dying coral

Hey coral friends. I just got this guy exactly one week ago and had a small section melting on the left side. Fast forward several days and today looks like this. How do I fix it? Please and thank you!!

I bought this sun coral on the 31st from a local petstore. The workers said they've been eating and healthy. They also said they've have been hardy and easy to handle. When I bought the coral it was closed and in a cave with what appeared to be very low flow. I originally placed it in the...

I made a HUGE mistake yesterday when I got my first online order of corals… in the excitement of receiving the shipment, I forgot to temp acclimate and went straight to dipping before putting into the tank… I realized my mistake immediately after but i had already dumped the water the frags...

I just bought an acan frag last weekend. It was from what appeared to be a healthy colony. The LFS cut two heads off for me to buy. I have no idea why it's dying. I have a 16-gallon full of healthy and growing coral. I initially had it on the sand bed in the middle, but just moved it onto this...

Hi all, new to the hobby here. tank is about 2 months old (after cycling), I've had this mushroom for about a month. It's usually big and puffy but today it's small and angry and has this odd dark spot on it. It looks as if the flesh is receding there or something. Did a 25% water change today...

hello coral friends, A few days ago maybe 5 tops my yellow tip torch coral started closing. I thought okay maybe its splitting so left it be. Wasn't until 2 days ago when I realized I have a problem. Pics and video show the torch 10 days ago, 2 days ago, today, healthy zoas shown taken today...

If you go to this (https://www.reef2reef.com/threads/candy-cane-coral-splitting-or-dying.962664/) you can see where the problem started, then I made it worse. My candy cane started off dying the Par was way to high. I moved it to a shaded area but for some reason one night I added calcium to my...

So recently (29th of Jan 2023) I managed to get my hands on a dragon soul torch head (which was splitting). The torch coral was very healthy in the reef tank of the original owner. From the second it was placed in my reef tank the torch coral never fully extended. First call of blame was...

I come from freshwater fishkeeping. And always wanted to give coral reef tanks a try. I read guides and watch videos on how to set up a reef tank. Every coral purchased with research done before hand for best results. I started with corals that are listed as easy to keep. Mainly soft corals. For...

Hello, I recently got 4 corals (GSP, Xenia, Zoa, and Micromussa) in the mail (shipped out yesterday). They were already warm, but we put the bag in the tank to match temps. Afterwards we dipped them then glued them into the tank. The Zoa opened up after 30 mins and the Micromussa looks fine...

My shipment from a recent live sale has been MIA about 24 hrs and UPS can't or won't provide an update. Seller is working hard to resolve, no issue with them, issue is with UPS....they are presently stuck in an area experiencing a heat wave. How long can they make it before turning to soup...

Hey there i got a trumpet coral today, before i bought it i tested my water and everything checked out but an hour after it being in my tank it shrunk a lot and white slime started coming out 8hrs later it looks like they are starting to erode or something as brown parts are coming on the fleshy...

Yesterday I recieved a shipment of corals that all looked amazing. This morning I got up to see my brand new Lobo coral looks to be dying. I don't know what's wrong or how to help it. Please help!

HI reefers. Hope all well. Off late i had been losing my torch coral heads one after another. Despite fragging the frag head could not survive the slow decay and finally Brown jelly was Visible just before its last breath. I searched various Forum and also read how Antibiotics can...

Help! I’m not sure if this lobo is dying or if this is normal. It still has decent color under blues but the inside/mouth looks worse. Is this normal? It’s been like this for two days now. All other coral are fine. A hammer got placed next to it without thinking and it got moved. If it’s stung...

Hi, I'm pretty new to keeping marine aquariums. I've kept freshwater planted tanks before and I thought I'd take a shot at saltwater. I have a 20g Waterbox Cube that's been cycling for a few weeks. I received a shipment from WWC of my first coral frags ever and was pretty excited. I got a...

Couple of weeks back I direct fed my Hammer some Reef Roids Nano. A few days later it expelled what looked like a brown jelly balloon. Some guys kindly replied to my question on here asking what it was and let me know the Hammer was pooping. However my hammer coral never seemed to recover after...

Hello, I have 3 candy cane corals in my tank. The flesh on one of them has steadily been receding over the past few weeks. Now most of the skeleton is exposed with very little flesh left, I realize that this one might be beyond saving. The other 2 candy cane corals have been doing fine until...

I haven't been able to figure out why my open brain coral is slowly dying, and then noticed this last night after the lights went out https://ibb.co/7VJ09PG My first thought was it kind of looked like an eye of a fish. This morning I pulled it out and on the bottom if it were these. I have...

Please ignore my algae/snail buffet. Tank is a Fluval 13.5 with stock LEDs. I got a freebie chalice in a recent online order, and it did not have a good time in the mail. The water was cloudy and smelled when I opened the bag. I did a dip with Seachem Reef Dip, then a gentle rinse with tank...

Hi everyone. I have posting here about this coral a lot, but it seems like it dead. It has some brown on it now as you can see in the picture. I know, however, that until there is nothing its still technically "alive". Should I first leave this in my tank? And second, should I do anything to try...

So I have been posting on here about my torch completely shrinking, but today a huge chunk of it fell off and it now looks like this. Is it dead? Should I take it out of the tank. If interested in parameters, look at my last post. Thanks in advance.

Hello all. I started my tank a few months ago. It is currently testing at Ammonia-0 Nitrite- 0 Nitrate-20 ppm Dkh- 10 pH- 8 Salinity 1.25 Temp- 78 I regularly test all of this and it has stayed pretty constant. My corals were doing great, and my torch and indo hammer both split heads showing...

Hello, I have a 100 gallon Innovative Marine EXT100, and I'm losing corals. For lighting, I'm using two AI 32HDs. I run a protein skimmer, refugium (which is not at all growing my chaeto), a Carbon/GFO reactor plumbed into the manifold, and a UV sterilizer. I started this tank in November 2020...

I have had a duncan coral in my tank since September now, and the past month or so especially it has been completely closed up. Can anyone help me figure out how to encourage it to open back up. It's one of the centerpieces in my tank so it would be awesome to have it back open again. Almost...
