when you have an olympic swimming pool size aquarium available for one let me know. Until then I still suggest its not a good idea..whether you are allowed to keep one is besides the point..... I have kept groups of adult sized Tigers....Brachyura make those look like tadpoles.
I have tried to import them. I could get a minimum of 10. I needed to place the other 8 (at cost price) and STILL I was turned down by several international aquariums that BUY other rays from me!...I can only wonder why.... I guess nothing to do with getting to be up to 1000lbs or 7' across or eating 3 cows and an elephant each day probably?
B's are also thought to be at least partly migratory, another problem that is impossible to deal with in an aq. Very little is known about them.
When I reach that point I'll consider it. It is in my plans. Not right now but I once i am in my house w/ my land(just a matter of timing) I am building massive displays. You particularly didn't say is shouldn't be available, that was t1. As well as a few others. Like you said you don't recommend one until x person has the pool.
As to being besides the point of ability to own them, that is the point. My first post was about how everyone all over say "x fish shouldn't be allowed in the hobby". If I have the money, will and the energy to figure out how to keep it alive I should be able to get a great white if I wanted.
As to the migratory possibilities. 100's of other fish we keep are at least in some way migratory. A prime example is an uncommon fish but present american eels. They go into full salt yet they are still kept successfully. One good way to learn about a species to am extent is to keep one in captivity. The other is to study it in its home. Since there is an almost impossible chance to follow them in their habitat captive fish will provide the best knowledge about them. There are many different rays that we don't know much about, but we learn so much about in the tanks.
As to feeding a large fish that is the least of concerns for someone like myself. I am an avid fisherman and the larger the fish I have the easier it is for me to feed. I catch all kinds of fish from redhorse to pike or walleyes. I feed them to my fish. I go fishing anyway I just keep them for my fish. The bigger the fish the less work it is for me prepping the food. When I can feed whole fish to my fish it is so much easier.
My only hold up right now is space. I only have space for one real display so I have been selling my gars to allow me to focus on my rays and aros. That is just due to me being in my apartment until I find my house.
The only thing we should be doing is encouraging research before buying. Not saying weather or not a fish should be allowed, you give the government an inch, they'll take your balls. The government patrols sites like this and get ideas for banning things. In the end the more they ban the more money they get in pointless fines and restitution.
