Octopus spp. - Cuvier, 1797

These are crafty, strong escape artists and need a tight-fitting lid. Janine Cairns-Michael

[edit] Overview

Octopuses need at least one hiding space or den; large barnacle shells or pieces of PVC pipe work well. They are nocturnal. The three most common species in the hobby are Octopus bimaculatus (Eastern Pacific), Octopus briareus and Octopus joubini (Caribbean). Octopus bimaculatus is distinguished from Octopus briareus by the presence of two large, whitish “eyespots” on the web at the base of the arms, in front of and below the eyes.

Family: Octopodidae

Other common name(s):

Native range:

Maximum length: 20 cm (8 in)

Minimum aquarium size: 76 L (20 gal)

Lighting: Diurnal cycle necessary. Dim to moderate lighting.

Water: Marine 24 °C (297 K, 75 °F) - 28 °C (301 K, 82 °F)

[edit] Feeding

Prefer live foods (small marine fishes or shrimps).

[edit] Aquarium Compatibility

Predators on crustaceans, perhaps fishes. Not suitable for reef tanks.

[edit] Special Care

Octopuses must have very pure, highly oxygenated water. They cannot go very long without live food: do not attempt to keep one unless you have a ready supply of live crabs or small bait fish. These messy feeders liberate a lot of urine after feeding, so a good skimmer is a must.
