so i have a question. what kind of fish are blue gill? i have always thought they were a type of cichlid. i need to know because my little bro caught one and has it in a tiny tank, and i want to take it to my house and put it in my 55 gallon.
I dunno if you would consider their relationship "close"...a good chunk of all bony fish are in the same order.They are a Centrachid or Sunfish. They are pretty closely related to cichlids (both are in the order Perciformes). A couple external characteristics to distinguish them: cichlids have 1 pair of nasal pores (nostrils), sunfish have 2. Cichlids have a split lateral line, sunfish have a continuous lateral line
