I have a marbled motoro that has lightened up drastically in color, almost whitish. Also I believe there may be blood in the stool.
The only change I have made is I added some sand that was from another tank that I baked at 375 degrees for 90 minutes to sterilize.
I have 2 in this tank. 75 gallons. I do 30% water changes every 3 days. They slowed way down on eating a while back. 1 of the rays has gotten its appetite back, but the one in question is still not eating like it used too. I feed them mysis shrimp and frozen raw shrimp after it is thawed out. I have contemplated trying live black worms to entice the one, but now that I have seen red in the stool I am not sure I want to go that route.
I have been keeping an eye on my water parameters and I am 0ppm ammonia, 0ppm nitrite, 20ppm nitrates.
The stool is so small it is hard to get a picture. Just wondered if anyone has seen this before?
Here are before and after pictures of the ray in question.
