How many Urchins can a 150 gal tank with 180 lbs of LR support? Other than the urchins I only have one snail, one general Starfish, and one hermit.
Some time back I put 2 long spined and one pincushion in my tank and I have recently found several small long spined urchins that must have hitchhiked on my rock. If 6 or 7 is too many to have then I would rather keep the smaller fellas and take the big guys back.
Any thoughts?
