sick fish

So I recently bought a Powder Brown tang and have him in a 20 gallon long quarantine tank along with a pintail fairy wrasse which seems to be fine. The powder brown recently developed what looks like darker blotches on both sides of the body, on one side more towards the tail and the other more...

HELP!!! My two clownfish are acting very different. The tank has been cycled for years and all nitrogen associated compounds are at low levels. We recently had moved a new clownfish into the tank and suspect it may be the cause of these two fish struggling. Any ideas or solutions?

My beloved Green Spotted Puffer has recently developed a swollen lower belly near its anus and been making stringy poop. He was doing fine for a few days and still eating, but recently stopped. He went a few days without eating and didn’t show signs of improvement. I’ve got him in a breeding box...

I’m new to saltwater I have a mixed reef tank. A few weeks ago my fish started getting these white spots wasn’t sure if it was marine ich, velvet or brooklynella. Every fish I had showed symptoms at night and was gone by the morning. Only survivor is my yellow watchman goby. Besides the fish...

Hi, I have a pair of clownfish that I introduced into my tank 3 days ago. The female is perfectly fine but I noticed the male isn’t eating, and he has a red gill on only one side of his body. He isn’t acting lethargic and looks okay otherwise. Can someone help me what might be wrong with him?

These lesions just showed up today, no new fish or corals added recently. He was eating fine yesterday. I've got a carpet nem, long tentacle and bubble tip, and am worried he got stung by one of them, but not sure. He looks "okay" but haven't gotten to feeding him yet. I just want to make...

Hello I treated this copperband with chloroquine phosphate for 14 days then transfered him to sterile tank. During observation I observed these "bumps" almost completely invisible when looking at his side but see them when he faces me I started a prazi treatment in the qt tank. Just need 100%...

I got this guy from Petco on Sunday. He was laying on the sand bed in their tanks so I knew he had some type of issue, but I had assumed it was an ammonia/high nitrate thing bc the whole saltwater section there had more algae than usual and red cyano all over. So, assuming it was a...

Hello, I recently added a Magnificent Foxface to my mixed reef tank. Its been a few days and I just noticed this spot on my foxface, I am worried its my first encounter with ich. Fish looked fine at the LFS, fish is eating well and swimming fine, no aggression issues besides some light chasing...

Ive had this dotty for a couple months and he was doing flawlessly, but over night has either hid completely ,(unlike him) sunk to the bottom, or is stuck at the top as he is currently. Never had any issues with the tank prior, and everyone else is ok. Water peramters (Nitrates, Nitrites, ph...

I got a yellow corris wrasse, 2.5 ish weeks ago. Went on vacation. And came back to it like this. Going to do a water change. But what else can I do ? It’s laying on the floor. Mouth is moving and it’s “breathing” but not well. Ph 7.8-8.0 Ammonia .25 Nitrite 0 Nitrate 0 LFS just had us start...

Hi all, I’ve had a 15G AIO tank for about 2 months now. I’ve slowly added creatures since then without any issues until this week. I had a lawnmower Gobbie die and now my clownfish is acting weird. gasping at the surface, breathing harder, etc. I’ve also noticed some white spots appearing. I’ll...

#fishmedic I just noticed this white spot on the top left side of my WTB tang, and I’m freaking out because I somewhat recently treated my whole tank with a 35 day hyposalinity treatment before I moved all my corals and inverts into here, but that’s no longer an option. It doesn’t look like ich...

IT'S BEEN A TOUGH FEW WEEKS Y'ALL! After losing a some of my beloved fish fam I almost wanted to just give up the whole hobby to be honest. But after getting my remaining fish back to healthy and vibrant I wanted to make this post as more a "lesson learned" post to hopefully help someone else...

Typically use this community for my Reef tank but figured i would ask on here too. One of my two 3-Spot Gourami is not doing well. Has not been swimming level (nose up) and stays near the bottom of the tank. Still has an appetite. Tail seems very frail in proportion to the rest of the body...

Whats wrong with my blue hippo tang? I left my house for 4 days during thanksgicing break and my healthy blue tang suddenly developed what looks like to be velvet or ich or soet type of bacterial infection. I need a second opinion so i know what to treat for. He doesnt just have the...

I stg, I know there is a learning curve, but I feel like I run into something new every day. I have a watchman goby, been in the tank about a month that I just noticed yesterday has slightly cloudy eyes. Per recommendation, I did a 5 minute freshwater dip to check for flukes & other...

Just put my YWG into my nano. He looked ok when I put him in. He did get dipped with hydroplex. He went in at night and lights stayed off for 12+ hours. Checked on him this AM and he looks like he got suckered punched! There is a small clown in there with him along with some tiny blue hermits...

Hello, I'm new here. I joined because I'm trying to save my blue tang. This fish is from a big name pet store. I pointed out the awful condition it was in and they were willing to give it to me for free to try to save it. I am new to saltwater fish, but I couldn't leave this fish there in that...

Hey was wondering why my Regal tangs now has a big white spot on him!! Let me know if anyone has any information and or solution don’t want my fish to die (Could be scratching from the rocks idk)

Hey all! I’ve had a porcupine puffer for about a year, with a handful of other tank mates. The past few months now he has stopped all eating as far as I can see, (always ate from tongs with no issues) he must be eating SOMETHING because he’s still alive and doesn’t look skinny, but he’s...

Any experience with tilting at bottom tank? Our little clown swims in spot a lot and keeps tilting over? He is only with us two full days now. The first day was a little rough, we did the fish in cycle with Fritz turbo 900 & stress guard, with a hour acclimation (last time in-cycle!). We did a...

So we pulled the trigger on a young mocha storm clown, he was very active in the bag.. we slowly acclimated (1hr) him to a 10g new quarantine tank. We dosed it was stress guard and Fritz turbo start and used imaginatrium boxed saltwater and a heater, plus hob filter. Probly put him in about...

Hi, all. I have a 30 gallon community fresh water tank. PH leves are fine, temp, etc... Two of my fish have developed white patches. It's not fuzzy looking, and they aren't small white dots. Does anyone have any idea what this may be? Currently, appetite and movement is fine. We had a couple...
