I have one for a month in my care, no ammonia spike, foul smell, no death...................sodenoshirayuki;2851927; said:LOL i wonder who is really the thick headed one here...How about this, you go get yourself a "freshwater" atlantic ray, and then go put it in a tank and treat it as any normal freshwater ray and see if your tank starts smelling like a zoo.
rmkoonaquaticpets: I have a lot of these stingrays (Dasyatis sabina) and have had a lot of them for years...I keep approx. 50 rays in my 700 gal. tanks...these tanks have a bbfilter, a shredded pvc bio & a media filter / no problems. / problems arise if you do not control the nitrates and bacteria and fungus./ I must have a clean system at all times./ these rays are a lot different than their marine cousins...FRP .... long term, they will die in a small captive home tank. Urea ouput is baesd on the animals abilities to osmoregulate themselves in relation to the salinity of the environment the are in. Marine elsmobranches are very different in the way they pass waste vs. how freshwater fish do. People need to know that prior to getting one of these rays. Waste increase will be ten fold. So, if you need a 100 gallon tank to house a freshwaer fish of the same size, you'll need a 10,000 gallon for a FW Altantic ray.
So, in short, the FACT is that these shouldn't be kept in freshwater long term. To be kept RIGHT, they are saltwater animals. And just for the fun of it, how many pet trade Altantics are coming from the river vs coming from the ocean?
Sounds like a nice setup.rmkoonaquaticpets: I have a lot of these stingrays (Dasyatis sabina) and have had a lot of them for years...I keep approx. 50 rays in my 700 gal. tanks...these tanks have a bbfilter, a shredded pvc bio & a media filter / no problems. / problems arise if you do not control the nitrates and bacteria and fungus./ I must have a clean system at all times./ these rays are a lot different than their marine cousins...

this is terrible advice- you can not keep 50 of these rays in a 700 gallon tank for any sustained period of time - whether it is fresh water or salt water.rmkoonaquaticpets: I have a lot of these stingrays (Dasyatis sabina) and have had a lot of them for years...I keep approx. 50 rays in my 700 gal. tanks...these tanks have a bbfilter, a shredded pvc bio & a media filter / no problems. / problems arise if you do not control the nitrates and bacteria and fungus./ I must have a clean system at all times./ these rays are a lot different than their marine cousins...

I am not the smartest or best fishkeeper but I do know quite a lot about things and I have never head or seen anything about stingrays needing constant freshwater and what dose that mean new clean water if so wouldn't a filter do thatthey might NOT need saltwater in a river, but for AVERAGE keepers it would be easier to keep them in a 400g saltwater system than a 3000g freshwater system.
rivers provide constant freshwater, something we cant unless you have a drip system, that you wouldnt really consider a drip, more like a stream system.
