disease

Hello. My Box fish has white blotches on its fins and skin. It also has a cloudy eye. He is in quarantine and has been since I purchased him 3 months ago. He didn't start showing any disease until my Blond Naso Tang, also quarantined (but separated by an acrylic barrier). Got sick and...

So I have a Lepto and there’s a clear like substance on it. It can’t be blown off and doesn’t look like bleaching. Anyone seen anything like this before?

I’ve been treating my hippo tang with copper in a qt for almost three weeks and at first I was seeing results and now it’s worse. No water changes have been don’t. Should I increase the dosage of copper? (Look near face and on spine near tail)

This is my wife and I’s first foray into salwater. Our tank has cycled and got a pair of clowns. One of the little guys had been isolated from others since they were being aggressive and even nipped his caudal fin. The store associate ended up giving him to us for free as a pair to another...

My wife recently picked up this beautiful clown. Not sure what kind he is but his pattern is quite unique. He was sold as a “premium” clown from Petco at one of their magnet stores meaning they get all the good stuff. Their tanks are pretty immaculate and they even have saltwater specialists...

Hi all. I have had this clown exactly a year now. It's had this spot on its side since shortly after I got it but it's always been quite small. In the last few weeks it's gotten to be quite large and I'm not sure what it could be. It's never caused problems but lately he's been having trouble...

I had an ich outbreak in my DT about 26 days ago, and yanked all of my fish out of the tank, moved into multiple QT tanks. I have way more fish than tanks, and some would kill each other, so they are split over 7 QT tanks of different sizes. I consistently treated all of the tanks with Copper...

Does anyone know what this is up under his belly and how to cure it? He won't eat, either.

Hello everyone, I am currently facing a dilemma on what to do with my tank as treatment action. About a month or more ich or ich alike disease appeared on my tank and took out some of the fish. I bought a quarantine tank and placed the fish that seem to be sick on copper for a month aprox...

In all my years in the aquarium world, I've never struggled with fish disease like I am right now. I'm in unfamiliar territory right now. My display tank has what I believe is a bad case of Ich. It's been coming and going over weeks. I thought it was reducing but came back with a vengeance...

I woke up this morning to this. Not sure if I was just not seeing it yesterday but I usually look pretty close. But I know tang probably has black ich curable by prazi. But not sure what Fiji foxface has. I have no noticed a tad bit of twitching but not like overly dramatic. No scratching on the...

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...

And what are those yellow lines or fibers inside (maybe outside) of the body are? Isn't it disease?

Today I noticed something strange on my Foxface Rabbitfish. His behavior is normal and he’s acting fine. There are small-medium spots scattered on his side and they look brownish/beige. They are like nothing I’ve seen before as it doesn’t look like ick or anything else I can think of. It’s only...

Hi, Today, I noticed my male mandarin died. I found him on the bottom of the tank when I woke up. It is a big loose for me, as he was a part of mated pair, which has been spawning several times. On 21.11.2023 I noticed ich breakdown in my tank. I have tried to manage it, and I haven't had any...

Hi there. The other day I was at my lfs looking to purchase a pair of Wyoming white clowns for my new tank. I watched them in the store, checking to see if I saw any issues with the fish. They seemed fine to me. They were under blue light so it was harder to see. Once I got home and put them in...

Hi all, i’ve got two clown fish in my dt just live rock and live sand put in the clowns after cycling nother further so no clean up crew yet. One of the clowns started to show sign of a disease yesterday its brooklynella according to vetteguy53081 (thanks for helping!) Link to the clownfish’...

Help Just bought a beautiful blonde naso tang from a local reputable fish store and it’s on its side swimming in circles like it cannot maintain buoyancy. it also seems to be breathing heavier. We seriously just got this fish, and this fish had been quarantined in the store for quite some time...

Hello, everyone, I'm new here, someone help me, please. I Woke up this morning and found out there is something on my yellow Tang ‘s fin. Any idea what is it??? No new fish was added last couple months. It was added to my fish tank 4 month ago this year.

These two white dots appeared on his tail. I'm leaving for a trip Monday and I'm really worried if it could be ich. I don't want my tank to get wiped out. Currently don't have my qt set up because I wasn't expecting anything. I'm running UV. Dosed Prazi in the tank following normal procedures...

I don’t know what’s wrong. I lost 2 that’s the other day, and was told it was the newly added unsafe anemone. Now today, my yellow tile fish can’t get off the sand bed, and seems to have a piece of his take missing. This is NOT another fish doing this as I basically have nothing left in my tank...

Hi all, was just doing a coral feeding and noticed my clownfish has a slightly off-colored patch of scales above her pectoral fin. This is the only area of discoloration, and she is behaving like normal otherwise. My assumption is that she may have rubbed against a rock while chasing my...

I keep thinking about why it seems as though freshwater fish diseases seem less-commonly talked about compared to saltwater fish diseases and was wondering if anyone else had any insights/thoughts. My guesses on why this is were that: a. Freshwater fish might be more disease resilient as they...

Hi everyone, I have been raising 2 Horseshoe crabs for the last 5 years (1 is 3 yrs. old, 1 is 5 yrs. old) They eat well, have a big tank and are usually great but the 5 yr. old has developed Green Algal disease. His shell is turning green and splotchy, he's not eating much and moving slow. Has...

Oh boy.. I’m a longtime coral reefer. Don’t know what this but I know it isn’t good. My orchid dottyback started looking like absolute garbage today. Went from 0-100 in a days time. Eating, swimming, acting completely normal. As time has gone on I suspect it is already dead and my tank is...
