best kept as a harem in a spacious, hard-water rock-and-sand setup rather than a soft-water community.
Care
Keep in hard, alkaline water (pH 7.8-8.4, high GH/KH) at 25-27 C in a tank of 280 L or more, at least 150 cm long, with open sand and rock caves. Best as a harem of one male to three or more females in a dedicated Malawi setup; give it robust, similarly sized tankmates and a secure lid.
Diet
Piscivorous carnivore that eats small fish and fry; feed a quality cichlid pellet plus frozen mysis, brine shrimp and krill. Avoid mammal meat and go easy on bloodworms to reduce the risk of Malawi bloat.

Telling males from females
What works for this species, most reliable first.
- Extended finsStrong · from about 8 months, and later in a suppressed male
On many cichlids and killifish the male's dorsal and anal fins draw out into trailing points as he matures, while the female's stay rounded.
- VentingA hint only · only on a mature fish, easiest when she is in breeding condition
The method breeders use when the answer has to be right. Hold the fish upside down in a wet hand or soft net and look at the two openings ahead of the anal fin. The forward one is the anus; the one behind it is what you are reading.
- Adult sizeA hint only · only across animals of the same age
In many cichlids, catfish and loaches one sex simply grows larger — usually the male, though there are well-known reversals.

Frequently asked questions
- What tank size does a Electric Blue Ahli need?
- A Electric Blue Ahli needs an aquarium of at least 280 litres (74 US gallons) with a footprint at least 150 cm (59.1 in) long — for this species, swimming length matters as much as raw volume.
- What water parameters does a Electric Blue Ahli need?
- Electric Blue Ahli does best at 24–28 °C (75.2–82.4 °F), pH 7.6–8.8 and a general hardness of 10–25 °dGH.
- What group size does a Electric Blue Ahli need?
- Electric Blue Ahli is a social species — keep a group of at least 4 so natural behaviour emerges and stress stays low.
- Is the Electric Blue Ahli suitable for beginners?
- Electric Blue Ahli sits in the middle of the difficulty scale — manageable for a careful beginner who has done the reading, but it has specific needs worth researching first.
