So I have noticed that I am no longer enjoying my tank. Sure I have some awesome fish but most of which i never ever see. I am already overstocked so adding new is not an option. I am thinking about getting rid of all of my reclusive catfish and tire track eel and only keeping the channel cat,EBJD,BGK and a baby lima. I would like to add one or 2 more cichlids that have nice color to increase the amount of activity in the tank. As of now it just looks like a some sand and rocks in water with no fish. Any suggestions on what to put in there?
