disease

Hello :) 6 weeks ago I set up my first ever reef tank. I have 2 banggai cardinals and two clowns (and some corals and other inverts). A week ago I added a six line wrasse which seemed very happy, no sign of disease or illness at all! However I woke up to find it had died two days ago :( The same...

I got home from a short trip yesterday and thought she was dead as I couldn't find her anywhere, until I found her in a strange cravice she is normally not in. I didn't think much of it, but since then she has constantly been hiding in little caves in my reef and didn't eat after I tried to feed...

Hi, My new PBT has swollen abdomen and he is not swimming like the first day added to tank. The first day, added to tank, he ate algea in my tank and also I fed him some clam with vitamin C and multivitamin. The next day he didnt eat any thing. also, he didnt eat algea. he completely looses...

Hi, new to reefing, I’ve been searching the internet for solutions but I can’t confidently diagnose this patch - it seems to be worsening (see photos). the clowns have only been in the tank 3 days although my parameters are all fine. I’ve not a clue - any ideas! Thanks!

I know it’s uncommon for eels to be affected by ich and velvet. But what about brookynella? I had a grouper who recently died from brook so removed all the fish except for a few eels. Now it looks like my jewel moray is having similar symptoms. Loss of appetite ( normally he’s a complete monster...

Hey everyone, just wanted to know whether anyone has experienced this before, and if its normal? I’m just concerned because my powder blue had similar black marks 2-3 weeks before dying of an unknown cause (which would eventually end up killing half my fish: tangs and angels). I ended up...

Hey everyone, just wanted to know whether anyone has experienced this before, and if its normal? I’m just concerned because my powder blue had similar marks 2-3 weeks before dying of an unknown cause. I’ve had the Moorish Idol for almost a week now, but his been eating well and has showed no...

So my girlfriend bought this pair of clownfish a week ago and today one of the two started showing signs of what looked like ich. It was weird because literally the day before hand he looked completely fine. Now he looks on the brink of death. He has spots on his body and fins. His eyes are...

Hey all, I’m getting desperate for some answers as my bristletooth tomini tangs health seems to be on a rapid decline. About 4 weeks ago, I noticed a white patch forming on the tang and it looked almost like the consistency of cotton. It started off small and after some research, it seemed to be...

was wondering if the spot circled on my annularis angel is just his pattern or something else, that was the best pic I could get all of my other fish are fine

Hi guys, I purchased this blonde naso tang and what I believe to be a Vlamingi tang. The naso tang has not eaten yet but the vlamingi is a voracious eater. Could you guys help me positively ID that fish, the guy I bought it from said it’s too early to tell what it is. Also can you guys help me...

Hey Everyone iv seen some other threads going from it’s corline algea to its dying that you might need to cut off the head, to its regular algae so i figured i would post my pictures. And make my own post for some personal help. So I bought these from Manhatten Aquairums, the guy was really nice...

Hey guys, tied googling this on my own, no luck, so here's my problem. I have a 40 gallon breeder with a devils hand in it. Lately I noticed a small black/dark spot at the base of one of its newest fingers. The spot was in such a position that I figured it was a trick of the aquarium lighting...

Hi, my three spot blenny suddenly stopped eating today and hiding away in its little cave. It was breathing hard so I thought of ammonia rise. Did 20% PWC. Later on, it came out and swam like frenzy, almost hitting itself to the substrate. In that instant, I thought he was a gonner. I decided...

Hi reefers, in an other thread @bboileau92 hinted me to the microbiome test from Aquabiomics which is able to detect pathogens in an aquarium. Now I wonder if there are other ways to know/detect if there are some "dormant" pathogens/parasites like ich, velvet, flukes etc. in a completely...

I was in a LFS the other day and saw they had a group of chromis. Not of great interest to me, but a couple had red blotches and my amateur guess was a possible uronema infection given the reported prevalence. It made me wonder, given the recommended "bleach everything and throw the rest away"...

Hi I recently bought this hippo tang.I’ve had it now for about a week now and since I’ve had it it has got some sort of disease I think and also hides at the back of the tank howveer I can’t diagnose it because I can’t find anything similar,I’ve attached some photos.If anyone has any ideas it...

Is this a healthy branching hammer? The dark spots on the bottom are newish and I’m noticing some darker top parts underneath the polyps... what should I do if anything? I did glue this to the rock when I bought it. Is that an issue?

Most of us believe that quarantining your fish is the best approach to avoid diseases wiping out our entire tank. I think most will agree on that. But ... does it also safe more fish lives overall?

SPS tissue degradation and loss, whether its slow (STN) or fast (RTN) or associated with a brown gelatinous mass (BJS) are probably one of the more or even most frequently discussed topics here. A particular emphasis is given on the „help“ requests describing the fast peeling and patchy loss of...

Hi everyone, So I bought this fish a week ago and today I noticed that their eyes got some cloudiness with it. I have a new tank and everything in it started from scratch. I am not sure if my tang had a little battle with my clownfish because one of my clownfish's tail had a little scratch...

Hello! I currently have a powder blue tang in a 20g Long QT. I bought him from petco and for the first 3 days he looked great, beautiful color and everything. I then noticed slight twitching and scratching against the pvc in the tank. With that being said i decided to start treatment with Ruby...

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...

Hi I am fairly new to marine tank as I only have kept freshwaters. I have one small orange clownfish and this fish developed white~opaque lesion on R) side of its body. I wasn't sure if it's just body colour change or some kind of infection? I kept this fish about ~1.5month. Noticed this lesion...

Fish came from a really nice store, they had been treated with cupramine in the store and held in a separate water system that I purchased them out of; any protocol for treatments? Should I treat for any parasite or any disease at all; or just watch the fish for a bit? Seems really healthy...
