music appropriate to the appropriate fish, or vice versa

...and south america would be rather fond of heavy metal as well.

first question i have to ask is what size of tank do you have, you need a large footprint to properly keep rays and i'm talking a depth of at least 30"-36" due to their potential diameter fully grown, Potamotrygonid systems need to be large... at least three times the disk diameter of the species you keep is likely to achieve the ones really more suited to home aquaria are

Potamotrygon henlei, (Castelnau 1855), the Bigtooth River Stingray. Likely the most commonly offered species of Freshwater Rays offered in the trade... due to beauty, maximum size (to a mere 14 inches in diameter). From the Rio Tocantins. Cond.s pH 5.8-7.2, dH 4-15, temp. 23-28 C.

Potamotrygon orbignyi (Castelnau 1855), the Smooth Back River Stingray. Amazon and Orinoco Basins. To about a foot in diameter, 2kg. Cond.s: pH 6.8-7.5, temp. 24-26 C.

Potamotrygon cf. reticulatus. Smooth back river stingray, to 35 cm. disc width.

some general info.

In the wild, Potamotrygonids are found in open streams and slow moving rivers of a wide range of water types with sandy or muddy bottom and submerged vegetation. In aquariums clear water and very little decoration suits them well.Softer (less than 10 DH), more acidic (pH 7.0 or lower) is best.Temperature should be high (78 F. plus) and consistent. You are definately advised to place heaters outside the main display tank (maybe in a filter/sump) to prevent breakage and damage, low lighting suits rays; I would only have it bright enough to suit you for viewing unless live plants are involved. Large aquariums are a necessity if keeping more than one as biting and fighting can occur between conspecifics and they can be highly territorial, people recommend not keeping them in systems under 100 gallons, you will also need a highly efficient filter as they like meaty foods such as cockles, beefheart, shrimp/prawns, worms etc. as always only buy plump healthy fish as they can be fussy to eat at first and be aware the are very susceptable to ich and internal parasites.

thats all i can offer in the way of info hope it helps
