Residents: All of the zebrasomas we've had for several years now. Newest additions are convict (which is why he's so skinny), orange shoulder, clown, and naso- within the last couple months or so. Everyone appears to be fine. Acclimation and introduction could not have been more perfect. No gasping, no trouble swimming, and all are eating like neglected little pigs. All of them follow me around the tank, because I'm the food lady.

We just finished up the 10 day treatment for ick yesterday. And just to be on the safe side, Ruby reef rally pro treatment- the yellow tang was looking a little funny, but he's all cleared up now. (Our very "high spirited" purple tang WAS NOT a fan of being caught in the 200g and relocated into the larger 400g tank. Which is what triggered us to start the ick dosing process.)

I, personally, haven't seen a growth quite like this before on the naso. We decided to add a cleaner wrasse, and at first it looked like he was really doing his job, but today the naso looks a little more questionable. I'm hoping it's just little tumors or skin tags, like "fish moles", but my biggest concern is that it's something possibly contagious. It's on both sides of the dorsal fin and there's a circular spot on the forehead right where the dorsal starts. As of right now, no other tangs have any similar symptoms.

Thoughts?

The blonde naso looks like it has Lymphocystis, a self-limiting viral disease that will go away in 4 to 6 weeks, it is virtually never fatal.

Please note - that doesn't mean that they don't also have some other disease though, it's just that the visible lesions are harmless.

Three of the tangs look pretty thin. Folks often feed nori to tangs as the primary food, but that is low in protein and fat. To really bulk these tangs up, you need to also feed them things like mysids and pellets, multiple small feeding per day, until they get their body mass back up to normal.

Appears to be lymphocystis which is a condition and not disease. Often its associated with water quality issue as simple as elevated ammonia or nitrate and can be that of water from LFS and not yours. Assure to provide Good water quality monitored by a reliable test kit and feed nutritious food with fats such as LRS nano frenzy and mysis shrimp.
Agree as mentioned by Jay is your fish being thin. Unfortunately for about 18 months now- this has been a trend. An influx of these fish are coming from Sri Lanka and it is suspected that a method of capture is contributing to this trend in which the fish appears healthy the first few days and then weakens quickly with loss of appetite and strength and as you found laying on its side, thin body and breathing heavy until death. It may be due to cyanide capture but unconfirmed. If yours is eating . . . . add some other foods for all your tangs such as :

LRS herbivore diet
Formula 2 flake and frozen
TDO Pellets
small plankton
Hikari Marine cuisine
Ocean nutrition veggie diet
spirulina brine shrimp
mysis shrimp
Prime reef
Nori seaweed basted with garlic extract

Add selcon vitamins to foods occasionally

Thank you both for the lymphocystis diagnosis. I'll be sure to keep an eye on that.

I, personally, am not overly concerned with the "thinness"... yet. Mainly because I haven't seen gasping, lethargy, obvious distress, excessive hiding or timidity, overly aggressive, refusal to eat, etc. (This is my husband's tank- and this is his hobby, so I'm seriously just guessing at how long some of these newbies have actually been here. I really don't know. He sneaks fish in this house like a ninja. But the newer fish are significantly smaller in size than the veteran residents.)

He's got a setup to where he can watch all the levels in tank from work, turn things off and on from work, and even added a home security camera in my living room so he can watch the tank from work... it's ridiculous. But his schedule is 2 weeks out, 2 weeks home.

These boogers have more food in my freezer than I have people food right now. Once it starts encroaching into my fridge- I'm going to a scratch and dent store to buy the fish their own fridge and freezer (eyeroll). I feed 3 times a day, and to be frank- sometimes I feel like I'm over feeding, but there's never any extra lying around because of the gobies and inverts. He's been podding like crazy over the last few months too, and has decided to start stocking up on frozen coral food- which all the fish seem to love as well. We have mysis, brine- frozen and hatched, frozen eggs, carnivore food, herbivore food, nori, a plethora of pellets, left over krill from when he had a snowflake, he's even gone to the local grocery store before to buy fresh raw gulf shrimp. (I wish me and the kids ate that good!!)

I think the smaller tangs just need to figure it out themselves, get in there, and get their fill. Which, admittedly, is difficult when the bigger fish are bullies at feeding time, but I have faith. Again, thank you both.
