disease identification

Hi all, just noticed this morning that my bristletooth tang has a white string coming out of his skin. Fish has been fine and is eating well and swimming around normally. I am worried that this could be some sort of parasite. Nothing new has been introduced into the tank in around one month...

Hey all! So I got this Copperband butterfly about a week ago, finally started eating again so that is exciting! However, about three days in he developed this kind of white fuzz. One on his top fin, a bit on his side fins and his back fin as well. It appears to be growing a little throughout...

I need help diagnosing what disease my idol has. Ive never seen this disease before but im thinking its either a virus or parasite. It started as this for a few days : And has progressed to this overnight two days ago : Visually it reminds me of stress spots on a powder brown tang but more...

Sorry for the long explanation but hope it helps. I did not have my treatment quarantine ready to go when I got this small Hippo Tang (#1) so I put him in an “observation only” quarantine for two weeks. He never showed signs of disease so I put him into my 310g display tank and he was doing...

This whitetail bristletooth tang I got yesterday has some spots/light marks on its body. It came from a frag tank at the LFS that had some egg crate in it that it could swim under. Is this Ich? It doesn't quite look like it to me. Is it just marks from rubbing against things? Any identification...

Hello, I work at a pet store and the lionfish that the aquatic section had died in a very strange way. I would like to know the reason for the death so I can help make sure it never happens again It developed a weird lump then died

My Mimic Tang has been in quarantine with no other fish for 20 days without any treatments. Today my Mimic Tang appears to have an extended mouth or an infection. Still chases after food and remains active. Any thoughts?

Hi fellow reefers, Question: (answers from experienced reef tank owners preferred) Based off of the provided information and images in this post, does this Melanurus Wrasse appear to be injured or sick? If sick, with what? Background: About 3.5 weeks ago I purchased this Melanurus Wrasse from...

I got these bonded yellow tilefish about a day ago, and at first I thought one of them was just a little chunky. but they appear to be constantly fighting to sink. often resulting in them sticking themselves under something. both of them eat very well to my surprise. I started metro in the...

I’ve had my green chromis a couple of days, all been fine. But today I noticed all of them have these small white spots on their fins and tails… I'm not to sure what this is? have attached pictures.

My fire goby started to get a red spot on the belly and after a few days it died. I’ve been searching and found something called uroema marinum, I hope it’s not that but I have no idea does anyone know? Thanks

Been in qt for less than a week, just noticed this on the female. Others look fine, if it’s sick please tell me what to do I have no clue about dosing any treatments just trying to do this the right way. Also I haven’t noticed much aggression.

Hey guys, i noticed a white line on my clownfish tail. Im no expert but i dont think its ick. But let me know what you guys think

Hi all I’ve had this blue tang for around two weeks when I brought him he had no signs of any illness. He is currently in a quarantine tank and isn’t medicated. He has had these scars appear on his sides recently. He does like to sit near rocks so I assume he is scraping himself against the...

Hey guys.. I made a similar post about a month ago. In my reef tank invertebrates live fine, my blood shrimp keeps eating like a pig.. I do also have a ricordea florida an acan and a styllophora which all are doing great. During the past 2 months any new fish I added has been dead within a few...

Hey you guys. Got this brand new Anthias fish and put it in QT. The following day I notice it has this white patch. Does it look like ICH? Or lympho? Thanks you guys.

Hey y'all! I suspect my royal gramma has lympho, as it has two white, raised nodules on its head that resemble cotton. In other words, it has a fluffy look to it. The royal gramma (as well as the firefish that it shares its tank with) were bought from an LFS that quarantines its fish with...

Seeing a few scattered white dots on my Foxface and also the Naso. Tank is 120 mixed and the parameters are all in range. I feed a mix of Cobalt flakes with probiotics, frozen brine, and nouri. Just noticed these. Also have the filtration going through a UV.

Over the last few days, I've noticed these strange growths on the side of my Midas Blenny, they seem like sharp hair-like crystals. No other fish show any signs of similar growths. Her movements around the tank and eating habits don't seem to be affected in any way as of yet and was hoping...

I recently was given two frostbite clown fish and i noticed in day 1 that she had white spots of scales on the side. And last night i noticed her face is turning white. Does anyone know what is the cause of this and how i can fix this?

Hi everyone. This is my first post but have been lurking for a few months now. My tank is 5 months old and It’s my first ever aquarium. I purchased my chromis about 3 weeks ago and it’s been active and healthy. It currently is exhibiting two symptoms. 4 days ago, these grey/dark spots appeared...

this coral has been very irritated and is turning white and dying in one area. The polyps have been closed mainly. Has anyone seen anything like this? All other corals and fish are fine!

Hello, I woke up this morning and noticed my blue spotted jawfish not in his normal area in the tank. I just checked and now his markings dont look right. Tank has been setup over a year and all other inhabitants are active and healthy. I've had the jawfish for about a year. Any idea how to save...
