Yep, but the Lambis species are generally not as easy to keep alive as some of the other strombids. You might have to try to grow various species of macroalgae to supplement the diatom/microalgae diet? I would be interested to know how successful you are in keeping one. Most Lambis species don't live more than 4 or 5 years in the wild, although L. arthritica might live a little longer since it's larger with a heavier shell.
