THE ONLY FISH I WOULD REMOVE IS IN PHOTO NO: 6, YOU DONT NEED TO GET RID OF THE REST. PUT PLENTY OF ROCKWORK IN FIRST AND SEE HOW IT GOES, A TANK WITH NOTHING BUT YELLOW LABS IS BORRING. whats the point in having a cichlid tank if you only keep one type of cichlid.
in a tank of 1 metre i would probably keep about 15 fish, with plenty of filtration.
