We have a 30 gallon tank with 1 Male Electric Blue Hap, 1 Electric Female Hap and a Red Zebra. Over the past 4 days we have noticed the male Electric Blue Hap (grey Fish) gasping for Air at the top of the tank. The other fish are okay . We are currently feeding them New Life Spectrum Lg. Fish Formula (pellets) and every other odd day using Complete Flake Food by Nutrafin MAx.
Any suggestion on why he might be gasping would be great.
Thanks
