I have a pair of Ophthalmotilapia ventralis "Silver Streak" in my 75gallon tank. Male is 5inches, and female is 3.5inches. I currently have some (5) 2 inch female Hap. Ahlis with them. All my water parameters are fine...Seems like just the male isn't eating though? He does not seemed stressed, i mean he chases all the fish around and even attempts to breed with the female (already building sand nests)... Is there anything special as in food that I can feed this guy? I'm feeding NLS theraA, NLS cichlid formula, and 100% pure spirulina flakes. Please any comments would be greatly appreciated!
