Hi dose anyone know what the min tank size is for a spiny black urchin full grown
Here is a picture of my urchin eating kelp.Joy 13 spiny black urchins can also be fead dried seaweed my tank is new and glass which leads me to my question what size tank can they be hosed in full size and do they eat diatoms algea
I really don't know the name, It is eating an Asian seaweed called "Fueru Wakame". It is found in the Asians section of most supermarkets. This urchin came in as a hitchhiker at about the size of a pencil eraser. It is now the size, I would say, of a tennis ball.Tincat what urchin is that he looks cool and how big is your tank
