disease id

I visited my dad and saw that his blue tang in his fish tank looked sick. It looked to me like it could be marine velvet but there was also just a general deceleration of the fish and didn’t know if there was another issue with it. I advised him to take it out of the tank to keep the other fish...

My tank is only about 2 months old. Added a Naso about a week and a half ago. He never really seemed right. He’s eating still but been very picky. He also hides a lot, but the last 2 day has come to the glass more. He’s had white stress spots on him ever since I got him, figured they’d go away...

Have a pair of B/W clownfish in QT after noticing some discolouration on the female and head shaking behaviour from the male. I suspected flukes, brook also crossed my mind, however the discolouration was very mild and did not appear to be similar to the mucous seen in brook. I treated with a...

I observed several discolored patches on one of my clowns with white spots in the center of each patch. The white spots appear raised. It doesn’t look like ich so I am trying to determine what this is. This is my male and he does get roughed up by the female occasionally (the reason for his...

Hi Can anyone ID the disease on my neon goby that's appeared all of a sudden? Is it white spot? None of my other fish are showing any symptoms

I need help, and I'm at my wits end. Relatively new to the hobby. I have a 120g mixed reef tank wand have been keeping fish since the end of December. At one point inverts snails urchins. I had 4 clowns a tomini, coral beauty, Diamond goby, yellow watchmen, 2 Firefish, and royal gramma. All were...

Noticed my fox face is breathing heavy and his gills are a bit bigger than usual but is color is fine. I saw him eating earlier off of the nori but haven’t seen him eat since even after adding food. He does have a spot of ick on him (he’s survived it before and it’s in the tank) I have a qt tank...

Hi, Reef2Reef! Long time reader and hobbyist. I have a mature clown that is having some issues. LFS is stumped and so am I. I'll start with tank params. Salinity 1.023 Ammonia 0 Nitrite 0 Nitrate 0-5 PH 8.2 40 gal aquatop has been up and running for about 8 months. Everything else in tank...

Noticed my damsel wasn’t swimming around. Found it like this (see picture). Still swims, sometimes upside down. Very lethargic/easy to catch. It is in a “newbie mistake” overcrowded tank, but it’s generally peaceful. I’ve qt’d the damsel and have dosed my tank with Reef Rally Pro. I’m...

Have had this coral in my tank for a few months ( not sure the name it was sold to me as a mushroom coral) and it seemed really happy grown heaps almost always opens up during the day (including today) however just noticed when the lights turned off that it had this going on. Any help would be...

Can someone help me ID this disease? I noticed a spot on this guys fin a few weeks ago but didn’t think it was anything until I saw this today.

Hi, Can someone please help identify or explain what this white string growing from my hammer coral? It’s attaching to my rock. It’s about 1-2 inches long. Also, it has some small white spots(2-3) on its body. Tank is about 3 months old. ALK- 8 Cal-400 Nitrate- 8 Phosphate - 0.00 PH-8.3 Thanks!

Evening all, I have recently purchased a purple firefish for my nano tank. The fish comes from a copper treated tank from a supplier here in the UK who did the QT on my behalf. Recently i have noticed that the fish has developed 2 large white lumps on its side and top, shown in the attached...

Hi all. I have had this clown exactly a year now. It's had this spot on its side since shortly after I got it but it's always been quite small. In the last few weeks it's gotten to be quite large and I'm not sure what it could be. It's never caused problems but lately he's been having trouble...

I had an ich outbreak in my DT about 26 days ago, and yanked all of my fish out of the tank, moved into multiple QT tanks. I have way more fish than tanks, and some would kill each other, so they are split over 7 QT tanks of different sizes. I consistently treated all of the tanks with Copper...

I have a Duncan coral, candy cane coral, mushrooms, and zoanthids. My Duncan pictured in the bottom right was closed up today, so that just makes me wonder if it is the Duncan by trying to host since he always has slept near it even before I put the Duncan in place. I also put a six line wrasse...

Found one of my ocellaris clowns lethargic in the bottom corner of the tank tonight. His color is paler than normal and his breathing is labored. I’m not 100% sure my clowns have paired yet, but they seem to get along fine and he is a little smaller than the other. I was able to remove the fish...

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...

Hello All, please take a look at the two pics of just one of my Lyretail Anthias harem. The harem was added to the DT about 5 days ago and this is the only one that is displaying 2 wide light colored "bars" across the side of the fish. These bars are only on one side. Luckily the fish is eating...

This morning when I checked my tank, there were no dots on this clown, but when I was checking this afternoon he was absolutely covered in them. I’ve moved him into a qt. Wondering if it’s ick or brook? I’m fairly new this tank is a year old and the clown I’ve had for maybe 8-9 months. I really...

Hi! Like the flair says, a little bit of an emergency. Within the last 24 hrs, one of my clowns went from perfectly fine to this either growth or wound on her stomach. (Or best case scenario eggs? I know that’s prob not the case… However she is the female of the two). Other tank mates that I...

Hello and Happy Holidays! My Powder Brown Tang has had these white spots for three weeks now. I first thought it was Ich and have since treated the tank with copper power (two weeks in with therapeutic level) testing daily and maintaining between 2.0 PPM - 2.2 PPM. Any ideas what else this...

hey guys so I’ve been fighting a parasite which I thought was ich for the last week or two. I was treating with polyp medic lab, running a uv sterilizer, feeding nutrient rich foods and I thought everything seemed to be going ok. At first nothing got crazy better, but it didn’t get worse. So I...

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...

Hi everyone, I’m new to marine and have recently set us my first saltwater aquarium. I have introduced 2 fire shrimp and earlier this week (Monday) a royal gramma. All water parameters seem to be ok with no ammonia, nitrate or nitrite present and the KH,Mg & Po in check. I noticed my gramma...
