Is this a jellyfish?

[Bribri21]

I was looking in my seahorse fry tank and I found two of these jellyfish looking things swimming sucking up the baby brine shrimp. Are these actually jellyfish? How did they get in the tank?!

Whoa! looks like a jelly, very cool

Ahhh... baby box jellyfish... kill them or you'll die!!

Sorry, couldn't resist! I have no idea what they are but they certainly look like jellies. Joking aside though, I would exercise caution until you have ID'd them... just in case

 

[Bribri21]

Yea they look exactly like jelly fish, super tiny. Have no idea how they got in though.

more then likely had a polyp sneak in on some liverock or coral and began to strobulate (produce baby jellyfish). however going off the size and bell shape hes probably been in there for a bit, id keep it in a seperate tank with an airstone and feed it but thats just me.

After some research it turned out to be hydroids. Now using decapped brine shrimp instead of regular dry ones so it won't cause me trouble again

Ill take anymore you find
