I have had several different varieties of asterina stars and I can say 100% I had some that ate my zoas. They would wrap themselves around the polyps and when I would peel them off the zoanthids guts would come with it. They were a very dark grey color on top and white underneath. The normal white or sandy colored ones i have never had an issue with.
@@rudra7615 they seemed specifically attracted to my Utter Chaos for me. It was only when I saw them on my WWC Tazers that I got a harlequin to wipe them out.
I recently discovered a snail i bought from my LFS had one asterina star on it. I thought it was pretty cool, it hasn't harmed any of my corals....so far...I did see it near my zoas but it left them alone.
I've had these in my tank for about 3 years now. I just remove them whenever I can manually if I see them close to the rim of the tank. So far I haven't seen them eat any corals but I i also noticed I barely have any coralline algae. Could be a good or bad thing depending on who you ask. I thought about adding a harlequin shrimp because they look cool but I'm worried my flame hawkfish or bully six line wrasse might go after it.
I used to have a huge one, its a perfect 5 sided star and its a size of a dime, it doesn’t seem to reproduce its the only one i had then it died cuz of cold water
Damnn that’s a lot for a harlequin shrimp 😲 wonder how the price has changed since you commented this. Here in the states I can get one for about $40 USD
@@gregori1o They're still the same. They cost a lot because Australia can't import anything else from other countries. Otherwise people could introduce pests to the barrier reef if they wanted to. Only a few have been found in Australian waters. Things that have high demand and low supply cost a lot.
@@awsome2ish Damn bro that’s crazy. But I understand, and those laws make sense. The Great Barrier Reef must be protected. I’m sure there’s a lot of species in the hobby over there that I’m sure I wouldn’t be able to get here or may cost an arm and a leg. I’m a beginner reefer myself. Going on about 8 months with my first 15g reef tank. And even though I have a local fish store that has a harlequin shrimp for $40. It would probably die in my tank since & recently I’ve only seen a couple asterina starfish pop up! I think they’re kinda cool but hope the starfish don’t become a nuisance. I have a sexy shrimp instead 😃 very cool shrimp indeed 👍🏼
Going on 7/8 years with them in my nano and have never experienced them eating my corals. I was recently at a LFS where they were actually selling Asterina starfish at 25$ a pop. I had to triple take and rub my eyes. I thought I was seeing things. I began to wonder if the debate of good/bad was still raging on as 25$ a Asterina seemed wild to me. It seems the debate still rages on 😂 PS I know there’s 15 or more varieties of Asterina, but for the record. Mine look very similar to the ones you’re showing in the video. Again, I’ve never experienced any issues.
I know this is an old video, I’ve also had a variety of different types of Asterina, I’ve not had any eat Corals. However I have seen them eating in Corals, in my experience it’s only the Colourful Asterina that happen to have a coral appetite.
I was given Asterine starfish in a glass jar. my daughter is delighted. I don't have an aquarium. How long can they live with us? what needs to be done to prevent them from dying if we don’t have an aquarium?
I've had reef tanks for years, i currently have hundreds of these little dudes, and have in each tank I've kept over they years they have been there... they love algae and cover the glass when you dont clean it for a few days... in terms of corals mine have always done well and these stars have never hurt anything in my tank, they just breed a lot and come out at night on the glass and first thing in the morning, with the odd ones staying on the glass in the day...harmless
These destroyed my tank after 5 years. There where more then 10 thousand. It just destroyed my bio balance every so often. Which in turn stressed the coral. Then they ate it. Which Added more starfish because they ate. Wich upset my biobalance. Wich stressed the corals and then they ate some more.... Also they ate the pink and purple alges Left me.with a bare white rock tank. Reef safe he sais... -1
Going on 8 years with them in my tank, never had any issues whatsoever so ever. Sounds like your tank crashed due to something else and you were looking to point the blame at something other than yourself.
Hey March, this is kinda off topic but wanted to ask if you can do a Duncan video since you stated before that it was your favorite. I saw that nice one on Dylan’s tank and topic came to mind
I started seeing them in mine about a year ago. Thoughtbthey were harmless and neat so i left them. Pretty much infested now and they have definitely been earing my zoas and have killed several colonies. Plenty of water tests, perfect water. Established tank of 5 years. Was wondering why my zoas and other stuff have been disappearing. Definitely the stars.
I 100% did the same. i bought 70lbs of live rock from my LFS and i have seen a few stars at first and thought they were cute.. fast forward 2 years and 100x more stars. My bowling ball rock covered in zoas is about 98% gone and only bare rock. I pick off every morning and bought a harlequin shrimp.. cross my fingers
In my experience, they were no problem, but I never had a huge infestation, as long as controlled, I don't see an issue, just maybe a distraction to viewing inside the tank.
There are many species of asterina, and yes, some do eat corals, but most seem to be harmless detritivores. How to differentiate species? good luck lol
A free, multiplying cleanup crew. Yet reef keepers will take them out and buy other clean up crews that won’t reproduce and are less effective at consuming leftovers... Big Brain Moment!
Those torches dont look happy. Im new here but arent they supposed to be flowing upward? My local wholesaler/reefer has many high-end torches and they all branch upward from the wave makers and pumps. These look like they are getting blasted from the top.
Dude They are bad. Don’t give 100% guarantee to everyone based on your experience. Asterina stars started to eat my Zoas. I think they are going for my acans now.
@@waffleman3437 listen to him again around 2:30 mark. He contradicts his in my experience and give a basic guarantee. He say 100% reef safe and you should leave them in your tank. He even implies that they are good for your tank. This would invite and convince a new reefer to actually add them on purpose. Say if they see them on a plug or something. These are just dangerous statements. As you stated and I know as well there are different types/species of these stars and it been said the darker ones are the baddies. He should have said that in his experience he’s not had an issue but there are several reports of some species eating corals. Then say that if you do have them to keep a close eye on them. I’m not hating but with his experience and knowledge he needs to remember that people will look to him for advice and follow it to a T. I hope you understand.
@@rc2300s2r he said from his experience in the beginning so the whole video from there should be seen from his experience stop acting like he should be walking on egg shells i never had a problem with them and i use to grow only zoas never saw one eat any zoas
For me, my zoas were disappearing so knew these bastards had to go. The problem? I can't just get a harlequin to then starve after 2 weeks.. The thing is though, for me they didn't eat every type of zoa, meaning they only go for select ones..and this only happened to my zoas, no other corals.

Harlequin shrimp cost $1000 each here in Australia. And they have only ever been captive bred once here in AUS.

They are not reef safe. There are far, far too many people suggesting otherwise. Your reef many be fine, but others may not be.
