I've only been a member for a few days. We keep some cool fish. 2 black arowanas, a tesselate morey, green spotted puffers, and lots of others that are less important to bring up here. When we got our aros the manager of the fish store told us that a stingray would go ok with them. he suggested we get one actually. We looked into it a bit and found a few reports that occasionally a ray ends up killing other fish, I'm assuming from feeling threatened. we also found that they all grow quite large. I see here that there is a lot of breeding being done. Very cool! btw!!! What size tank do a pair need at adulthood? I am assuming here they would be better off with a very large squarish tank to optimize ground space. There also seems to be lots of people here in New England that have a hard time deciding what is what when it comes to species. So if we were to go out to purchase a "teacup" we could end up with something that gets quite large. Just would like more info please and some opinions. I am not running right out to get one, but have always found them interesting. Also how do you sex them?!? (just for my own knowledge) There is the kid thing going on here (4 children) and we have rules about not owning exotic animals that see us as a food item, so for instance there aren't any crocs here, lol, no reticulated pythons, or burmese pythons, Can these guys be handled safely? We deal with the Black aros and the eel safely. Im thinking it is probably similar, you know don't be stupid, take necessary precautions. and thanks in advance
