I have a long spine urchin in my 55 gal
. Ever since I've put in my new lights there is an abundance of algaes for him to much on. He has been getting a little bigger over the last few weeks.
This is a great thing, means he's healthy and well fed etc... except those spines are... well, long; as his name implies. He, or I should say his spines, take up a good portion of space in the tank. Right now I don't have many other critters in the tank so he's not really taking much away from the tank. But as I stock the tank I'm afraid he'll be taking up too much space.
Now I've noticed from time to time the last inch or two of a spine will catch on a rock or such and break off. Would it be safe to perhaps, prune him from time to time to keep his spines shorter? Perhaps clipping them with finger nail clippers?
Any suggestions or thoghts?
