We recently acquired a 55 gallon tank and have set it up on a stand and gotten a filter and rocks and faux plants and hides etc. we filled it, put water treatment in and let it run for 24 hours. Being an over zealous tank owner I now believe we added the fish too soon. We went after 24 hours and bought a 6 inch hybrid cichlid for the tank. We acclimated him in his bag for 15 minutes, and then put tank water in his bag and let him sit another 15. We then put him in the tank. He seemed fine yesterday, swimming around and rearranging some stones in the tank. Today, however he is in the corner at the bottom not moving much but still alive. I tested the ph and it is about 7.5-7.6. Can anyone tell me what to do now to help save the fish. I know the ph is on the high side, but before I add another drop of anything, I want to make sure I'm not going to screw up (again). Thanks in advance for any help.
