i have 55 gallon tank and early on we got a fiddler crab. love him he did this weird little ymca dance and was very active. ever couple days he would retreat to the floating plants (which i know is normal) and hang out for a few hours. since we liked him so much i researched them and spoke with the fish store and decided to get another one (female). since we brought her in now niether crab has come down from the floating plants, i can honestly say i havn't seen them in the water for weeks. does anyone know why this may be? any insight would be very appreciated thx L
