Ok so my decorator crab is a nutball. He has basically trimmed off all the Algae and slapped it all over his body. So basically he is the only thing in the tank with algae on him lol. At least we know where he is at now. HA HA HA.
My decorator crab did the same thing, I saw this walking bush and said to my wife what the heck is that. Then I realized it was the crab, then last week I watched him pluck everthing off and he stuck new purple seeweed on him.... goofy..
