my crab

[Firstman]

I bought a porcalin crab three weeks ago I only seen it twice whin that week now it disapeared. you think it died? my tank is fairly new well I just about started to place fish and coarls within the last three weeks. everything looks good. before hand I had it cycling for a about a whole year. It is a 90 gal. filled with live rock and a deep sand bed. the alge that is growing is my concern. I have lime green, maroon, bits of purple.

It might have if your tank is still in an initial cycle.

Give more tank details...

Parameter?
Size?
Age?
Refugium?
Live Rock?
Inhabitants?
etc...etc....

More details the better.

Nope I doubt it. I had a friend buy a shaming crab once and it wasn't till we tore the tank apart and moved it did we find it a year later. Set your alarm for 2 in the morning and check it with a dull flash light
