An extremely beautiful fish with a mostly steel blue-gray coloration, they are a hardy and fun fish to keep. The Blue Acara is an old time favorite as they spawn easily and make excellent parents, taking very good care of their fry!

What's in the name? Aequidens means "equal teeth"
pulcher means "beautiful"

The Blue Acara has a more broad forehead than other Acara species and is a bit more courteous than the others as well. Though a more peaceful member of the Cichlid family, the Blue Acara is apt to bully smaller fish. They should be kept with the same size or larger fish.

They like a tank bottom of fine sand and plenty of hiding places among rocks and wood. Plants are appreciated, but the Blue Acara love to dig and can uproot them. Hardy plants such as Sagittaria and Vallisneria are best, and should be potted to protect the roots. They do need frequent water changes as their excretions will cloud the water and promote disease.

The Blue Acara will breed every two weeks on a regular basis if the fry are removed shortly after hatching. They are excellent parents though, and will not harm the fry if you do leave them in the aquarium.
