Red Banded Mine Urchin
You will earn 42 Points
TheRed Banded Mine Urchin have a brown, sometimes mottled body with stubby, thick red spines radiating out in all directions. The spines are surrounded by basal plates. Never try to pry it out of a hole, as you will break its spines before it lets go. As it ages, its spines may become covered with coralline and other types of algae. During the day it will seek shelter in the rocks; at night it will come out and forage for food, looking particularly for algae lawns and smaller invertebrates like sea squirts or sponges.
It can be destructive to corals if no other food source is available. It requires an aquarium with multiple hiding places and live rock on which it can graze. The rock formations should be sturdy, since the Red Banded Mine Urchin could dislodge rocks as it moves around the tank.
The Red Banded Mine Urchin is very sensitive to high levels of copper-based medications and will not tolerate high levels of nitrates. If water conditions are poor, it will shed its spines. It is extremely difficult to breed in an aquarium and has no distinguishing characteristics to help differentiate it from its mate.
They should be offered dried seaweed and some meaty foods.
