Well, Im sure this is the right place, since I need to know RIGHT away what I should do. I recently upgraded from a 30 gallon tank to a 75 gallon tank and bought a couple new fish. I orignally set the tank up for a polypterus delhezi and then noticed that I have this huge tank and only one fish, so I went out and bought another Polypterus, this time a senagallus. When I was there I also seen a african butterfly fish and got that with some floating plants also. The senagallus and the butterfly fish both use one floating plant and sometimes sleep on/beside each other so thats not problem, and the delhezi is pretty anti-social and just hides in the bottom where its not visible. I then bought two angelfish, and one just died today
. I then went to the pet store to check if they had anymore and to get crickets for my butterfly fish. They are getting an order next week, so I was looking around the tanks and noticed the most adorable chiclid (Metriaclima estherae) and had to get her. She (I believe its a she since its a yellow-orangish colour) its only about 3 or so inches big and constanstly chases my angelfish around the tank. I can already notice a difference in the angelfishs behaviour as its going places it hasnt before, and runs whenever the chiclid is near. So my question is... Should I wait to get my other angelfish and they will be fine when there is two? Or take the chiclid back (Even though I love it)? Or take the angelfish away from that tank that its been in for 2 weeks or so and put it in a whole different tank with another angelfish?... I dont know what to do and need help as soon as possible

? And would the M. estherae be good in a 30 gallon tank, would it get lonely? and rougly how much time do I have until I HAVE to remove the Cichlid, because I wont be able to get anything for the tank until tomarrow around 3pm, unless I can do it between my classes at like 11am
