Glad to hear they turned around! Careful with Fluke tabs, they are not safe for many different fishes. BTW a single dose of prazipro is fine. Also Metrondazole and Kanamycin are safe as well.
In the future receive your rays into a quarantine tank and observe for a few days, just make sure water is proper and temp is good. Unless they are excessively thin (divet in forehead for example) try to feed for at least a week, making sure that the water stays clean, then entertain medicating.

If I was a new-born juvenile pup that was cast-netted out of the wild in Colombia just a few months ago... I would not feel any better about being placed on a bright white sand that would make me incredibly vulnerable to predators. White sands and substrates can be just as stressful as beneficial because prey type fish that usually live in dark murky waters, with dark based patterns, would prefer to burrow themselves in a dark substrate in a dark a murkey area.
I've never had an issue putting juvie retics on barebottom with a driftwood hide for them to go behind to feel 'secure'..
I have killed a ray from keeping it on a substrate that looks identicle to that which was supposed to be 'silica' free... I think it depends on the type and size of the ray.
These are the 2 arguments I always hear, "Rays are seen on fine sands like that in the wild and they come in contact with similar substrates in the wild..." - except for the fact if the substrate irritated the ray - it could just move locations. Not possible in a confined aquarium. They do the only thing they know how when they feel insecure from bright whiteness and irritation, burrow themselves, just making it worse.
The other argument is "but my Motoro lived fine on that sand"... I have a pretty strong hunch that large adults rays are not bothered by these types of sands. It might have something to do with slime coat production, not really sure. Either way, I have seen Motoros live happily on some very 'non-ray safe' sand, and so people use that as a generic basis of information for ALL rays.
One of the first Orbignyi we imported wasn't looking so hot, looked a bit stressed in the bare-bottom pond. I thought to myself "Hey this tank with this nice fine white sand is perfect he will feel so much better".. I transfered him, he curled and died within a half hour..
just my 2 cents
ps. Yeah the Fluke tabs ... I was wondering about that?

I will change the sand, (if and) when they uncurl. I like your thinking on the dark sand idea; very logical. The driftwood idea was very appealing, as well.
The story with the fluke tabs is that I went to the LFS to get some Prazi; the employee there (who actually keeps rays, quite a few beautiful large motoros) reccomended Fluke Tabs first. I checked the bottle and it had no warning at all about it not being good for some fish; once Mike alerted me to the problem I did a little research and found out that it is toxic to almost every single thing that comes out of the Amazon River. Any other time I would have checked MFK before buying medication, but this guy seemed to know quite a bit about rays. He didn't mention ever using it on his rays, but he seemed so confident about it. I was trying to take care of them, and I might have just doomed them. I'm pissed off at the guy for reccommending a medication without being aware that it was poison, I'm pissed off at the company who produced the medication for not putting that information on the bottle, but mostly I'm pissed off at myself for not checking.
I work in a job where death happens; I've been responsible for the deaths of other people, both intentionally and otherwise, but this is my first time doing something that might lead to the death of an innocent ray. I've never had trouble with it before, but I think I might lose quite a bit of sleep over this.
I'm hoping for the best, although I'm worried about how Ashley will feel if the rays pass; thanks for all of your help! I will keep this thread updated with how the little guy and gal are doing.

Military. War does something to you, but I've never worried like this. I mean, I know what I get myself into. What did these poor rays ever do?

Thadeus has been with us maybe a week; Tabitha has been around for a bit over a month, give or take. Ashley would know the dates (she is good with that sort of thing).
