I've been following this thread with real interest because I was also thinking of getting a Spotted watchman goby or a orange spotted goby. I have crushed coral sub and was wondering if they'd be happy there. The ones I've watched at my lfs seem to do fine with that type sub. Any experiences out there??
Well, I got to tell you, my spotted watchman loves sand... I haven't seen it burrow yet like is mentioned in the threads though...I have enough little crevices between the sand and rock. I have witnessed just today that it is dragging stuff to the opening as if the build a house...Cool!!!!...it eats all types of foods...Brine, pellets, flake, shrimp cut up. When I bought it, they were kept in CC substrate...When I bruought it home and introduced it to it's new home, it started sifting the sand immediately and was not shy at all...Watches every move you make...In my book, if you do not have one, get one....Give it lots of little rubble to play with though..
