I have a 150 gallon tank, and I have a female motoro stingray and I want a freshwater atlantic stingray. Could they go together? I know they will outgrow my tank.
 
well you can over filtrate to help break down the ammonia.. but you will need to do a ton of huge water changes in order to combat nitrate accumulation. The atlantic freshwater rays arent really freshwater, they just adapt to freshwater by producing more ammonia. People usually deem them sensitive and unhardy, but it's because they put them in water with low dissolved solids and they produce massive amounts of urea/ammonia and kill themselves in the process..

and the Motoro will eat all the food as they are a more aggressive eaters, and will completely stuff themselves.. so you will have to overfeed the tank in order to get the atlantic food to get enough food, which then circles back to the water quality issue..

They really do best in very large brackish/marine tanks..
 
I have kept them together in the past and am currently keeping a good mix of rays. I have marble motoro, atlantic, teacup, and humerosa rays all living together and they are all fat and doing well. Like it has been said, the keys are a large tank and excellent filtration.
 
read up on atlantic rays and you will understand... in order to be in freshwater... they create more urin to cope which puts water quality in the **** hole
 
Yeah - keep Atlantics in saltwater. When they are in freshwater, you are really over working there bodies forcing them to secrete far more than they normally would in the wild. Putting that level of stress on them makes them much harder to keep long term. Your ammonia levels will be through the roof as a side effect.
