dead fish

150 gallon new tank was set up and cycled with bottled ammonia for a month. After a month, added a Foxface and scopas tang. Several weeks later, added a powder blue tang, pair of clownfish, and a melanuras wrasse. During that time I also added a clean up crew and several small coral frags. The...

Hello All, I’ve had a Convict Tang for the past 10 days in quarantine with a Sunburst Anthias and two Bandai Cardinals. The Convict was a model citizen - very active, eating nori, and eating frozen mysis. I fed the quarantine tank this morning and no one acted unusual…until about a half an hour...

My blue sided fairy wrasse jumped out of the tank a few hours ago I guess and I JUST found him.. I have a hood on my tank, it's just raised about half an inch and somehow he managed to position himself perfectly through it. He was my daughters pink fish, she named plants. Mixed emotions but...

I'm fairly new to taking care of marine life and I recently got my tank stable, no more ammonia. But my fish keep dying. This is a new one that I encountered, I hope someone here has dealt with this or knows what to do since I don't know what to google or what it's called. Thank you!

I have a fairly new (fully cycled) 36g tank with two clowns, a Firefish and a clean up crew. I'm working up to more fish, but today I came home to the Firefish dead, floating with a wound in its stomach. For context, in the two weeks I've had it it has been very active, friendly enough with...

A few days ago I recently did a routine water change on my aquarium and when I plugged all of my equipment back in, everything seemed off. First, my Rainsford and Mandarin Dragonette were showing weird swimming patterns. The Rainsford normally liked to hang out in front of his hole but now he...

I just added 2 banggai cardinal, a YWG, a green mandarin goby, a blue hippo tang, and a flame angelfish from DR Reef's quarantine fish to my 200 gallon reefer xl Unfortunately the flame angel, one cardinal, and the YWG all died within 3 days. Water parameters are normal and the other fish are...

My fire goby started to get a red spot on the belly and after a few days it died. I’ve been searching and found something called uroema marinum, I hope it’s not that but I have no idea does anyone know? Thanks

My pretty baby seemed to die overnight! I am new to the hobby. I don’t have any pictures of it suffering, but last night it was swimming on the ground and I noticed the crest of its fins seemed ripped in one area. I wasn’t sure what to do so I figured I’d observe it for another day before taking...

This tang presents a little different than the others that died. They had a white fuzz on them. Velvet? I don't have great pics of those fish with it, they were hiding. First the Powder brown and another similar tang went down fast after showing some dark spots (larger than black ich, more like...

Ahhh… So I assume you have GHA (green hair algae) and you have been scouring the internet for success stories and ways people have beaten it. I was in your place 8 months ago but most methods I tried ended up failing so I’ll share how I defeated it. So here’s the beginning… I purchased a frag of...

I thought my tank was finally ready to add fish, but I woke up this morning to find 4 dead fish. I don't know what I did wrong. I added 2 saddleback clownfish, 2 damselfish, 2 banggai cardinalfish, 2 blue leg hermit crabs, and a turbo snail to my tank last night after double checking the water...

So, last night I went to bed and I turned off the light and I had 2 fish in my QT. This morning I woke up and there was only 1 fish?! After freaking out thinking somehow it got out and died… I stopped to look at the wave maker… and inside found my 3 inch foxface completely and utterly...

Hey guys so I recently purchased a wrasse as well as a new CUC I brought Scarlett hermit crabs, a cleaner shrimp, blue leg hermit crabs, and a couple snails. Now I have a emeral crab from my last clean up crew and the emerald, cleaner shrimp and blood fire shrimp all hang out on and in the...

So.... I had a clownfish die about a month ago now. That was my first time keeping a fish, ever. I am fairly new to the hobby, and I am wondering my next steps are regarding a couple things in my 10g tank. 1. I hadn't had the chance to test my water up until recently, and my nitrite and...

Hey fellow Reefers.. although im not a reefer yet, just an aspiring one, I have a freshwater aquarium which I am using to learn ALL (!!) I can about to graduate to a reef so I don't mess up. But now seems that im messing up! Now in the last weeks one by one my fish are dying off.. why?? Fluval...

Hello, I’m new to this, but I bought a gem tang Thursday along with a Midas blenny and a mandarin fish. I dripped the gem and mandarin together because they had just come in from shipment to my LFS. I dripped the blenny separate because he was already in the store for a while. Yesterday, I saw...

So I have a 10g half moon tank and it came with a lid, it was a used tank so I just made do and thought it was good enough. However today one of my clownfish decided to abandon ship and squeeze out through a small opening in the lid so I want to invest in a mesh top since I’ve lost 3 clowns now...

My boyfriend and I just bought a yellow tang 2 days ago(Sunday). We put it in our qt tank to watch for a couple weeks before moving to our main display. Perameters: 30g tank running for about 2 months now with previously housing some fish from our main display, temp 80F, salinity 1.025, ammonia...

I’ve had marine velvet in my tank for the last two weeks now and it has killed all of my fish so far. Does anyone know how to remove it from the tank and how long that will take?

I woke up this morning to find my bicolor angelfish upsidedown in the sand. The night before it was swimming, behaving, and eating normal, as it has been for the past 3 weeks. What’s strange is it’s mouth was lodged open and red. What could’ve happened? Maybe it ran through the power head, or...

Hey, so out of nowhere this morning I found my bicolor blenny dead. I had literally just seen him alive 5 minutes before I found him. I am just trying to figure out why he died? I am pretty much on top of everything regarding my tank. My two clowns are healthy and eating. The blenny has been...
