Black spiny urchin excreting something....
Just wanted to ask if any of you guys with black spiny sea urchins have ever seen them "excrete" anything...
Lemme explain, we have a black spiny sea urchin that we've had for about 3 months or so. Lately, I have seen him do something that I've never seen before.
In two different spots I noticed him "excreting" these tiny, but perfectly round, things.
Now, I do not know if this is just normal sea urchin "poop" and I just never noticed before...or if he is spawning or what, lol. But yesterday when I checked the tank the small balls he was "pooping" were red in color...
I have no pictures, I'm sorry and I have been doing searches on this all day with no luck. All water parameters are normal, and exactly where they should be.
The funny thing is, I watched him do it...I was watching him move around and then all the sudden these little balls came out from the top of him...not were his tube feet are but out the top and then they fell or "filtered" down through his spines and onto the sandbed....in doing this he left a nice little pile of balls... 8O
So, anyone know anything about this...I'm at a loss.
