I disagree
I don't think they ever curled, or they would be dead by now.. acting irritated? yes... curling? Nah.. my retics do the 'fake' curl all the time and I finally decided they use their back fins sometimes as rudders in the water to help hold themselves in place in the current..
They were on the same system, so I doubt it was water parameter swings.. the stress of being netted? maybe.. the likelyhood that burrowing in sharp silica/glass/fine sand and having it get in the gills and spiracles? pretty high..
You dripped them after import? no wonder they died..
Doomed from the get go.. how long is the flight from Colombia to where your at?
Its funny I move rays around all the time.. I imported rays into a 7.8pH and dumped them straight into the water, no drip acclimation... only lost 1 out of a few hundred, (within a few hrs of import) and it was already curling in the bag. Link:

IMO, it depends on the quality, size, sharpness of the sand..
so yeah it does matter.

Yeah I remember this thread

did you ever see my reply..

Nice Pleco in your avatar

Do you even keep rays? LOL j/k C'mon Anders

try and keep up..


After a 40-50 hours flight/trip to me, drip is a very good idea.
Also, the water was only 20-22 degress. And the tank water were 28-29.
So I dident want to give them a huge chock. Also, they deathcurled after being added to the tank. There were no sign of them curling, before they where added. And there were no ammonia or nitrite in the tank (or sand).
And funny enough, as soon as they where added, the curling began.
Also, i have stated from the start that her rays are just showing normal sings of stress, NOT deathcurl.
Also, about the flowers. You just said "flowers" like they are the retards of the stingray world.
But its kinda funny, they all death curel just after being added to the tank.
And its the same story with, rectis, orbignyis and so on (only happens with very weak rays).
Its the same story with newly imported altums. Change to much water and they all die.
Also, rays have a very thik slime coating. Just how is the sand gonna come into contact with the rays skin?
Also, the rays i imported almost 14 days ago, are all eating and getting better day by day. But 70% of them are STILL lifting their disc. AND THERE IS NO SAND IN THE TANK.
Now, her rays are still "curling" a bit. And it must be the sand for sure.
because changing tons of water and adding lots of medicine is not stressfull at all.
Oh, and i have a friend that keeps geophagus in a tank with sand like that. And these guys filtrate the sand through their gills. And for some strange reason, they are all still alive.
