do you see any problems with these readings? My urchin has lost almost all of his spines
I think my emperor angel might have been picking on him but, he's been in the tank since February of this year without issues. I know my emperor likes to pick on **** but, **** man a urchin?
Sometimes, without warning an urchin will die...it can be being picked on, or not having enough grazing space or for no reason at all...which will make you crazy..
Yea, they can drop their spines because of stress, but can also grow them back. If hes being picked on by a fish he could just drop them and possibly grow em back. Or he may not make it.
Well I think he's toast today. I've had him for over a year. He has plenty to eat in a 125 tank including any coraline algae I grow which was maddening.
