Its a nice looking tank! Aqua One do some nice set ups these days. I am a bit concerned about your fish though, that is a lot of fish for 240 litres. From a quick head count I get
2 Parrot cichlids
5 Severums
2 Geophagus Brassiliensis
2 Electric Blue Acaras
2 Regular Blue Acaras
1 Chocolate Cichlid
2 Keyhole Cichlids
1 Rainbow Cichlid
1 Satanoperca sp.
1 Geophagus Stiendachnari (I think in the middle?)
Red Rainbows
Auralis Barbs
Silver Dollars
Clown Loaches
Opaline Goruamis
Congo Tetras
Pleco (possibly a BN?)
Costae Tetras
Thats 19 cichlids in there, 8 of them can clear a foot as adults so will require a much bigger tank and the waste they produce must be sending your nitrates sky high? The territory requirements in there are massive and just too many fish to really deal with in what I think is a 4 foot x 15 inch foot print?
What are your plans with this tank? Is it to go bigger or split them up?
