I got 2 new clownfish on Monday and they have been preferctly fine until this morning when i found the black one lying down on the sand. I walked over to check on them and they got up and started swimming about. As the day has went on everytime i look over at the tank they are back there lying down and now the orange one is as well.
I keep my tank at 25 degrees but we are having a heat wave and unfortunately it was up to 30 degrees when i woke up, i have tried to cool it down by removing the lid and replacing it with mesh, a fan, turning up their wave machine and doing a water change which has brought it down to 28 degrees. Ammonia is 0 nitrites is 0 and nitrates are at 20.
Im unsure of it was the temp change or something else, i know they are funny fish but i am a worrier and dont feel this is normal for these 2 as they havent lay down before.
Its a 105l tank and they are the only 2 fish in it. I lost all my previous fish last year and these are the first fish i have added since.
There colour is good and i havent notcied any other changes to their bodies. They do still get up when i walk over but are lying down much quicker now. 20260626_010700.jpg 20260626_010650.jpg

How are you testing water? And disregard nitrites which are freshwater specific.
Can you provide a video with brighter white light, No Blues?

I use the salifert testing kits. I had kept the light off when i saw then lying down to try and reduce any stress and be on the safe side but since turning it on they are swimming about again. Have i been worrying over nothing?😅

Video does not play. You tube version best.

Welcome to Reef2Reef!

Before adding any medications, we should dig a bit deeper here;

Are the fish still eating well?
Are they breathing more rapidly than before?
Does the tank have aeration (not just circulation)?

I don't see any evidence of external disease in the videos - the fish have clear skin and are swimming with fins held erect. Sometimes, in the absence of an anemone, clownfish will sort of nestle in a depression in the sand.

I havent seen them eat the past few nights, definitely breathing very quick today. The tank has an internal filter and a wave machine at the surface of the tank. They are noticeably worse today.

That appears to be Amyloodinium/velvet, a gill protozoan disease. That's the only disease that can turn so badly so quickly.

It is difficult to treat - you could try a 100 ppm hydrogen peroxide dip to buy some time, but then you'll need to start a coppersafe treatment.

To do the dip, add 12.5 ml of 3% hydrogen peroxide in one gallon of tank water, or 3.3 ml in one liter. Add the fish for 30 minutes. Note; this fish is pretty far gone, so it may not survive the dip......

Thank you so much for your help. I think they have already passed, feel horrible i wasnt able to help them. My other fish seems fine but is there anything i can do as a preventative?

Sorry - in reading your post, I thought the clownfish were the only fish in the tank. What other fish are in there? Can you post a video of them so that I can look for symptoms?

Other than treating the other fish in advance of any symptom development, there isn't a preventative per-se.

One thing that might rule out velvet is the other fish remaining disease-free. True velvet typically infects all fish in a tank pretty quickly.....

Thank you so much for your help. It was just the 2 clown fish in the tank. I am worried that the other clown fish wont make it, and unfortunately living in ireland it can be hard to get most medications, and those we can get take a while to be delivered. Just keeping my fingers crossed for the little guy, they are still really young and i would feel horrible if they passed.

They could have thought it was night since you did that, I notice that sometimes mine sleep on the bottom

Edit... I didnt read everything before posting... sorry for your lose
