You know what, not to down on you but I think those are Anabas testudineus aka climbing perch.
I have seen both species at my lfs and I was trying to figure out the differences because they look so similar.
I have been convinced for a while that they were the same fish but I did some research after seeing your post.
This is a cousin to the ctenopoma family.
These fish actually have a lot more character than the real ctenopoma kingsleyae though.
it turned out now, that 3 are kingsleyae and 2 ore ocellatusOh and impaid around 10,00 for each, so it was a good deal
