what are these?

Anyone able to ID these? First is a fleshy like lump with a red mouth like feature attached to my live rock, idk if it’s always been there but as some of my sea squirts fell off from pesky crabs is when I’ve noticed it. Bellow the bubble tip nem surrounded by the red. I’m unsure about this...

Curious what these are? They look oval shaped and smaller than a grain of rice. Look brownish and move around the glass. Have a V shaped end to the body. Mainly on the glass but probably on the overflow and elsewhere. A good amount of them. Tank has been setup with live sand and live rock from...

I’m assuming that they’re some type of snail but does anyone know what exactly?

So I'm dealing with dinos. What are these and how to I rid them? Also there's got to be a pod of some sort and some thin things. Help to id these please.

First time buying coral. I have it in a quarantine tank. Ive had it 5 days and came home from work today to see this on the side of my coral. Any ideas as to what it is? Dont recall seeing it last night. Not even the brown dots it retracts into when i get close to it with tongs.

Need help identify what this is. Is it some type of worms or possibly eggs? Harmful? What should I do to get rid of it? They are curly white and more with the water flow.

Hello, First time poster here. I'm having trouble identifying a hitchhiker that just showed up on my trochus snail within the past week. No new additions to the tank in a month which is part of my confusion. See attached photo but they look like white fuzzy cones. Any clue what this could be?

Hello everyone, I’ve seen these little white critters all over my system and they are EVERYWHERE. I want to think they’re a type of copepod but I’m not entirely certain. I tried my best to get a good picture. Thanks for any identification!

What zoas are these?? Been trying to find out!

Picked up a new acro at the lfs they didn’t know the name of it, anyone can help me ID it?

Hello everyone! just thought I’d start with water parameters…. They are all good. I have noticed these little lumps on my hammer coral and over the last week they have grown bigger and began to grow what look like small tentacles. Are these new heads growing?!
