How is everyone going with their Strombs? I bought one 4 weeks ago and it cleaned up about 1/4 of my sand bed and promptly died. I have no idea why and I'm not sure if I should try again or not. My other inverts - eg. brittle stars, turbos, whelks, sponges, fan worms, limpets etc are all breeding and thriving. I floated it in the tank for 15 mins and drip acclimatised it over an hour before releasing it in the tank. Thoughts?
