Hello mate. The first one is a lapradei, and basing on the colour gradient, could have been a Dabola / Guinean Lap. I have on almost exactly like it, specially in terms of colouration.
Second one is a nigerian lap.
For PBBs, they really are hard to tell apart but the most surefire way is 3 clean bars, the head shape (more
angry and bullet headed) and fin count. There are arguable cases as laps have an overlap with bichir bichir; scientifically (from published journals dated 1964 and 2003, so yes, old)
PBL
58-68 lateral scales
12-15 dorsal fin rays
13-16 pelvic fin rays
PBB
63-70 lateral scales
14-18 dorsal fin rays
11-13 pelvic fin rays
I am sharing my Dabola Lapradei specimen from Tinkisso River

Chillin with my pseudo "PBB" (16 dorsal fin rays, 12 pelvic fin rays, topic for another day)
