I had been keeping some micro brittlestars in a nano tank for a couple of months, and they were doing just fine. Once every couple of nights I'd check in and see one scuttling around looking for a new hiding spot. Then I moved, took the tank with me, did the best I could to keep it from moving as much as possible for the 10 minute drive. It's been 3 months now and I haven't seen a single star yet. What're the chances they all expired? They loved to burrow in the substrate (crushed aragonite sand) so they could just be hiding. Does anyone know if brittlestars can "suffocate" under the substrate? Can they be crushed? With a tank this small, I would've expected the water to get cloudy if they all died and disintegrated.
