Pair Of Cichlid's For A Community Tank?

[matt_99]

Hi all, will be as brief as possible... got a community tank as per below, and after getting a good group of small fishes, we would like either one large, or a pair of fairly large colourful, peaceful fish to be tank centrepieces.

48 x 15 x 16
Tank is 24/25 degrees
150-200 g/hour in tank filters
small rounded pebble substrate
PH 6,8-7,4
tmperature is 24/25 degrees
Hardness is normally 7

Currently stocked; 6 longfin zebra danios, 8 rummynose tetra, 6 peppered cory, 10 platys, 1 bristlenose plec and 1 albine bristlenose plec.

Thanks for any suggestions...

Matt
