Can I keep 2 teacup stingrays and 2 peacock bass in a 135 gallon aquarium?

Not on the bass. The rays could survive in the tank, but not optimally. The problem is the 135 gallons are only about 18 inches front to back. The Teacup gets at lease 15 inches in diameter (not counting the tail) with some getting larger than that, with the tail length totaling up around 30 inches. The bass gets up to about 20-30 inches! As an adult it could not even turn around.

Note: The rays are not Motoro rays. They are a different species, Potamotrygon Reticulata. The Motoro is Potamotrygon Motoro.

The 135 could house two juvenile rays for some time, but a wider tank is needed for the sub adults to adults. You want a minimum footprint of the tank being about 72" by 30" or more. The 135 gallon is 72" by 18". A 180 gallon is better being 25 inches front to back. A 300 gallon is one of the better tanks to get as a standard is 30 inches front to back.

So, the tank is just too narrow front to back to optimally house either fish for life.

    That might be enough for one of each, but not two of each.

    You should narrow those down to 1 of each, not 2. That will probably work. Just make sure you have sand or fine pebbly substrate and the right foods. Also, plants (preferably live) and places to swim through and hide may help and make the fish feel more comfortable.

    There’s no such thing as a Teacup Stingray, they’re just baby Motoros which still get too large for an average 135 gallon tank! They need custom built tanks or tropical ponds are better.

    Peacock Bass will also grow out of your tank, they’d need more like a 250-300 gallon tank or larger. They get huge.

    edit: Technically anything sold as "teacup" ray could be Motoro or other captive bred species like the Retic, just a juvenile. If the store is using a name like "teacup ray" then chances are they have no idea what species it actually is.
