Even so, knowing what was there would narrow down what & where these fish are and
come from.

Many do.

What does this mean? It sounds like your describing the basal insertion of the
dorsal fin and the change from spines to rays in it. This is the same in all
apistos.

Many species do this, especially those of the regani-, Rotpunkt-, steindachneri-,
and macmasteri-groups.

This description could match a dozen different species. Knowing what kind of
lateral band it has would be helpful. All apistos except A. nijsseni show a
lateral band at some time - even nijsseni does as juvenile fish. Does it have an
abdomonial markings? You don't mention a suborbital stripe, so I assume that it
usually isn't visible.
Now for my best guess (and that's what it is right now). The round tail without
pattern, low even dorsal, no lateral spot, oddly shaped caudal spot (a horizontal
rectangle), indistinct suborbital stripe, black edged fins, & dorsal spots with
red patches between them all point to A. sp. Rotpunct. This is a fairly variable
fish, colorwise. Check the following web site and see if it is simiar to your
fish: http://www.thekrib/Apisto/A-sp-puerto narino.htm#0
If this isn't the fish, I'd suggest you give them a couple of month to mature and
try me again. Hope this helps.
best wishes,
Mike
