Over that last month my pincushion urchin was looking rather sad, I noticed that it dropped a number of spines off the top of its back and I thought it might be because the tanks algae was not enough to keep it going.
I started to supplement it by giving it nori but it still lost spines.
I recently went on a two week vacation and over that time the urchin seems to have grown new spines.
Now I have never kept an urchin before so this is all new to me.
What type of growth cycle do urchins go through and is this common?
Any input is appreciated!!!
Here he is sporting new spines albeit short spines lol
