dying

I’ve had him for about 6 weeks, full extending and eating good. But since last week he has remained closed and refuses to open, any tips? And here’s what he looked like before

My frogspawn has been doing well for the 15 or so months I've had it. Two days ago, it was retracted. Yesterday, it started to dissolve. Today, it's worse. It could be fighting with the Hydnophora that is above and behind it, but the problem started in the head furthest from the Hydnophora. I...

So I'm at a loss. All the fish in my tank died except for one scooter blenny I got when I first set up the tank. Tank was running smooth for the first 6 - 7 months. I had no issues and it housed a pair of clowns, midas blenny, goby and the last man standing the scooter blenny. The goby died...

Hi all, My toadstool leather has gone from open and growing to the second image below. It’s been this way for around 7days. Is this on its way out??? It’s been bigger than the open pic but not images of it. I moved it to sandbed a while back and it’s had been open and growing in the spot it is...

So my fish tank cracked when I was moving it, I used rags to collect some water and through my corals and fish and rock in a bucket, I ran to the store and bought premade saltwater, now the next day I tested my tank and it’s at ammonia is through the roof!!! Not sure what I can dose to lower...

Hi all, I have been working at a lfs over the last year and some change and I’ve seen a decline in their Sps coral flats. I’ve kept heavy mixed reefs and had success with high end sps before but now I will be taking over the responsibility of these huge systems which I’ve only had under 50...

Hey guys, Recently i lost 3 sps that died slowly as an infection or something like that. Today i was cutting some dead branches and noticed that almost all of them had this guy in it.. Does anyone know what this might be? Looks like a white venom to me, haha.

I've had this hammer since mid September, and its never opened up more than It has in its first week. It looks nowhere like it did at the swap when I bought it (it was bicolor, blue and green) The first photo is day one in the tank, and the second is today. The last month or two has been...

Hello folks! Hope everyone has had a great weekend! I'm relatively new to the hobby and got my first Red Sea Reefer 250 a couple of months ago.. Last week I added my first corals and all seem to be doing well with the exception of my Candy Cane.. The first 2-3 days it looked happy but now it...

My tank is 1.5 years old . I can’t keep ANY torch coral alive! My parameters are rock stable. It’s so frustrating! I can keep hammer corals just fine and even some Acros sticks. Anyone have an idea on the cause? Also this type of frogspawn I can’t keep alive Dosing Kalkwasser & Brightwell Mag...

Hi all. My anemones has been looking worse and worse over the course of the past month or so. Started off looking awesome which I have attached to the pics. Since then I’ve had one move all around the tank and the other just not fully opened. Parameters are below. Would appreciate any insight...

My Macroalgae seems like its dying, new growth has turn whitish. Has it gone sexual or something else like lack of nutrients? This tank is a cycled tank without corals yet. nitrates are around 20-40ppm and phosphates are around 0.6-1 ppm. Light is strong freshwater plant light. If so what...

Hi Everyone I got 14 rfa in my 150 g tank recently two of my beauty started to loose tentacles. It is obviously rotting and falling a part. Does anyone ever had something like theese? Please see below pics and tank parameters First I tought they get too salinity 1025 Temperature 24.5C Ca 415 kH...

Help! We have a huge setosa that is a real showpiece in our tank. Last night, I noticed a concerningly large section is dying off, and it's happening quickly. (Honestly, it either happened like within a day, or I'm somehow just completely blind considering I sit and just watch our tank every...

Okay i have a 20g tank divided in the centre for my clownfish breeding project. New fish seem to be dying for no reason but there definitely is a reason which i dont know yet. Swimming happily at 6pm then dead at 9pm. But then theres others in there which are fine. Same tank same water. The tank...

I used to be pretty active on here, years ago. Excited to see if some of the OG's are still around. Firstly, thank you for your help in figuring this out! My Tank is a 29 Gal JBJ Cube with Eshopps Nano Cube Refugium Sump Roughly 33-35 gallons overall. Parameters are pretty stable (I will...

hi everyone, this is kind if urgent. So i recently got a anemone and did everything correct into adding it in. I made sure the salinity was ok(1.025), ammonia was 0, nitrite was also 0 and some nitrate. I recently got into this hobby and I read that if you wanted to add corals you would have to...

Hi everyone, I have a reefer 170 for about 10 months now (dry rocks started cycling 2 months earlier), but one of my problems is trouble with my first Montipora Digitata's. A while ago, I decided to test some easy SPS, but things have been going poorly. I know my tank is quite new and...

Every fish in my 60 gallon (20g sump) has died besides my melanarus wrasse. I had a pair of pink skunk clowns, mandarin goby, lemon peel angel, coral beauty, powder tang, clown tang (both tangs were under 4” and would have been transferred to a 200g that is being converted to salt now)...

Over the last two weeks I’ve had two fish go on me, the first was my scopas tang. Looked so weak he was laying down all over the tank so I pulled him and put him in QT, however he eventually passed. Now, about a week or so later I find my blonde naso tang looking a bit weak and swimming a bit...

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'll get the tank stats out of the way first. 20 Gallon Cube AIO with AI Prime 16HD running on David Saxby preset. It's about 6 months old (not including the cycle), and for the first few months everything was going well, corals were completely open and growing, and now pretty much all of my...

Hey guys over the last three weeks my encrusting and happy Bill Murray SPS has been suffering from what I can only guess is STN. I’ve had RTN years ago, but this is completely different. It started with the backside becoming white but leaving the tips still colored, if that makes sense. Over...
