Hi everyone, I've been reading posts on this site for awhile but finally decided to make an account. I've heard a lot of mixed things about jars, some say they're insanely aggressive and some seem to be doing fine in community tanks, while others only attack fish that look similar/occupy the same part of the water column. Anyway, I'm hoping to house some black diamond rays in the future, in a tank about 96x48x30-36". I want an aro, but feel like I'd be pushing it if I got a silver or black, as I wouldn't want a 3.5 footer in a tank thats only 8x4, and, since I'm from the US, asian aros aren't an option. What do you guys think (especially those of you with personal experience) about a jardini with some rays in a tank this size? Thanks in advance for any input!
