From a first glance, it looks like the free swimming stage of a HYDROID. And possibly the beginning of a hydroid invasion. They are close in relation to jellyfish, They will reproduce and reproduce while stinging and taking food from the tank inhabits. These little monsters are exactly what I was scared of getting in my dwarf seahorse tank.

Sorry I know nothing about sw but those little things look bad [moderator edit]. Sorry if they can harm your fish though.

haha well I hope not! I'm expecting them to disappear like most small critters I find every once in awhile. Have you found anything that looks like them?

These little guys kind of look like them but not really, mine all have only 8 arms, hey maybe they are an octopus baby!

Do hydroids always sting?? Cause this one doesn't, i touched it twice, also do they swim? Cause this one does haha I knocked the one off by accident and it swims like a jelly fish or small squid. has a round little clear body with those eight white legs and he pulses himself around, pretty cute!

It's in the medusoid stage if it is a hydroid. Probably hasn't yet develop nematocysts if it is. Also, I wouldn't worry too much about hydroids. I mean, I've had them show up a few times and they always died off before they made much progress. Just keep an eye on em.

 

[0o.Kelsey.o0]

Yah I'm not too worried, I might remove the few I have just to be safe but I'm expecting them to die within a few weeks, pretty neat stuff though!!

Here is a link to a thread which also had the hydro jellys, he got a picture of them in the swimming form.

Because they are stinging, doesn't always mean that you will be able to feel like. Could sting bad enough to hurt the fish and not you. That said I know nothing about those guys, but great pitures. Looks pretty cool!

I took about 20 out of the tank, that's all I could find at the moment. They are super easy to catch, they swim right to the surface. My brother is going to try to keep them alive by feeding them live baby brine haha we will see how that goes.

i was cleaning my tank last week and my galaxea coral stung me with its tentacles it felt like a tiny pinch

You'll soon have thousands. Also if you take them out, they will always come back. It's really insane. (freaks me out)

 

[Sarcothelia]

Not true Dylan. With good filtration and water changes they die off. Good husbandry keeps them in check. I've had them in each and every tank I've ever had and they've never gotten out of control. I actually have a few right now and I couldn't care less

i've never even seen or heard of them taking over a tank.
