fungal infection

Hey! I am a student in the Marine Science program at Central Campus in Des Moines, IA. In one of our aquariums, we have a Longhorn Cowfish (Lactoria cornuta). Over the past few days, a classmate and I have observed a rapid growth underneath the cowfish's mouth. The growth looks to be some type...

I have a Niger Trigger fish with a white spot. I’ve had him for 3 months now and he’s been in perfect health. The spot hasn’t multiplied or changed in size. It’s hard to tell in the photo but it looks fuzzy ish. No other fish has the spot and everyone has been eating. I don’t think it’s Ich, i’m...

I have two clownfish in a quarantine tank - they've been in there for around a week and a half and seem to be doing well. Both are eating and have selected places in the tank to host. I noticed today that one of them has grey patches over the white near its tail. The patches are on both sides...

My porcupine pufferfish has a cloudy patch on her right fin and seems to have a bit of a torn tail. I just noticed today after watching her eat. She was breathing a little heavy after feeding but she seems to do that sometimes. I have also only ever seen her puff up on a few occasions but saw...

Anyone have any idea what just sprung up on my blue damsel? I know it could be fungus, ick or lymphocystis, but I’m asking for advice from experiences. He seems happy and is actively hunting I just noticed it a couple of hrs ago. Look familiar?

Hello, I have a Melenarus wrasse that unfortunately broke it's jaw (or something) about 7/8 months ago. He can't close his mouth at all, and has basically lived just accepting he doesn't really have a job to do, but he has always been an active swimmer. He breathes hard. Constantly. I imagine...

Hi all! I am new to this hobby and know I’ve made mistakes from not so great advice. I currently have 60gal saltwater tank that is about a month old. Was told it would be cycled by adding fritz turbo start and all would be good. Long story short I’m having to do a fish in cycle because it didn’t...

I’m having a crisis and need some advice. I have a blood disorder and got extremely ill. My tank got the bare minimum from my husband(he just doesn’t know anything about fish keeping) and now that I’m home and able to get around some, my fish are all sick.....I’ve never had a sick fish before. I...

I think my Helfrich’s firefish could have a fungal infection. There is some discoloration on one side of the body, and there seems to be a swollen whitish area at the base of the tail. Additionally, the tail itself is losing some of its yellow color. The tail was bitten quite badly by another...

Woke up this morning to see my firefish with a red rash. Before this morning he already had some fin damage from a bully clownfish, which I have rehomed a week or so ago. However, this morning was particularly odd because not only was there a red flesh wound? that appeared, the fins seemed to...
