Hello, I recently introduced a fish to my DT that was sick and killed my white tail bristle tooth tangs before I could figure out what it was. I started up a 20 gallon QT tank because I knew it was an emergency at this point. I put my Flame Angel, Two clownfish, and a damsel in the QT. Using...

Ive been having a small outbreak of a Dinoflagellates like algae. Its brown and looks slimy, and as it gets bigger/ longer it producers a bubble at the tip. It grows very fast and I end up siphoning the visible chunks every few days so it doesn't grow over the corals. It seems to irritate most...

Hi, I’ve just had another read through the helpful threads on critters and hitchhikers. I think the closest I got to a potential ID is Amphipod. Is this right? I’m hoping he’s a friendly resident as he’s scarpered off since researching! I’ve attached a video too. They seem to work for some...

Heyy guys, i need some help identifying what is on my sandbed. I have attached some picture od some sand grains under the digital microscope. Especially the red stuff if anyone knows please help id.

I posted this on a FB group, but wanted to share here as well to get your expert opinion. Any idea what's this "thing" on my toadstool? Someone on FB said barnacle. I Google'd it and it looks like it but not sure (I had no idea what a barnacle was until 5 minutes ago :p) What do you guys...

I observed this critter in one of my store tanks for about two months. I have unfortunately moved and never managed to get better photography so I'm afraid this will have to do. I'm just fascinated by them because I have not been able to ID them for months! I have collected a couple other posts...

Hello ! I’m brand spankin new to this forum this will be my first post . Hope all is doing well . I have a question in regards to this “thing” that caught my attention in my tank today . I noticed a clam like thing growing on my live rock along with tiny little ones near by . My tank...

Found this picture of a beautiful fish that looks to be a type of blenny or goby. Anyone ever seen one before or know what it is?

I have had the frog spawn and the torch for 2-3 weeks. I have dipped them 4 times now in coral RX and still keep finding theses lil bugs crawling on them. Is this something I should be concerned.

Hi! A newbie hobbyist here. These white, fuzz/fine hair like algae appeared practically overnight on my rocks. Would appreciate some help IDing it. The tank (Fluval Evo 13.5G) finished cycling three months ago. current live stock: A RBTA A zoa frag An emerald crab A peppermint shrimp 2...

Saw this thing on my LOBO this morning. Any idea what it is???

I just got a Trumpet/Candycane frag and when I dipped it I saw this little guy sitting inside the tissue of the coral. I got him out pretty easily and got him in some clean saltwater until I figured out if he was good or bad. The only thing is I have absolutely no clue what kind of crab it is...

Have no idea what this is. Anyone have an idea?

Got this coral from a fellow reefer. Can you help ID? Is this a Sun God Psammacora or something else?

Hi, wondering what these tiny microbes are in my reef tank, viewed here through a hand lens. They have a distinctive shape. Thanks!

About 6 months ago I noticed one of these little guys. Now, I think I've counted 8. They're really small. The biggest one I've seen so far is maybe the size of pea. I havent noticed any issues among the coral or fish. But I reeeeeeaaally wanna know what it is!!! In the 6 months of having these...

I've found this little weird crawling bug things in my tank. I have no idea what they are so I could use some help! They seem to have little legs and antennae. They're super tiny so the pictures aren't the best but I'll find a way to make them more clear!

See the yelllowish sponge looking things and undernieth that it’s clear white and even purple

I need to find the names of the two coral in my tank for a website I'm making. See picture below for reference. Thanks for your help!

Please tell me what in the world these two are.. Pay close attention to video.. You will see it close as my finger gets closer.. And the pic I'm trying to figure out the red thing?
