Over the last 2 weeks, I have noticed an issue with several of my torch corals. The tentacles near the mouths appear to be shrinking and curling inwards (toward the mouth). I have attached several images with this issue. This issue happened to me once before, and the only issue with my tank at...

Need help identifying this Coral and the problem with it and how to treat.

My cyphastrea started developing these white spots a few days ago and they have spread. Is it tissue recession or is there something else going on? Going to do a H20 change as soon as I can get the salt tomorrow but so far all my chem looks good. Any ideas? https://ibb.co/DC0Tbkg

My new Polyps coral is covered with some white stuff, and it smell like something rotten, the rotten part of the coral are in brown color under the white stuff, anyone know how can I do for it?

Our coral/invert permanent QT has gone through some changes recently. It started around the time of a power outage we weren’t prepared for lasting about 12 hours. Temp only got down to 74 and everything seemed to be doing ok initially. We also added in a new order of snails and crabs around this...

Hello, I got a frogspawn 2 weeks ago and I observed recently that the tissue near the base is getting white, is it normal? I am worried that maybe it’s a disease, or it’s not happy, or maybe my shrimp is biting it. My parameters are normal. any help is much appreciated

This is the current state of one side of my poor trachy. I got him about 2 weeks ago and on the day after successfully acclimating, inflated like a balloon, ever since though he's been pretty tight to his skeleton, and now it's gotten so bad I think I can see skeleton and I'm seeking help. I've...

Hey all, Can anyone help identify what this white stringy stuff is that I have growing on the base of my Zoa's? It took over 2 small polyps already. TIA

I recently got a small frag of a greenish toadstool leather (it was in the bargain bin and I don’t know the specifics on species, coloration, polyp length, if it’s even actually a toadstool, etc.) and after the first few days with it extending remarkably tiny and short polyps, it now has gone...

Hi All, over the past week or so a portion of my star coral has started to die off. I'm not sure what is causing it, or what to do. Nothing else in the tank is impacted. Here's a picture below -- any suggestion(s) on what it could be or what I should do? (It's the white part at the bottom...

I have a month with this green Goniopora and I bought it with a black spot. Is that just one dead part or a disease? I notice that it is getting bigger ..

I’ve had it for 4 months, I can see more of these “holes” were a polyp once was and browning on the edge. What’s wrong with it? Can someone give me some pointers? Recently tested my values and everything was in the norm. Would really appreciate some help as I’m quite new to the hobby

Hey Everyone, I'm new to reefing (and Reef2Reef!) and am currently at the stage of introducing corals to my tank (no fish yet, just some snails and conch). I added a Paly colony, a purple ribbon gorgonia, ricordia, montipora, and gsp back on September 12. Before introducing them I drip...

Hi everyone, I noticed this afternoon that my hammer is going through something messed up. Not sure what it happening. I sometimes target feed BRS reef chili, and also have been using Aminos from Brightwell. My tank is fallow to eliminate Ich. I'm testing my parameters now. My first that I...

Hi I am in need of some help figuring out what is growing on/happening to my frogspawn... it appears to be some sort of growth on the bottom left of the skeleton where the skeleton meets the frag plug. I have had the frag for around 4 months and it has been thriving in my tank. I do regular...
