Locked fins?

[1journeyman]

hello all,
Well, just got back from vacation. Had a friend feed fish and top off tank for me.
All looks good except for one of my Green Chromis. It is not schooling with the others and has it's pelvic fins "locked" forward.
let me try to explain that... Normally when the Chromis are swimming around their pelvic fins lay flat along their bellies. They "flare" them out to flash each other, maneuver, etc. This particular one acts like it has lost control of the fins and they are stuck flared forward.
Any ideas? Fish have been in the tank for months. Recently added 3 Blue Reef Chromis, and a Purple Firefish. QT new arrivals for more than 30 days.
Salinity is 33ppm (Refract)
No ammonia
No Nitrite
No Nitrate
Temp 81-82

How is this fish doing aside from this? Have a picture you can post?

Well tried to get a photo, no luck.
Fish is not at all interested in swimming in the open. It's resting against back of tank, with head oriented slightly upwards. Seems to be breathing a bit heavier than normal. Seems interested in food, but doesn't actively persue it.
The most odd thing, as I said though, is that the two pelvic fins are flared straight forward.

Fish died sometime last night.
Thanks for your attempted help Beth.
All other's are healthy. Hoping it was a genetic abnormality or internal disease that couldn't be prevented.

Does it keep saying it is tooo big?? If so go to photo shop and size it down. Go to image and punch in 500 and it will put it at 130to190 and then you can post it.
