Swimming button mushroom?

Def no idea.

Apologies for soft focus and clarity. Galaxy 5 and water change day.

Some sort of free swimmer? Looks like a tiny Jelly. Have breeding snails, but never seen this. Also added Berghia a month back.

Might be a tiny jellyfish or another hydrozoan... that's pretty cool.

Jellyfish nothing to worry about!

I had something similar. Here is a video before they were released free swimming.


I thought they were upside down jellyfish, because they keep swimming down towards sand bed. But I'm not very sure now.

That is the ephyra stage of an upside down jellyfish. I have hundreds of the polyp stage of the jellyfish in the parts of my tank that aren't visible from the front or sides of the tank. I get ephyra swimming all the time (although I boticed that they have been showing up less lately, which I assume has something to do with the change in seasons). I have yet to be able to raise one to full adulthood. But someday....

Thank you both.

In appreciation, the guys and I went in together and got you this gift @El_Guapo13
