Hi everyone I'm new to this board but not new to this hobby and I had a couple ?'s. I just bought a 12" marble two days ago and it start eating yesterday.I fed it shrimp two times yesterday morning and last night.This morning I tried to feed him but he didnt want to eat.So I checked my water and everything was fine but my PH was a little bit high could that be the prob.?
 
Your ray is proberly a little stressed out deu to transport and capturing. Feed hem at night it are night animals. If he eats you don't have a problem you can help him a little bit by rasing the temprature a little bit.

The PH was 7.0 now its a little higher and the temp is 79-80 and the ammonia is 0 and the nitrate is fine. I never had this prob. what temp should I put it to.and thanks guys :thumbsup:
 
bump it up gradually to the mid 80's to stimulate the metabolism ( helps the ray get hungrier faster ) . Other than that, the params seems perfect. I would just leave the tank and the ray alone, make sure its in isolation ( no tankmates if you dont want to risk stressing a new ray )and it will eat in a few days.


BTW - shrimp is frozen market shrimp or live ghost shrimp ? I highly recommend blackworms to newly acclimated stingrays. Its very nutrious and and has a very high chance of the ray accepting it.
 
i agree with redtail that new rays usually won't take shrimp.
live blackworms is a good first food until the ray gets feeling at home
 
yeah , make sure you drop some worms over his head so that he "inhales"
some BW into its spiracle to get a taste of eat without actually opening its mouth.

And relax... motoros are tough... just keep the lights down low, if the tank is in a high traffic area cover it in the meantime to help acclimate the new ray.
 
Take a black sheet and entirely cover his tank, I have noticed that helps alot with stressed rays.

Heat and blackworms, and they will usually pull out of it.. Usually a little aquarium salt will help alleviate stress as well. I have pulled a ray out of the beginnings of a death curl using the combined 4 steps..(Antenna ray to be exact, before FedEx shipped it to the wrong state and killed it :( )

Tankmates will bother him too, especially fast moving or bottom dwellers such as catfish, cyprinids, or characins..
 
Ask the previous owner what he was eating before. Are his hips showing?
