I have a 55 gallon tank with 1 large pacasamus about 12inches. I have 2 small cichlids a Jack Dempsey and Green Terror, the JD is about 2x the size of Green Terror. Initially the JD was chasing the smaller Green Terror around the tank for about month. Now the JD has gone into hiding. he is extremely scared of me going near the tank. Which left the Green Terror with control of the tank. About 1 - 2 wks later both fish have gone into hiding. Both seem very scared although the GT will come out and at times let me near the tank. If the JD is out when i come around he immediately darts away from me.
Where do i start?
P.S. the reason for a large pacasamus is i used to have a large Jack Dempsey both of these fish i've had in this same tank for approximatley 10+ years.. recently the Jack Dempsey passed away.
