I would definitely add some caves and/or flowerpots to your tank. Try rearranging everything too. Hopefully the male will be able to establish a "safe" territory. Good luck.
Cool, Tim Bo that feeding technique was so obvious and simple yet the only thing I ever did to make the flakes easier to eat was just put a few large flakes at the top and wait a few secs and then poke them down into the water quickly so it would get broken up and slowly fall to the bottom. but i just tryed that feeding method and it certainly worked for the kribs, but the top feeders missed out. I guess i'll have to even things out....
