I have added a Lime Green Wrasse to my tank on Sunday morning (21st March), as I got it into the tank it did the usual Wrasse thing and shot straight under the gravel. It hasn't come out and it is Wednesday evening already - do I dig around and disrupt my gravel in an almost futile excersize in hope to lure it out in hope that it is still alive or could it be dead under the gravel? How long do I leave it alone before I start "hunting" for it? The other fish in my tank are 2 Chromies, 2 Blue Damsels, 1 Violet Angel and 1 Maroon Clown. All of these fish swim about actively and don't seems disturb one another - that ruled out my theory of them being overbearing and keeping the Wrasse underground - but am I mistaken? This is an awesome fish and was 100% healthy when I put it in, my tank is running seemigly OK so there isn't any reason I understand for it to be gone for this long as general reviews talk of it being and easy fish to keep...HELP!!!!
