This is where I get aggrevated...this person is an experinced fish person, they sold me these guys, they KNOW what kind of set up I have because they are the ones that set it up for me...now what am I supposed to do with these little guys to keep both of them safe? Like I said, they are on opposite sides of the tank, I hope that is where they both stay...I am a huge animal lover and get very upset when people mislead other people about them! What should I watch for? Any help is greatly appreciated!
