Can I mix different species of shrimps? Will there be aggression or territory issues? How many shrimp can I put in a 5 gallon planted tank? Thank you. I just bought 3 black diamond shrimp (I think they're also known as bee shrimp?) and got a "bonus" tiny ghost shrimp that jumped into the net and the lfs gave me for free rather than try and get it out of the net.
