disease identification

Hello. I am new to the hobby. I have a blue-green chromis that has a white spot up near the dorsal fin. It showed up first this morning. I have had him for about a month. I don’t have a QT and fear I am about to see the consequences of that… he has been swimming around and eating fine. The tank...

My powder blue tang is 3 years old and has been healthy and happy up until a couple weeks ago. He started acting odd and I noticed he had what looked like small white strings coming off of his head. I freshwater dipped him and it seemed to have work for the time being. Fast forward a few more...

Hi, all. An unfortunate first post as my sharknose goby has passed away. I bought the fish, which seemed healthy in quarantine at my LFS, last week, only for it to quickly decline and die five days later. The fish was in my DT with a small CUC of snails and a Duncan coral (all quarantined). I...

My lavender tang was doing fine, then all of the sudden I found it swimming strangely and was very lethargic. He didn't eat, was upside down and hyperventilating. He was then placed in an isolation container in the same system for observation and feeding. He didn't respond to any type of food...

This shark arrived with black spots on its skin. Initially the shark seems fine. Two days later, the its skin begin to show discoloration and more black spots appeared. Attempted to dose the shark with 50 grams of sodium nifurstyrenate (100mg per 1g) in 3000 L tank. Also tried to feed the shark...

Hello! I’ve had a small yellow tang in my tank for about 6 months now. When I initially got him, he was bright yellow, but his fins have slowly turned brown. I thought it was stressed and he would recover on its own, but he still hasn’t recovered. Water parameters are perfect. I don’t have any...

Hey everyone I have a purple tang in qt rn and it has a single spot on its dorsal fin and has since I got it. Not gotten worse or better in any sense I’ve been watching the fish like a hawk. No medication has been dosed and the singular spot hasn’t changed. It also doesn’t really protrude the...

I just did a freshwater bath on my Midas blenny & leopard wrasse. Some white flukes came off but there were little brown round dots also. Almost the size of mini brown pellet food. Also some super tiny black - prob black ich for that one. Thoughts. Of course I already dumped the water so no pics.

Hello, So I had a small piece of live rock I wanted to add for my new angel from my other tank which likely has ich in it. I dipped this piece of rock in freshwater for about 20-30 minutes and then added to the tank. After about 20 minutes I removed from tank as realized perhaps the cysts...

Hi Guys, So got my first pyramid butterflyfish the other day and sadly he arrived in very bad condition. He wasn't swimming upright and had lots of strange markings on him. He also had some of the flesh of the mouth slightly rotting. I put him in my quarantine tank (which has very clean water...

Hello I really need some professional help with figuring out what is wrong with my Blue Faced Angel? I have a blue faced Angel and a dog face puffer and Hawkfish in quarantine and the Tank came down with Ich a week after purchasing the fish. I am on day 7 treatment at full dose of cupramine and...

Hi everyone, this is my first post on the forum I’m really worried about my clownfish. He’s a maroon clownfish(male) and I’ve had him for about 4 months. He’s been doing fine except about a month ago he developed a couple of grey blotches on his face and now he’s losing more color as you can see...

Hi all. I am having issues with my zoas. I noticed that they have started to not open up, some areas are disappearing and I am noticing a some are kinda turning black and disappearing. Can anyone hell. I have them in a relatively low flow and parameters seem good. Nitrates maybe a lil low since...

Is my Chromis dying? :( New reefer here. Quite upset by seeing ourChromis blackening / greying and possibly dying. It keeps swimming vertically in the same area and not sure what to do. It has lost a lot of colour as you can see from the first picture, the streak of blue you see is all that is...

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...

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?
