urchin

California Los Angeles local pickup only $30 I have a urchin that needs a home, rainbow frogspawn that I failed to bring out the color (when I bought it it was more colorful), and I can frag some of my cispitularia as well. Images attached

i bought a urchin for my algae problem and its been working well but my clowns have started spawning and wanted to know weather i should separate them for now and the clowns laid on rocks so I cant move the eggs either

I have a small long spine ur him that came on some live rock from the gulf. It’s going to get too large for my tank and I already have a tuxedo urchin. I’m looking for someone yo give him a good home. If you want yo trade for a frag or something that would be cool. I’m in NJ zip is 08551

Hi(: Can I keep different urchins with my long spine urchin?? Thanks!

So I have finally gotten frustrated with my urchin. It first ate on one of my new coral I got and ate some of it off and then recently I got a new mushroom and over night it choice to eat it off the plug and was sitting on top of another mushroom thankfully this one can curler up into the hole...

Hey all! I have a 10+ year old 24 gallon tank at home that is self-sustaining, but has tons of Coralline algae in it. I know some people like it, but I don’t. Can anyone give any tips on what clean up crew to add to attack this? I was thinking a zebra urchin and some trochus snails.

My pincushion urchin has been showing signs of stress for about a week. I did a water change and I think I messed up the salinity and made it too low. He spawned and then stopped moving around the tank. His little grippers and spines would move, he would react when touched, he just would not...

So I have a pincushion urchin who usually is very active. I did a water change a couple days ago and he spawned and now hasn’t moved from his spot for about 2 days. I know he isn’t dead cause his spines are moving and he’s holding onto a shell. He hasn’t dropped any spines either. I just find it...

My tuxedo urchin just made a meal of my Fireworks Clove Polyps. Anyone else ever have this problem?

My sea urchin has been hiding for about a week and looks stressed. I am desperately hoping that he’s not dying, but he doesn’t seem to be improving. Any suggestions on what I can do to save him? Thanks in advance for your help!

Hello, my Fluval Evo 13.5 has been setup since October and has had a lot of algae up until late February. I started out with 3 trochus snails and 3 electric blue legged hermit crabs (I think one or two of these are just blue legged). The trochus lasted about 3 months and then randomly died. I...

Just wanted to share and make you smile, it made me smile. I couldn’t help but share! But here’s my tuxedo urchin (his name is spike) and he’s carrying a little piggy around my tank I even caught him carrying around a toothpick that he found once (I think I had used it to secure something)...

Hello, I have a Fluval Evo 13.5 that has been set up since early October of last year. It has had a big algae problem since the beginning and I’ve had different inverts during this time. Currently, I have a tuxedo urchin and three electric blue hermit crabs. The urchin is pretty small but there...

I have a 125 reef tank with 35 gallon sump with an undulated moray, miniatus grouper, and picasso triggerfish. My cleanup crew consists of a handful of turbo snails (was around 20 now much less because of the triggerfish) and a horshoe crab and chocolate starfish. I have had much luck with many...

Has anyone ever heard of or seen a pincushion urchin where it's spines get stringy? I have 2 of them in my tanks and their spines have always been stiff, but I was over at a friends house and saw that his pincushion still seemed to have all of his spines, but many of them looked almost like hair...

I really would like to get a tuxedo urchin but want to make sure I'm not paying too much! 1 euro=1.09usd=1.46 canadian dollar

Curious if anyone knows the species of this pencil urchin? I mostly want to confirm/deny if it’s a known coral or clam eater?

I have two urchins in my main display, one tuxedo, and one pincushion. My tuxedo roams around the tank, showing up usually in a new location every morning. My pincushion on the other hand always is in the same spot on one of my rocks. I can clearly see that the pincushion has been exploring and...

Tuxedo urchin has what looks like Bryopsis on his back. I have another spot of Bryopsis elsewhere in the tank and have been trying to manually remove. I think the urchin picked up a strand and put it on the back. Anyone else face this issue?

Hi folks. I’m getting super frustrated with my urchin. I cut a handful of frags the other week and have them sitting on a frag rack to heal up but every other night my urchin comes by and pulls the frags out dropping them on top of each other making me have to give the frags yet another week to...

Hi guys! I was wondering to get some help, yesterday I saw this in my pincushion urchin, at first I thought it was just sand that somehow got on him, but when I watched him today the white thing was still on him. I took several pictures, but the one on the post is the best one I got. It would...

Bought this guy a month or so ago. He's just too large for my tank. I have a bunch of tuxedo urchins that are the perfect size and was hoping the Halloween urchin would be about the same size. Nope. He's about 2.5" wide. My tank is 60 gallons. Recommended for larger tanks, or ones with a lot of...

Many of us have heard of a Palytoxin (If you haven’t, read this). Lionfish and urchin toxicity is also pretty widely known about. Corals and anemones have stung people badly enough to cause numbness, pain and scarring. Water and electricity…drip loops people! What are some other risks which...
