Thanks all,
The water level is higher now, it was low while i was first setting it up and working on it just incase something catastrophic happened then there'd be less water to get up off the floor. it's up to lid level now.
The Cichlids and the Aro get along fine, it's a suprisingly peaceful tank considering the fish that are in it! There doesn't seem to be any one dominant fish, the GT picks on the Jag, the Jag picks on the RD, and the RD picks on the GT so nobody wins. The Red tailed shark seems to be the most aggresive in there but he just harrasses the dollars and pacu. None of them are silly enough to bother the TSN.
