looks like a type of sea urchin to me but what is it really and is he bad or fine.. there went from none of these things to like 4 or 5

vdituri · 06-23-2008, 09:26 PM

Really? 4 or 5?
Nice.

Someone would probably need a much closer picture to be sure.
Most of the time I've read they eat coralline algae. I had a pencil urchin in a 30g tank and he didn't even make a dent in the coralline.
But I heard of some being coral eaters.
Hope you got a good kind.

Looks like an Urchin to me as well.

travis127 · 06-24-2008, 10:27 AM

yea I had heard that do but I havnt noticed anything change yet so who knows

tippMANn98 · 06-24-2008, 10:40 AM

I do, its an atlantic long spined urchin....i heard they DO eat coralline. i know they eat types of algae. And reproduce Rapidly...you will find all the little babies smaller than a dime....

First, it is not a Atlantic long spined urchin. There are not enough spines or long enough. It is a juv Echinometra sp.

Echinometra viridis
They graze on algae and rarely coralline algae.They are noted for producing many algae free reef patches.

Look to see if there are white rings at the base of the spines.

Echinometra viridis - Google Image Search

Echinometra lu****er
This is a burrowing/rock-bore urchin and feed mostly at night. They usually bore into a calcareous substance and make a burrow to live in during the day. They will remove any coralline algae around there burrow but that is mostly it. They like to eat "drifting" or settled algae. So, they world like to stay in or near their burrow at all times. They are not roamers but may be in a reef tank

They do not have the white ring.

Nobody is being shot down. Where do you get that from ??

tippMANn98 · 06-24-2008, 12:52 PM

now, looking at Echinometra viridis, it doesnt look like either of this species. Im not convinced, when you google Echinometra viridis i get a lot of long spined urchins.

Boomer · 06-24-2008, 12:57 PM

Long spined urchins are Diadema antillarum, also called Hat Pin urchins

Boomer · 06-24-2008, 01:01 PM

Here is the other species, Echinometra lu****er often called Black Urchin

Boomer · 06-24-2008, 01:06 PM

It may also be juvenile, Arbacia punctulata, which it does look more like. Looks like an almsot exact match to me. These eat algae but also sponges, coral polys but are mostly algae grazers and feed at night. Often called Purple-spined Sea Urchin.

tippMANn98 · 06-24-2008, 01:31 PM

#2 looks right, #1 doesnt

Boomer · 06-24-2008, 02:01 PM

Well, 1 & 2 are both the same species

It is just the lighting they use for research at the Hardin Lab. #1 anatomically actually looks even closer. Color is not much of a "thing" in the real world of taxonomy.
