What is a sure way to distinguish between the Zebra Obliquiden and the Haplochromis redtail? .I recently Purcharsed an alleged "Zebra Obliquidens". A male with nice gold and red coloring. However I am aware The redtails and Obliques are often mislabelled. From what I've seen both species look almost indistinguishable, In my opinion. Any obvious way to tell the difference? I will post pictures shortly.
