hey guys today i woke up and saw that my live rock had little purple and green spots on it and it was also on the shells that are on the bottom of the tank what is this?
also around the spot were the bubbles come from in the tank the rock has become this red ish colour
the last picture is what the "normal" live rock looks like
also if its bad what should i do about it
its a 30g with 2 clowns, 1 anemone, 3turbosnails, 3 electric blue crabs, & 5+ spiroid worms
sorry about the bad focus
all the shells on the ground were white before
