is a 4 feet tank size big enough to conduct captive breeding of stingray?
and another thing is most stingray are wild collected from rivers such as Amazon, am i right to say captive bred stingrays are more suitable and adaptive in aquariums & water composition?

i have read it before in books, that freshwater stingray have ancestry decent from their saltwater cousins. During the earth continental drift (tectonic drift) movement of the earth continents, has causing sub-divided oceans and rivers are formed from it, and water gradually looses it salinity level in waters further inland farther away from the ocean, some stingrays are trapped and become adapted to freshwater rivers over thousands of years in its evolution and survival capability. Some can even survive in brackish water, the area which the river meets the sea. Research has findings shows that bacteria that live in the digestive system of a freshwater stingray are the same ones that are found in those stingrays that live in sea water.

Guess that will answer why freshwater stingrays are sensitive to changes in the water in terms of salinity and chemicals.

Hi there nice ray you have, how do you tell the differences between the gender of ray? Male and female physical differences ??

i am considering keeping rays, and looking for those captive bred ones. If you manage to breed them i don't mind to buy a male and female sting ray from you. I think a 4 feet tank would be sufficient to breed them. I am from subang jaya. LOL.

you mean sting ray do attack when you handle it? you mean it bites your fingers?

the sting ray that killed steve is the big one, and live in sea water.
if I am not mistaken the largest of all stingray is the manta ray and grow up to 5 - 6 meters in wing span.
the size is very big and so wide the way it swims it's like flying or gliding through water.




look at the size of that thing compare to the diver
