I have 2 yellow labs (1 male 1 female), 1 girrafe (female), 2 blue malawi one's (sorry i dont know the name)(1 male,1female) pleco (unk), and blood parrot(female). Sorry about the pic's. Not that great of a camera phone. But i think that it was my electric yellow's that had them cause last night one of them had the black streak on the fins. I will try and get the wifey to take some pics with her phone and get them up soon
