Baby Mandarin has ammonia burn!!!! PLEASE HELP!!

Yeah the fish is definietly eating well you can see shes nice and chubby in the pics

Yay. Yes, that’s good. It’s not a good problem so. If she’s starving she would just be picky. My back glass wall is completely filled with pods and they are pretty big. She’s still eating pods right now.
 
Right. Thank you so much. There really isn’t a lot of threads on mandarins so thank you so much .
Also make sure you get a properly sized tank, because in QT the pods dont usually have anywhere to hide, so make sure you stock the 8 gallon with pods constantly. YOu can even add a piece of live rock from the DT so the pods have a place to hide. Choose a rock with lots of little hidey-holes. Good luck !
 
We have lots of pods on the back wall. It’s definitely not a food problem. Please trust me, before the burn, she was pecking all over the place. She never stops pecking for long.
Awesome! Just remember that a tank with no predators means the pod population has a chance to increase at a slow rate. Now with a mandarin, the population will need to grow at a higher rate, under the same conditions (unless you add a refugium) now that your tank has a predator...keep us posted!

Thank you! Do I really need a QT though? I’m wondering because none of her tank mates scare her. They all protect her. From my cleaner shrimp who wants to clean her. And she seems to be eating and being happy.

Alright! Yeah, for now we are just adding pods constantly. About every three weeks, or when we see that there are only a bit of pods. Rught now my pod population is blasted with pods. We also got a bit of phytoplankton to feed the copepods. We added a bit yesterday.
 
Thank you all so much for the information and advice. I think I will let her stay in the tank with her tankmate fish protecting her and her pod population. I’ll keep you all updated. Thank you so much!!
 
It’s a royal gramma and a pair of clownfish. And fire shrimp and cleaner shrimp.
 
This is not ammonia burn, and if you have ammonia- Water quality is not good enough to support this fish.
this fish is affected by the Lymphocystis virus or bacterial effect. To remedy- water quality is utmost and you could use melafix safely to treat skin. Mandarins usually secrete a slime to protect their skin and when water quality deteriorates, it has to be corrected quickly as mandarins are not fighters when it comes to recovery from virus or disease.

Oh wow ur tank is stocked. I think you should be good to leave her in the tank. Just check a lot to make sure the burn isnt getting worse, and make sure shes constantly feeding, and maybe even call your LFS or someone/place that knows a lot about fish diseases and illnesses. Also I just got a new book with all fish diseases, bacteria and environmental issues. Is the colour fading from the fish or whats going one with the skin exactly?
 
With a total ammonia reading of 0.2 mg/L - there is not any chanse on earth that this is an ammonia problem (and no chanse up or downstair either). It correspond to between 0.01-0.03 mg/l of ammonia gas (NH3 - the toxic form of ammonia) and it will not burn anything

we had to search for the mandarin so we had to dig under the rocks
Probably it is a secondary bacterial infection in a mechanical damage cause by either your activities or that he/she had try to go down in the rock works.

Just leave him/her and observe - there is probably a chance that he/she will manage this by itself. As long as it eat, behave normally and do not show any darker misscoloration I would not stress up him/her with a transfer to a total new tank. I agree with others that a mandarin (and especially a small one) is not the best choice for a newly started tank - but thing is what they are and actions in panic will not save any fish.

Sincerely Lasse

Okay. Maybe it isn’t ammonia then. We’ll keep her under our eye. Thank you so much!
 
Hi! A mesh bag full of cheato worked really well for me. I have it floating in my DT (AIO tank) but you could definitely put it in the sump with basically any light as well. It’s a good breeding ground for the pods because the mandarin can’t get in it. Just give it a good shake every week or so and you’ll see all kinds of pods just swarming out. :) good luck with your mandarin and I hope it recovers!!!

Good idea! Thanks so much! I’ll definitely see if I can try that, I don’t have a sump, but I am looking at an 8 gallon tank that might be thrown out if no one wants it so maybe I’ll pick it up.
 
two months is going to be a real challenge in keeping your mandarin healthy. Personally, after finding the issue related to the lesion I would rethink the tank set up and look into either:
1) rehoming the mandarin to another established tank until yours is ready
2) add a refugium to your tank and seed with pods until an established population is set
mandarin eat constantly and need a constant supply of food all the time. I see so many people purchase these beautiful fish without the understanding of their heavy need for specific food.
I had to rehome my male madarin in my sump for several months when I added the female since both were decimating the display's pod population. as soon as the population in the display could support two mandarins then I put the male back and everything is now good.
+1 on this. Someone else on this forum equated them to hummingbirds. They need to feed constantly (not just once or twice a day like a lot of other fish). I also read these guys need a minimum of 30g to keep them successfully but maybe someone with experience can comment. I really want one of these guys but the 30g puts them out of my reach for now (plus the feeding). Some fish, even if small, have huge territories in the wild so they need that space. Obviously there are fish we would all like to keep but if we can't provide at least the minimum then we either don't get them or we rehome them. I have freshwater tanks and really wanted a pea puffer (which is literally the size of a pea) but they need a minimum of 30g because of the territory they keep in the wild. Looking at them I would never have thought this so I'm glad I researched them. Plus they also feed quite heavily. That put them out of my reach.

I’ve got it in the bottom of my 20 gallon, behind the rock work. I put a small piece of live rock in it so it sinks. Can’t even see it from the display side. :)

I’m aware. She’s still super tiny rught now. Once she gets bigger we might rehome her if she outgrows, but for now, I want to raise her. She seems really happy and we just have to pay attention to her actions. I really love her so, I always try and add copepods when there is t much left. She’s not decimating the pods like crazy and the pods on the back wall never run out. There’s still tons of pods. And I might try to teach her to eat frozen. We’ll see. Thanks so much!

Smart. Maybe I should do that. Yeah. I’ll discuss it. That’s a really good idea. Thanks!

Mandarins dont need big tanks, they are very small fish. Its the pods that one needs to worry about. If you can provide a good amount of pods for the mando you should be good to put one in a 20g or so, I wouldnt go lower.

The mando wont outgrow your tank XDD The biggest ive seen these guys get is like 3 inches, but the one I saw was about the size of a full grown clownfish (female)
