I have a 40 gallon QT for observation that I set up about 2 months ago so it is newly cycled and not mature yet. It has gone through some of the uglies and has recovered as normal. Water chemistry is good with Ammonia at 0 Nitrites at 0 Nitrates 0, Phosphates 0.02 Calcium 415 PH 8.02 Alk 8.2. Ammonia, nitrite, and nitrate checked with an API test kit and the others with Hanna Checkers. I have been around for the past 10 years but this is the first QT I have used, unfortunately I learned the hard way as most people do. I keep the fish in QT for a minimum of 2 weeks and only medicate if there is a reason then they go to the hospital tank which I have not had to do yet. I keep a black mollie in there all the time to keep it cycled and also because I will see signs on it first which so far have been none.

Ok, now the mystery and the items my not be related but this is what is happening... I bought two small Tangs, one Tomini and one Kole, both were eating well and acting normal getting use to each other and the tank and of course me watching them. A week after purchase, the Kole's lips swelled up and it looks like it could not close it's mouth, prior it had been picking at the rocks like normal. So yesterday the lips swelled and it quit eating but was still swimming around and it seemed like it wanted to munch on the seaweed on the clip but would not actually go to it. Today, I wake up to see it on its side dead. The only thing I see is damage around its mouth, there were no other signs of infection, worms, ich, or anything else. The smaller Tomini is fine and the Mollie is fine as well and are not showing any odd signs. I took the fish to the LFS where I bought it to get their take on what happened and he was stumped too, internet search had some similar issues with some people saying they have had this and the fish recovered and others saying that their died within days, mine was the latter. So that is mystery number one, number two is I noticed tonight that there are 5 little yellow clear balls on the substrate next to my frag rack, I was able to grab one and put it in a test tube and it looks like a tiny yellow see through ball or bubble. Kinda like a fish egg but I do not see anything in there. The frags that are in there are random Zoa's, a candy cane, and a clove polyp. I replaced the Kole with a Powder Brown Tang today as I wanted to introduce the two tangs to the display at the same time. The display is 125 gallon 6' tank softie and LPS with plenty of caves.

The only thing we could come up with on the Kole was maybe an injury from darting into the glass or the rock from possibly getting startled or chasing the Tomini. Curious what the yellow orbs are.

Are the yellow spheres hard or soft?

My guess would be some kind of egg??? I've never seen anything quite like it.
 
Looks like that of a nassarius snail, but snail egg usually clearer, and could also be from a shrimp.
So question is . . . do you have either in your tank ?

No snails or shrimp but did add the clove polyp frag right before noticing them, could be fish eggs that were layed on the frag and fell off when I put it in the rack. That is the only thing I can come up with.
 
If there is something odd to happen, it will happen in my tank, I had an odd algae type of bloom in my DT that I recorded and showed my LFS and also Algae Barn, both said "I have never seen that before". The only way I was able to get it to go away was dosing with Hydrogen Peroxide then installing a UV sterilizer.

I had a similar situation. I brought a golf ball sized green 'thing' home from a snorkel trip to the keys. Now I'm 80% sure it's a sponge. But nobody could ID it for sure or show me a similar example in any science or guide books. I had only seen it that one time until a few weeks ago when we saw 2 smaller versions of the same thing.
 
Hey all! I woke up this morning to something similar in my tank ON my nassarius snail’s shell and a few others randomly on the glass. The strange this is these specific group of snails in this tank are constantly riding on each others shells and rarely go in the sand, so I doubt they are snail eggs- especially since they are not laid in the tell tale pattern. I am attaching a pic (please pardon the dirty glass, this is my 10g “experiment” tank and I’m currently letting algae grow out for copepods and my hermits). I recently used this tank to convert 1 panda and 2 mutt mollies, all female. I suspect these are unfertilized Mollie eggs that have been expelled, but I will keep a close eye and report back!

Sorry to revive an old thread, but I also found these in my tank. I noticed we both had mollies in our tanks so with a bit of digging apparently its common for this to be the equivalent of premature/abort for pregnant mollies. These are not something that fry will come from as they usually give birth to live fry rather than lay eggs, so it's suggested to remove them.

I just found a few in my tank. They are on the back-underside of my aquascape - get virtually no light.
 
I wonder if the soft yellow orbs could be build ups of uric acid or other internal substance passed by the sick fish prior to death.
