fin rot

A couple months back, I made a big mistake of putting unfiltered tap water from my bar sink into my reef tank because I was being lazy, and while nothing happened immediately it eventually messed everything up in my tank. As a result I got a massive bloom of green hair algae and dinoflagellates...

Hello! So looking for some advice. It seems like for months and months now we have been dealing with some kind of bacterial issues in our tank. As far as as we can tell it’s not affecting all fish, just some new ones that are added. The issue seems to be a mixture of stuff, from looking at...

Hi folks, I have a helfrichi firefish in 20G QT with cycled filter media. I noticed recently that there is a small split in his caudal fin. His other fins look to be in good shape. I tested for ammonia levels with a tropic Marin test kit and they don’t seem too high. I’d appreciate any opinions...

Gem Tang help please! Eating like a champ. Not afraid of any tank occupants/not getting bullied. My current theory is bacterial infection from transport or something, that got infected. Had for about a week. Can’t see in photo, but there is a small area that is whitish near the base of the area...

Hello everyone, I am "new" in the hobby (had a saltwater tank about 20 years ago that ended in disaster, and my frustration kept me away form the hobby for two decades), and I just got my first fishes, a pair of Perculas, one bigger and one smaller. Right off the bat, they started to nip at...

Hello, I have noticed about a month ago my six line was beat up. And I had believed it to either be fin rot, an attack, or badly damaged from darting around the rockscape. Is it possible the wrasse would almost completely take its dorsal fin off from scraping around the rocks? Or is it most...

Does everyone think this is ich? Got this Scott’s fairy two days ago and sitting in my QT. Eating fine on a combination of frozen blood worms, mysis with garlic and brine. I dosed copper a few hours ago.

I ordered this princess damsel off of saltwater fish and when it came yesterday, i thought i was a wound because it was just the top, and now after not even a full day of being in my display (I know, should’ve qt’d) the tail i white and looks like the fin is almost melting, and had white above...

Hey I’m curious about my niger trigger fin. Iv had him for 3 months and I noticed his bottom fin was damaged. He has been eating regularly and it seems to not bother him. I’m not sure if it’s fin rot or a mechanical damage. Any thoughts? Thank you!

Hello, I have a Timor erase that I’ve had for around two years now and he has been struggling for months now with something I would like help in identifying. He has a large lump on one side of him and what looks to be another lump starting out almost directly on the opposite side along with a...

Okay so I’ve just upgraded my mixed reef tank from a fluval nano to a 170 I quarantined the fish for 5 days before over loaded the power in my house 3 times!! So I moved the fish over. 5 days the fish had some suspicious looking marks on the fins. Today i the tail is completely shredded, red...

Hello! I received a Dejardini Tang the other day from someone who could no longer take care of it. However when I received it, it was in terrible shape. It looks like it has HLLE and I’m not sure if it has tail rot as it was previously housed with a porcupine puffer. I also can’t tell if there...

Hi guys! So picked up this pair on Saturday. Acclimated and popped them into my 180L tank, where they both hid in the rock work. Noticed this morning that one seems to have rather damaged fins, not sure if fin rot or is just from stress or perhaps bullying at the LFS? Is not eating but then has...

Hello all so I noticed about a week maybe 2 weeks back that my Royal Gramma’s tail was damaged, it hasn’t got progressively worse until maybe today it looked a bit more torn possibly, not sure but is this tail rot or another fish nipping him or? I only have a royal gramma, purple fire fish, 2...

Recently purchased a small High Hat, he's doing fine, eating and swimming around in the TTM bucket, but his tail is rotting real fast. I had dosed Kannaplex and Stress Guard into the bucket, today is the first day of dosing. Some of my friends told me that this kind of tail rot is very lethal...

Hi .... I've added (2) young clownfish into my tank. Everything was well for the 1st couple of days and then I noticed tears in one of the clown's tail fins and fading to white spots on the tail fin. Each day it looks like the white spots are getting more prominent and chucks of the tail are...

Just got 7 dispar anthias at least thats what i think they are the seller didn’t specify the species as they just called it rainbow fish or something. The seller said they were ‘old stock’ so they already ate pellets, i decided to grab them. They are being qted in a 70g now. They all are eating...

Hey guys I’m new to this forum I would really appreciate some help in identifying what is affecting my clown. I got her a week ago from my lfs. From the beginning I noticed that her tail was a little ragged, but I assumed it was from other fish nipping at the store. However since then it’s...

This is my Pajama Cardinal, Fred. I have him in a Fluval Evo with a mild-mannered ocellaris, a barnacle blenny, and a small peaceful CUC. No stinging corals, just those basic orange/green zoas, gsp, and a mushroom. No protein skimmer per se, but I do have a cheap little surface skimmer. Also, no...

I’m currently using API Super Cure Ick at half the recommended dose (I have 3 Mystery snails), and noticed my black molly (i also have 4 tetras, and 3 danio in 30 gal) is also showing signs of a possible secondary infection with fin rot. I only noticed these symptoms on my molly, most likely...

Can anyone tell me what is going on and how I can fix it
