Matto Posted February 21, 2009 Report Share Posted February 21, 2009 my angels have had some jaw locking and so have my Nicaraguan cichlids what does it mean are they angry with each other or is it a courtship thing? thanks Quote Link to comment Share on other sites More sharing options...
ryanjury Posted February 21, 2009 Report Share Posted February 21, 2009 Aggression or breeding type thing.. It is generally a show of who is stronger, when breeding it is to see if ones mate is strong enough to breed with (natural selection only the best will breed), with dominance it is deciding who is stronger so they become the boss of the tank. It is usually harmless but watch out for any damage getting infected. Quote Link to comment Share on other sites More sharing options...
