Can you put two males together (10" and 9")? I just found a awesome looking marble that I would love to add but just want to make sure this will work. Tank is a 180 until rays get a little bit bigger.
I think some may tell you that you might get say with it in a very large tank but it is bound to end in trouble as they mature, especially without a group of females to distract.
Wait for a nice female when you get your bigger tank.
i've tried to put 3 other rays with my 15'' male and he doesnt wanna have it. He chews the new tank mates instantly. It's worth a shot if you have another tank ready to go when things go south. You will know in about 30 seconds if its gonna work or not. I dont recommend it if you do no have the accomadations of another tank or a tank divider?
