Tropical Abalone – LiveAquaria
The shell of the Abalones of the Haliotis genus is tear-shaped and has an irridescent interior. The mantle has numerous papillae. It is generally nocturnal, finding refuge in holes or crevices in the rocks or coral during the day, and coming out to forage at night, using its foot to glide over the substrate and coral rubble. The foot attaches very firmly, so use extreme caution if attempting to remove it from glass or rocks.
The Abalone is useful in reef aquariums because it eats algae. The Abalone has a calcium-based shell which protects it from most predators, but requires the maintenance of proper calcium levels in the water for proper growth. Nitrates should be kept at low levels and it should never be exposed to copper-based medications.

What kind of water conditions does the Abalone require?
It requires stable calcium levels for shell health and low nitrate levels. It should never be exposed to copper-based medications.
How should I handle the Abalone if I need to move it?
The foot of the Abalone attaches very firmly to surfaces. Extreme caution is required when attempting to remove it from glass or rocks to avoid injury.

The Abalone has been a great addition to my reef tank. It actively grazes on algae and doesn’t disturb the coral. I’ve maintained low nitrates and stable calcium levels, which has helped it grow steadily. It’s peaceful and stays hidden during the day, only coming out at night.

I noticed it’s very active at night and helps keep algae under control. I had to be careful when setting up the tank to provide hiding spots. The shell is beautiful with a soft iridescent sheen. I keep calcium levels monitored and avoid copper treatments.

This species is a quiet, effective algae eater. It’s adapted well to my tank conditions. I appreciate that it doesn’t compete with corals and stays in its crevices during the day. The foot attachment is strong, so I didn’t have any issues with it sticking to the glass.
