I introduced a Black Spiny Urchin to my tank yesterday, and this morning I find it breakfasting on the yellow damsel! No big loss, but is this urchin hazardous to my other inhabitants? My guess is the damsel spiked itself last night. I know urchins are docile, mobile and nocturnal and algae-eaters. Might just be a coincidental thing.
Any thoughts anybody?
