Never ceases to amaze me at what new critters show up in tank periodically even after tank up several years.
Up early and just as lights turning on I noticed a blackish "blob" on sand in front of tank...
Running for camera, I got these pics...
Would guess about 4" long.
Quickly disappeared into rocks once light turned on...
May explain complete disappearance of hydroid plague I have been "blessed" with for ages...
(still think there is a pistol shrimp in there that I have never seen, but often heard)
