I was watching this Youtube video of a Dutch hobbyist with 2 AMAZING reef tanks and saw a fish I have never seen before. Can anyone identify this fish (at 8:18) for me? Thanks!

Will burry any corals on the sand or low on thr rocks. Great fish.I think yes on Engineer Goby. Peaceful great reef fish. Gets pretty big. I’ve seen them 10-12” long. They are diggers though everywhere, anywhere.
The juveniles mimick coral/striped catfish, which are venomous. Kind of a genius evolutionary adaptation.Yep it's an Engineer Goby. Also called a Convict Blenny, which is interesting since they're neither a goby nor a blenny.
They're my favorite fish - I've got a pair now in my 100g. They start off as schooling fish in the open water, and then at come point change their coloration and migrate into the sand. As they grow, their patterns change and evolve.
There are huge schools of them in the wild. Check out this video.
If you visit you local fish store(s), you may have seen them many times and not realized it. I saw them many times before I learned what they were and how they changed when growing into adulthood. I rarely see adults (like in the video posted by the OP), but see juveniles quite often.
Its so crazy to me to think that most of the fish in that school will become "mini eels" and hide amongst the reef. Are the reefs in some areas just FULL of them?Yep it's an Engineer Goby. Also called a Convict Blenny, which is interesting since they're neither a goby nor a blenny.

I'm wondering what the survival rate of those schools are. It could be that many of them are eaten by the time they make it to adulthood. I believe octopi, for example, have tens of thousands of offspring, but only several survive to adulthood.Its so crazy to me to think that most of the fish in that school will become "mini eels" and hide amongst the reef.

Yes, they'll do that. They're not aggressive at all towards other species, but will eat fish that can fit in their mouths.Has anyone that has these Convict Blennies had them eat any of your shrimp or other fish?
