Electric Blue Hap Tank Setup
Give them at least 280 litres (74 US gallons). Cichlids are territorial and produce plenty of waste, so strong filtration and some rocks or wood to break up sight lines both help. Aim for 73-82°F and a pH around 7.5-8.5. They reach about 18 cm as adults, so don't be misled by the small juveniles sold in stores.
What Do Electric Blue Haps Eat?
They're meat-eaters, so feed good-quality frozen or gel foods rather than relying on generic flake. Go easy on portions - leftover protein fouls the water faster than plant foods do.
Electric Blue Hap Tank Mates
Electric Blue Hap; piscivore that hunts small fish. Keep with robust Malawi haps/peacocks. The Electric Blue Hap is aggressive, which is the first thing to weigh up when you choose tank mates. It's a known fin-nipper, so avoid bettas, guppies, and other slow, long-finned fish. It's predatory, so anything small enough to fit in its mouth will be treated as food rather than a companion. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Electric Blue Haps Good for Beginners?
Doable once you test water regularly and catch problems before fish look sick. If this is your first tank, pick something more forgiving and come back later.
Electric Blue Hap - frequently asked questions
What size tank do Electric Blue Haps need?
Electric Blue Haps need a tank of at least 280 litres (74 US gallons). A bigger tank is always easier to keep stable, and gives them more room to settle in and behave naturally.
What water parameters do Electric Blue Haps need?
Keep them at 73-82°F with a pH of 7.5-8.5, steady rather than chased to an exact figure. In a cycled tank, ammonia and nitrite should both read 0 ppm, with nitrate kept low through regular water changes.
What do Electric Blue Haps eat?
Electric Blue Haps are meat-eaters. Feed good-quality frozen or gel foods rather than relying on generic flake, and don't overfeed. Feed small amounts once or twice a day, and remove anything they don't eat.
Are Electric Blue Haps good for beginners?
Electric Blue Haps are best for keepers with a little experience. They are manageable once you test water regularly and catch problems early; a complete beginner may prefer something more forgiving first.
Common mistakes with Electric Blue Haps
- Underestimating tank size - the minimum footprint is 280 litres (74 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
- Mixing with long-finned fish - Electric Blue Haps will nip at bettas, angelfish, and other fish with flowing fins, causing stress and infection risk.
