I'll bet they didn't survive because of the pleco, plecos are notorious egg, and wriggler eaters, and they tend to do their snacking at night when cichlid parents are sleeping, and you wouldn't notice.
And if the cichlid parents know there is a fry predator near, they will often eat the eggs and/or fry themselves, rather than let a pleco or anything else get them.

but they really aren't good parents,none of their fry survives like the gt pairs fry, and I have 9bn and1 common plec in the tank where the gt pair are, but find over time the fry just gradually disappear,prob down to what you said,with the pleco at night etc, but the jd's, just seem to leave them and the fry disappears quicker than what my gt pairs fry did, so they aren't good in that sense
