My cichlids all have their own part of the tank and defend their territory from others. Everytime I do a water change i been moving the stuff around to see how they would react. My yellow lab loves this skull i got and he hides in there all the time, but if i move it to the other side of the tank hes afraid to go for it because of the socolifi. I was told also you will have one fish in the tank that is the leader but i don't think that is true in my tank. For wks my yellow lab was the leader now it switched to the socolifi. Anyone else try moving things around alot to see how they react??? I love watching them work and switch places on the leader board. Very awesome fish. Im still new to fish keeping but i would have to say cichlids are by far my favorite fish so far. I like my community tank but my cichlid tank i could get a six pack and watch for hrs.
