Hmm,no one asked me!
This fish is shown in my 2006 Safaris Pics.
Pseudotropheus sp. elongatus "yofu bay" at Likoma IslandB.jpg)
Obviously fairly common,,,if it has a Noth American distribution.
Up here a few years back it was the elongatus from Ndumbi Rocks which is located just outside the mouth of Yofu Bay.
In that case (Nudumbi Rocks fish) the females were yellowish/biege/golden.The males looked similar to the ones at Yofu,but they were fairly easy for me to tell apart.
Both fish are often called Ps.sp.elongatus "likoma",,,which is basically correct,but Ndumbi Rocks is not part of this Island and the fish are only similar.
Each bay and pile of rocks around Likoma Island would have a similar colored Elongatus but may differ slightly.
Hope this helps!
