identify critters

Hello my hammer coral is so fluffy and healthy. In the pictures it was just put back in the tank so kinda off ticked off. But as you can see there are big ones ans baby ones crawling around. They are not bothering the coral at all.

Hello I dipped some zoas in Bright-well Aquatics Koral MD cause I found some tiny critters on the rock of the zoas. Not sure what type of pest these are or how to get red of them since the dip did not kill them. Can you help me ID these pest. They have a pair of white antennas. Also found them...

Not sure what exactly these are.

Guys, I’m sorry but after searching high & low..I need help. Below are some pictures of some snails that only come out at night, no bigger than a fresh water assassin snail and similar in shape only orange/brown & black. I’m new to this but very familiar with fresh water. I inherited a 400ltr...

Hi Reef-buds I have a few questions! Mostly identification queries as I'm a noob and I have years of knowledge ahead of me that still needs to be obtained. I'm about at the 5 month mark on my tank. Started with dry rock in the display and live rock in the sump. The system carries about 100...

The gsp has been doing great for a...

Tried to clean what I thought was diatom algae from the sand, but it looks like it may be a worm. This little critter has a bunch of tubes poking out of the sand. Help please!

Found these today coming from one of the pores in my rocks. Not a clue what they are- Theres three of them I can count. Not sure if related but my clowns are acting very skittish (I’ve never seen them behave like this) I’ve added some rocks from the beach that I took from Majorca a few days ago...

Does anyone know what this is? I found this worm just sitting out on the open on a frag tile in the frag tank. Their is now sand and zero live rock. It could have been introduced on a frag plug but I dip everything before it enters this tank. I’m just confused on how I’m just now seeing this...

Checking on my sump and these are starting to pop up. Is it Aiptasia and if so, what's your best suggestion to get rid of?
