Multicolored Urchins are fantastic algae eaters, specifically filamentous algae like hair algae.
Multicolored urchins are relatively small in size and grow to a maximum size of roughly 10cm therefore can be introduced to various sized aquariums.
They come from Indonesia where the temperature ranges from 23 degrees Celsius to 26 degrees.
Multicolored urchins are reef safe.
keep Urchins in stable water parameters where the salinity is in the range of 1.023 to 1.026 specific gravity.
If algae depletes in the aquarium then seaweed can be used to feed them.
