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’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.

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...

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.

One of my clownfish is showing white bumps around its mouth and I’m not sure what it is. I started noticing the white around its mouth yesterday but today there’s a pretty pronounced bump. Any idea what it is and how I should treat it if needed? Attached photos

Hey fellow reefers! I desperately need some help figuring out what is going on with my melanarus wrasse. A week ago I added him to my what was a coral and inverts only 29 gallon biocube. He is the only fish in the tank. He hid out for 2 days after I introduced him into the tank. After day 2 he...

Ok so I have a pretty in depth QT regiment following humble fish to a T using copper for 30 days the prazi for 14 days. It looks like a few of my fish have gotten white bumps but it looks like it's under the skin not on top like ick usually is. It's hard to see you have to be at the right angle...

I just bought a fire fish Sunday from my lfs. I also got a sand sifting sea star the same day. My tank is a mix of corals and fish... I also have a fire shrimp. Today is Wednesday and he did hide a lot in a cave since I got him, but when he came out he was swimming around fine and coming out and...

Hello, I have made a couple posts and comments about this, but figured I'd give it one last try to see if people can maybe help me pin point the issue my tang is having. Here's a breakdown. About 6 days ago I noticed my YT hiding in the shade and not eating normally. Usually very active...

I got home from a short trip yesterday and thought she was dead as I couldn't find her anywhere, until I found her in a strange cravice she is normally not in. I didn't think much of it, but since then she has constantly been hiding in little caves in my reef and didn't eat after I tried to feed...
