Black spots on my clown fish

[xiaoyuliang]

Both of my clownfish showed black spots on their body. A large chunk around ground fin. They also stopped eating and kind of breath quick, hiding in the shade. They were super active and eat like pig before please help me the bad thing is a don’t have a qt tank now. Hope it’s curable.

Looks like hyperpigmentation.

They can get it from hosting a torch coral or duncan.
Rubbing against a coral causing irritation.

Keep an eye but not life threatening.
Remove the coral if you see this and make sure they have plenty good food to eat.

Are you sure the spots are brand new and spreading quickly? Mine have developed them slowly over time, pretty common and benign, believe the theory is they can get stung by things they try to host.

How long have you had them? Anything change recently in the tank? (Very large water change, etc)

Thanks! I don't know if there is a coral issue. I also have dino at the same time and the corals don't look great honestly. And it's not eating right now should I keep putting food in there?

Looks like sting marks and likely anemone, euphyllia such as hammer coral known as Hyper-Melanization and will go away on its own. Maintain good water quality and diet.

Dont put the food in more than whats being eaten.
What kind of food?

Actually, I did two 30 % water changes to fight dino. Could it also be a stress outcome?

I have frozen brine and frozen Mysis as well as nori sheet. They didn't eat any of those so far.

Actually I'm not sure if they just showed up, I started to worry since they stopped eating and saw those spots. I did saw them swimming around a torch recently.

This is the correct term.

Its been a while.

Thanks vetteguy. Always a pleasure

Its the torch coral/ euphyllia stinging as they try to host forsure.

It could be, if new water isn’t close to tank water params (mainly salinity much higher or large temp difference) it can cause stress or shock. If they start eating again soon that was probably it. When I’ve had fish stop eating I try to get them to start up again with frozens.

I have been changing out 2.5 gallons out of 90 total system volume every few days as I’m doing a tank transfer method QT for new fish, you can see exactly when I did those small water changes from my reef-pi output. For the 15%+ changes you need to make sure new water is in the ballpark of the tank temp

Not enough. Do this:
Prepare by starting with a water change and blow this stuff loose with a turkey baster and siphon up loose particles.
Turn lights off (at least white and run blue at 10-15% IF you have light dependant corals) for 5 days and at night dose 1ml of 3% hydrogen peroxide per 10 gallons for all 5 nights. If you dont have light dependent coral- turn all lights off.
During the day dose 1ml of liquid bacteria (such as bacter 7 or XLM) per 10 gallons.
Clean filters daily and DO NOT FEED CORAL FOODS OR ADD NOPOX as it is food for dinos.
Day 5,, you can start with blue lights - ramping up and work your white lights up slowly

The salinity is perfectly matched but the temperature is 2 degrees higher. Maybe that's the reason. I guess I'll wait one more night

Yes, that can cause this variation

Can you post a short video?
How long have you had them?
The black spots are not related to them breathing fast and not eating….those are serious symptoms that need to be dealt with right away.

Are these the only two tank inhabitants? if so, and if they've been there for a while with no significant stressful event (like moving to a new tank rather than a 30% water change that doesn't match the tank parameters) I'd say it is temporary. I've had my clowns for several months now, and my 20 gal has never had a problem, but we did introduce some clowns to the 75 gallon and they all died within two days from Brook. The two specialty clowns that were in there survived, showed now symptoms, and continue to do fine as we've added other inhabitants. They might have Brook, but if so I haven't seen it in them yet.

I'd think your black spots are related to their environment rather a disease. Remove any stinging corals and dose something that might replace the slime coat on their body, perhaps Stress Coat for Saltwater, along with some low does of bacteria to the tank. You also might want to slow down your wavemakers and put an air stone down in the tank temporarily if they are breathing heavily. If they are having a hard time swimming, turn the flow down almost to nothing so they are not fighting currents.

I just had some better videos under white light to show their rapid breath and black spot. Do I need a qt tank now? If so, which medication should I use now.

Also btw could anyone help me ID those algea?

thanks y’all so much

Hi all both of my two clowns dead in the last two days I don’t think sting could kill my fish so quick. I’m sure there should be a parasite. Now I’m in the fishless phase for my tank. How long should I wait to make sure I kill all the parasite . And should I do some after change the water is kind of cloudy now. Do I dose any addictive to help clean the water? Seems like all my invertebrates are fine( peppermint shrimp, hermit crab, snail) but I’ll double check tonight.
