The weird stuff in my tank

[avilamillar]

Hey I have found this in my tank and took some pictures for you to see it. I'll appreciate if someone could help me with the ID.

Jellyfish? Cassiopeia Andromeda?



Blue Caulerpa?





Some kind of Coral?



Baby snails? they're tinny. Collinista? Nerites(I've nerites' eggs everywhere)

They only come out at night and stay on the lower part of the glass that I dont clean and on the shells of my clams







This is a bigger one(still pretty small) Collinista?



Also saw this guy releasing eggs/sperm last night. Nassarius?



Thanks

I thought those snails were a stromella or something like that. Used to have a lot, now not so much.

As far as the blue algae. Never seen the color before. You're not missing a parakeet are ya?

[avilamillar]

No I'm not missing a parekeet hahaha. It's a weird color right?

Are you referring to the snail on the las pic or to the tinny ones? I do have lots of stomatella so the baby ones might be stomatella but the other im almost sure is a Nassarius

[allan]

Yes, the tiny ones. The last is a nassarius. They live under the sand but come out when you feed.

I would say: exceptionally beautiful blue-green Brypsis and the little white snails are Collonista.

[grouch]

Ditto on the Bryopsis. That stuff will spead like crazy.

[avilamillar]

There are a few that kind of look like small stomatellas, but most look like Collonista. are they all going to survive? I have 100+ baby collinista

On that side filter is the only place I have found the bryopsis. Should I just pull it out? I dont want it to take over my tank :S

Thanks

I'd take it out. It's pretty but it can make you very sad when you have it everywhere.

I have those Collonistas too. There's always grown ones and gazillions of babies. I never get gazillions of grown ones. Not sure what happens to them in between.

No idea what that polyp coral is. Can you get some more photos of it? More close ups and a brief description of it's location in the tank, etc.

I am not 100% sure it is bryopsis... but I'm looking on my phone and probably missing details. Check some comparisons with different types of feather caulerpa, and see if anything eats it before committing to a full on war against bryopsis. Pruning is good, but make sure not to let fragments loose that could spread if it is an evasive algae like bryopsis. Anything you can remove, dip with H2O2. If you do a search on MAAST you will find several threads on the subject

Go ahead a bookmark this link. It will come in hand time and time again.

The algae looks like Bryopsis. As a precaution, I would carefully remove it.
