fish dying

Our tank has been easy and trouble-free for 5 years... two days ago we lost 2 damsels, a wrasse and a shrimp, next day another shrimp and now our coral looks like this during the day (strings coming off it) and shriveled tonight...not sure what is happening but scared for those left in the tank

Hi, One of my tangs has passed away. I have a Hyppo Tang and a Porcupine Puffer Fish that are barely hanging on. They are breathing heavy; the tang has started to develop marks on her face. She is on her side and trying to swim. Also, she is losing her color. We have transferred them out of...

Hi everyone, I’m newer to saltwater aquariums and I’m having trouble with my 20gal long aquarium. I started this aquarium about 3 months ago with dry rock and live sand. Made sure it was cycled 100% before adding anything else into it. I now have various corals, a peppermint shrimp, rock flower...

Hi everyone, so I have a 40 gallon IM cube that I set up the first week of May with live rock and running filter floss and media bag and carbon bag. I have a green chromis (full grown- sometimes a bully), 2 blacker mocha ice clowns, and then a zebra bar dart fish that I added 3 weeks ago. Zebra...

I just got home from the grocery store and my Mccosker's wrasse is lying down on the sand bed in the back corner. What is happening? He's been eating and active since I bought him from the LFS except for today. It looks like he's breathing heavily with sudden big breaths. All other fish are...

Hello, I am in dire need for some help, and any advice will be appreciated! I dosed carbon (as vodka) last night, but I put way too much. Wayyy too much. I have a 55 gallon with 11 gal sump and a 43 gallon with 10 gallon sump. In the morning I saw that the water was cloudy in both tanks. A...

I know this is a very large request, but I have a fish that is being bullied and is dying (there has also been a recent ich outbreak) and I have inverts so I can’t use ich meds in tank. I live in the Loxley Al area. If you have a spare tank of any size (even tiny is fine) that you’re not using...

My powder brown tang took an extra day to arrive and was very close to death. Water was freezing and some damsels that were also in the package were DOA. I got the temp up slowly for the tang and then began drip acclimating (water he was in had almost no alkalinity - my guess is dissolved CO2...

Would like people's thoughts on this. I have been keeping a mixed reef tank for years now, and have always fed my fish with mainly frozen foods! Last night I fed them with frozen krill, and to my surprise a white feather was introduced into my tank via the frozen krill. The very next day my...

Earlier this week I lost my coral beauty. Now my strawberry pseudo chromis is showing almost identical symptoms. I’m starting to think they have a type of disease. Can anybody help me, and what should I do to keep my other fish from this. Also my fish isn’t normally in a glass, I just put him in...

So, I thought I knew what I was doing - clearly I do not. Feeling a little overwhelmed and reaching out for help before I lose anything else. My ammonia is still high even after two water changes. Lost a six line wrasse and a valentini puffer yesterday - which I'm so bummed about. Fish were...

3 days ago i woke up to a cloudy tank and lethargic livestock and corals not opened up and mushroom splitting maybe from stress. Turns out my return pump in the back sump of my all in one tank had broke most prob the night before and i didn’t notice till 11am the next day so maybe 24h with no...

I have a 9 month old tank. Last week I turned off my return pump overnight due to a plumbing problem. I have a refugium with lots of macro growing in it. When I turned off the power for the return pump, it also turned off the light in the fuge. I fixed the plumbing the next day but noticed the...

Hello, I have a 100g mixed reef that has been established for about a year and a half. I have not added a new fish for about 5 months, and I believed all to be going very well. I woke up this morning and I found my Powder Brown Tang laying on the sand bed. I was in distress and looked at him for...
