Perches, but not cichlids
Cichlidis are perces, with 2 characteristics an aquarist can see:
firstly, they have only 1 nasal opening, other perches have 2
secondly, the lateral line is divided into two parts, the frontal one bending up, the second remainng where it was: on the middle.
Perhaps closely related families of perches show these characteristics too, but these only life in sea
