Male Blue Gularis Killifish (Fundulopanchax sjostedti) (Hard to Find!)
Rarely, if ever will you see them for sale. My breeders came from a chairman of the AKA.
They can live in a wide range of parameters soft and hard water. I have kept as low as 64F and as high as 90F. They make a great community fish as well as long as given some space and not overcrowded in a small tank and with peaceful fish as well. Very personable fish and have even trained to swim in my hand to be petted. Even with the name like killi they are actually peaceful fish and should be kept with other peaceful fish.
