  • Your longest lived inverts?

    I've had a pair of nassarius snails in my tank since 2012. I have no idea how long they're supposed to live but they have outlived all of my other snails by years.

    What's the oldest invert you've ever had?

    We've got a couple hermit crabs that just refuse to die, they have been going strong for at least 3 years. No idea how long those things live but I assumed it was short. They have annihilated just about every snail in the tank but we just can't pull them out as we've grown fond of them
    500 gallon build in slo-mo progress...

        That's impressive. How long do those typically live?

            I've had a halloween urchin for at least 3 yrs, haven't really kept track though could be longer. Also do my snail eating nudibrachs count? Going on 6 plus years with those although I know it's not the same one. Unless a regenerated piece (frag) counts as one in the same.

              I've had a serpent starfish for about 7 years now. I forget I have it until I feed my tank
