Are shrimp and smelt very fatty foods?
Also keepin, does your armatus go to the top to gulp air alot?

Alot of good points being brought up. In my case, rays seem to be very healthy and constantly breeding. My rays dont ever go on eating strikes unless ph moves very far very quickly... Yet with the same diet and water conditions my old armatus were dying.

My rays dont go on eating strikes... The only ray i really had issues with were my flower, and my p14 when they were pups.
I have had pups born in my system, but never any nice rays only motoro.
Trev,
He may do it occasionally (it may not be gulping just chasing) he likes to swim the tank fast and show off, and scare everyone everyone.

Shrimp and smelt both contain thiamanise. Something the fish they eat in the wild may not have. I know many of the native fish around here do NOT contain it, but not sure about the fish down south.

The air gulping...... Thinking low D.O.? (dissolved Oxygen) I've already looked into the meters for it and they aren't cheap like conductivity and PH ones are. :( But might still be worth getting even if it is just to rule the O2 thing out.

I've had nice Marbles born in my crap water, but think maybe the crap water could have something to do with the crazy low litter numbers.

Maybe some rays have more trouble with certain water conditions then others? My blackies and Falks always seem great, never seem to have near the troubles with them as I do with the Marbles. The Thai guys actually report higher litter numbers in PH closer to 8. Maybe cause it's less prone to swinging? My PH NEVER moves. IF your guys' does obviously the water is softer and likely lower TDS/Conductivity.

Rays are tough, I think most of us agree on this. But if the water is too much for certain kinds, I'd think it could be too much for certain fish. Am I crazy for thinking Flowers and Armatus's track record in captivity could be directly related? Possibly a sign of water instead of diet being the issue?

The guy that had knocked up Tigers in his home aquarium always shot for conductivity readings of 100-200. His Discus bred like crazy.
 
Here is a link to that article I posted before which has a nice list of fish, marine and fresh that contain thiaminase and don't contain thiaminase. Also has a short list of crustacians And inverts. Its not a complete list as that would probably take forever.

I have actually thought about D.O. being the issue with flowers... Maybe armatus. I would get heavy breathing occasionally pre- UV...
UV supposed to have effect on redox.

I still think Most armatus deaths are damage to their head! To big, powerful, and delicate!

Fang got scraped in the eye by a stingrays stinger but My two smaller armatus never showed any signs of trauma to the head. And seemed odd to me that they died so young. They getting fatty liver disease or something? Maybe this problem is also why scombs die early.... Maybe we should only feed them twice a week when they get bigger?

Leads me to think its a mixture of water params, diet, environment, tank mates, etc...
