There are plenty of hiding spots. I put the senegal in with the del last night. He kept swimming up and down several times. the next morning i couldn't find him. (note there is a divider in the tank) and i found him BACK on the dat side with the smaller senegal. so i moved him back to the del side and he jumped back AGAIN!! So i will just see how it goes and if he bothers the little senegal too much i will put the big sen over with the del AGAIN
