sting rays

i dont really see the allure, you have to feed them live blood worms, cant put much else in with them, and then dont really swim that much, but anyways, i belive they need salty water and cost around 60 dollars

yes my friend had one that was about 5-6". hes not too smart about fish and had him in a 30 gallon fw with a lot of other fish. needless to say he didnt last long. and btw one of the reasons probably was he never got feed anything special like bloodworms, only flakes which i dont know if he ate. and yes he was around 60 bucks locally.

Most common ones kept are Motoro's - http://www.dcpaleo.org/Leisure/Animals/FishesStingray.html

and Teacup's -

But, I'm pretty sure any ray with the genus Potamotrygon is a fresh-water ray. Some just get bigger than others. For a ray tank, footprint is a lot more important than height, you'd want something minimum 2 ft deep for the smaller ones.

they are cool. and they do swim around a lot. ive seen videos of them attacking and eating crayfish. if your new you should start with hermorosas. most teacups are probably them. you start them off on blackworms and stuff then switch them over to nightcrawlers and raw shrimp and can even get them to handfeed. they need really clean water and you can keep non nippy tankmates or some top dwellers with them. im setting up my 90 gallon right now for a pair of humerosas. i know i guy selling them for 60 bucks each. with a 2 week warranty.

I've never kept them, but have done quite a bit of research because they are a goal of mine for someday. What I've found is basically, sandy substrate is a must, excellent water quality is a must, and they need meaty foods. blitzen25bm summed things up pretty well. For me personally I would go with a 2ft by 6ft tank minimum, the standdard 90g has a bit small of a footprint, and a lot of un needed height, but if it is what you have it could work for the smaller ones. One of the local LFS's here in columbus has a stingray display tank, and they do have some fish in with them although not many. With a 90 I imagine it would look pretty empty unless you had something swimming around above the rays. Let us know if you get them and how it works out.

i PMed you info for the guy im going to buy from.

my tnaks not really 90 its a weird tank. something like 5x1.5x1.5 buying them from 6 inches so they can hang out there for a while.
