Also, that a regal has been eating there is one thing, but after a day or two in shipping it might just go on hunger strike for one or another reason. That's why I'm not to eager to have this kind of fish shipped around too much.
The Red Sea regal I got from DD never took a bite since I got it 6 weeks ago. I'm going to start tube feeding it this weekend and see if that changes its mind.

Excuse me? Force feeding. I hope it works well so you can teach me!
The bad boy is enroute and we will make the best of friends! And thanks for making me nervous about receiving a 6" monster that may go on a hunger strike.
I prefer Focus on the positive and the good success stories. Not the bad ones......even though from my research it looks to be a 50/50 odds at best. Plus I'm a quasi rookie so let's reduce the odds of success. This fish will be the staple of my reef for at least a decade. (Where is the praying emoji?)

A toroidal vortex for gamete dispersion in a marine fish, Pygoplites diacanthus

Short Communications
Toroidal vortices are a common result of motion through both liquid and gaseous environments. Their formation and movement are recognized as important in understanding the mechanics of flight (Weiss-Fogh 1977) and swimming (McCutcheon 1977). One species of coral-reef fish, the regal angelfish, Pygoptites diacanthus, makes use of this result of normal swimming to assist spawning success. During spawning, a cohesive, toroidal vortex of gametes is produced which moves upward in the water column, away from the potential predators which crowd the reef. This spinning ring of gametes is not known from other members of the family Pomacanthidae or among other fishes.
Spawning by P. diacanthus was observed between 31 July and 15 September at Enewetak Atoll, Marshall Islands, at several locations including patch reefs, lagoon pinnacles and lagoon-ocean passes. Each male controlled a harem of 2-4 females, spawning with each at dusk, from 15 min pre-sunset to at least 25 min after sunset. Courtship was minimal, the male visiting each female in turn, travelling well-defined paths. Females signaled readiness to spawn by rising up into the water column while spreading their pelvic fins. A male would then approach from behind, place his mouth on the female's side just above her gonadal pore and move his mouth in a nuzzling manner. The pair then spiralled slowly up ı89to 1 m above the coral before releasing the gametes and darting back to shelter.
The courtship is thus very similar to that of other angelfishes (e.g. Thresher 1982). However, as pairs ascended, the male left his position beside the female, dropping down and back until he was below and perpendicular to her body plane, though still in contact with her ventral body surface (Fig. 1). At the peak of the ascent and just as the gametes were shed, the male flexed his tail sending him downwards to the reef, simultaneously catching the gametes in the resultant vortex and sending them rolling toward the surface waters.
After release, the vortices rose with an overall speed of 0.27 m s -1, rising fastest when first formed and slowing as the rotational speed decreased with the friction of passage through the water. Initial ring radius (ro) was estimated at 0-05 m and expanded to approximately 0-5 m at 5 6 m above and 30-40 s after release. Vortices were still cohesive and visible for as long as 60 s after formation, elongating and expanding as the system slowed and eggs began spinning off the edges of the ring. If passage was impeded or interrupted, the cohesion was destroyed, upward motion ceased and a diffuse gamete cloud similar to that of other pelagic spawning fishes resulted.
Such a vortex, because of its motion and cohesiveness, has an effective or 'apparent' viscosity of ...
Figure 1. Pre-spawning positions of Pygoplites diacanthus showing the change in position of the male relative to the female to facilitate vortex ring formation. (A) After the male approaches the female and as they begin the ascent, he is beside and below her. (B) Just prior to gamete release, the male has moved under the female and perpendicular to her. (C) Just after gamete release, the male's tail has moved upwards to catch the gametes in the resulting vortex as he moves downward and back to the reef.
DOA. As you can see, there is a 1" vertical cut on his side. How in the world would this happen during shipping? Likely the box was dropped as the bottom was water soaked and the newspaper inside was a wet mess. I've requested a replacement so I am going to have to suck up the $66.00 shipping charge. Poor guy.

Sorry for the loss and disappointment - I think most of us have gone through this at some point.
It's hard to tell for sure from a picture, but that "cut" looks like a beginning uronema infection or a wound the fish had before.
A cut during shipment should be impossible - there shouldn't be anything sharp in the bag. Also a ruptured bag should require a seriously crushed box. If it happens just from dropping the box I would say the packing was insufficient.
Let's hope the replacement will arrive alive and healthy.

Had the same experience last June from there with 2 Red Sea Regals, fish ate but died after 3 days. Fish were accurate sizes but the misbar wasn't the picture I was shown.

The local store here got 3 new Indian Ocean Regal Angels in today, all around 3 inch in size:
1.

Seemed OK, but still not fully recovered from shipping. Also not as alert as I like them, but seemed to look for food. This was the smallest they had.

From the way this one was swimming it looked like it may have a serious problem - a bit thin too. May recover, but risky.

A little skittish still but otherwise this is how I like a regal to act.
I decided to take this one home.

6 - I may not keep all.
Plus it is still a very big question mark if the hunger striking Red Sea Regal from DD will make it.

If you don't start trying to force feed it, it stands little to no chance. Just have to buy the bullet. You will have to force feed it for several weeks twice a day before it will accept prepared foods again I'm sure at this point.

Sorry about your luck!
The one I got from him had the bag the fish was packed in, a few small bags of water and some newspaper with the usual styrofoam liner box. There was no packing peanuts and the main bag did not fill the box, so it must have just rolled around in there. Also the box and paper was so soaked with water, I made the driver call his supervisor before I accepted the package.
