my pinchushion urchin moved about 7 inches the other day and it lost its spins along the way why is this? it is time for my water change my levels are am .25 ph 8.0 na 9 ni 0. plz help
I have a pincushin urchin and I have read that they lose their spines because of poor water quality. You should do a water change, your ammonia should be zero.
i chaged my water and now my am is 0 but he continued to loose all of his quils he is still eating how ever. tho he has not moved. help!!! will he be normal again?
