Family description (Haemulidae)

Fish within in the Grunt family do not often appear in private aquaria, but can be kept in a very large tank under proper conditions. They are predatory fish and mostly live off benthic crustaceans, worms and fish.

There can be a big difference in appearance when the fish is young and fully grown.

This family can divided into two groups: Plectorhinchinae (Sweetlips) and Haemulinae (Grunts).
Aquarists normally find Sweetlips to be the best looking, but they can be difficult to feed and it can be problematic giving them food containing enough nutrition. Grunts are more hardy and quicker to start feeding in aquaria.
It can be a good idea to have live food, Mysis or small live freshwater shrimp, in case these fish don't begin to feed.

One should not acquire these fish with the intention of selling them on when they get bigger. This is, not only because they grow quickly if fed correctly, but also because they are difficult to sell on to domestic buyers.

Sweetlips include the genera of Diagramma and Plectorhinchus.
Grunts include the genera of Anisotremus and Haemulon.
