illness or injury?

Noticed this on my foxface during feeding, what is it ilmess or injury? What do I need to do? Should I treat it or will it heal on its own? Please help. Thanks.

Trying to see what's going on with my porcupine puffer. For some background, it was born with one eye so it's a bit of an outcast to begin with. It was happy and healthy for several months but then developed some kind of bacterial infection. I treated him for a couple of weeks and the infection...

Our lemon tang took a bad turn today out of nowhere. I don’t know if she was getting bullied or if she’s sick. I noticed she wasn’t really moving and was breathing hard - I grabbed her up to get a closer look and there’s some damage to her dorsal fin? Is there anything I can do, or is she on...

My yellow wrasse was being attacked by my powder blue tang and my royal gramma today. It wasn’t running away or trying to hide, so I put it in a quarantine box for safety. Didn’t even try to avoid the net. It was fine yesterday and all community member previously lived harmoniously. I can’t...

Hello, I got this royal gramma roughly 5 weeks ago. When I first put the fish in the tank, it was stressed and hid. I wasn't worried about that because that is kinda expected when getting a new fish. The fish got used to the tank in only a single day and seemed happy and healthy. However, when...

I’ll try to explain this as easily as I can Maybe about a month ago I noticed one of my Banggai hanging in one spot of the tank, upon closer observation I noticed a red lesion and his pectoral fins looked kinda chewed up (really hard to see with their clear fins but you can see it). At the...

Tank: 40 gallon with very small snowflake eel, 1 skunk shrimp, 1 peppermint shrimp, 1 urchin, 1 royal gramma, 1 yellow angelfish, handful of hermits and 2 conches, some snails Hi, I introduced my yellow angelfish to my 40 gallon I wanna say a week or two ago. Since I first introduced her I've...

Can’t quite understand what’s going on here. For the last 2 days this clown fish had been under the weather. Had him a year, no obvious changes to params recently. I did recently lose a new cardinal but I’m fairly sure was down to bullying as opposed to disease. Can anyone help? I treated with...

Look familiar? I think I need to set up a quarantine tank? Any experience/ recommendations on what to do? He is eating. A little stressed swimming pattern. He is in a predator tank but I don’t really ever see anyone bothering him Everyone else in the tank is healthy. This spiny box puffer is...

Hi! We recently got a guppy and his left fin is looking weird. It doesn’t look like ick but not sure if it’s a fungus/Illness or deformity. Tank is freshwater 20 gal, 79 degrees F, tap water(conditioned), ammonia levels 0, nitrate/nitrate 0 ppm. He can’t seem to move his left side fin and his...

Can anyone help identify what could have killed this blonde Naso tang? He came out of QT medicated with copper and looked beautiful. Took to a customer’s tank and he died one day later snd had these black marks all over him. Anyone know what it could be?
