We have had one for about 5 months now and it is awesome! twice the size he was at the store. we drip acclimated ours for about 45 min it did fine, and we also asked the store where their temp & salinity was kept, and what lighting schedule that it had been used to, also how long it was at their store. it might move around a bit till it finds a place it likes/ ours like mid flow, and a spot on a rock next to a lip by a shelve which is what we understood they favor. they will do better with a clown, it will actually feed the nem. Nems do weird things, like deflating by squeezing out all there water every so often, you will know it is happy when it stays in one place for awhile, Good Luck!
