disease

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...

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...

Hi all, I got this clownfish from PetCo (5 days ago). My other clownfish (not from PetCo) seems fine. The tank has 3 ppm Nitrate, 0 nitrite, 0 ammonia. Salinity is 1.025 sg. pH is 7.9. This was the clownfish yesterday This is it today The fish eats and swims normally. I gave it a...

I have a pair of clowns that have been hiding a lot more recently. I have double checked triple checked for signs of disease but see nothing. They have a good appetite and come out when I approach the tank. One hides in the back and another between the rock structure. I noticed that maybe both...

Please help today I’ve noticed white patches on my black clownfish and I can’t seem to find what it is. I’ve seen a lot of ich pictures and they seem really small but these patches seem bigger. This clownfish always got bullied by the big orange clown and couple smaller orange clowns. Please let...

So I just noticed this today on my LPS coral and I’m stressing, looks like rotting, let me know please !

Hello, I have two clownfish and both of them have started to act weird, one more than the other. One clownfish first started acting lethargic and not eating 2-3 days ago, it just hovers at the bottom corner of my tank. There was some stringy white poop coming out of it when I checked on it...

Look familiar? I think I need to set up a quarantine tank? Any experience/ recommendations on what to do? He is eating. A little stressed swimming pattern. He is in a predator tank but I don’t really ever see anyone bothering him Everyone else in the tank is healthy. This spiny box puffer is...

I added two clowns to my third marine tank. They are the first guys in. He had this spot come up in his eye and it seems to be getting bigger. Any idea what it could be? I don’t think uronemia which I had before on some fish. The white horizontal line is gone but the spot is causing his eye to...
