Molluscs

Creatures with shells on their backs and others without, are included in this section. Some are easy to keep, while others are next to impossible. Some are destructive while others have housekeeping properties. So there is much variety within the scope of this section.

Giant Blue Clam (tridacna maxima)

The Giant Blue Clam (tridacna maxima) is often available these days from clam farms, where they are raised free of the retaining rock that normally encases them on the reef. Being filter feeders it is often necessary to introduce some particulate food into their immediate vicinity for long-term success.

Blue-ringed Octopus (hapalochlaena maculosa)

The Blue-ringed Octopus (hapalochlaena maculosa) is not generally available to the aquarium market in view of its potentially lethal bite. But we show it here as an example of what the small octopus species look like. The small octopus we do have from time to time is less colourful, but has attractive, elegant, and proportionately longer arms.
