hi i am wondering which cichlids will try to bite your finger through the glass, bump or ram their face on the glass as if they are trying to tell you to get away, bite your finger if you are cleaning, or attack and chase tubes, scrubbers, and vacuums around the tank, i am wondering which breeds do this because i think they are cool when they act this way, thanks! and i hear that purebred midas act this way, it is interesting seeing cichlids act this way so i think it is awesome
