identification Sciaenochromis ahli or Sciaenochromis fryeri

Struggling to identify one oof my fish, since I have got photographs
of both ahli and fryeri and they can look very similar, shop that sold
it to me wasn't completely certain as they took it off someone as it
was getting a bit agressive, I found that when it was first put into
the tank is was fairly shy (the tanks is dominated by a 8in venustus
who does a good job of keeping order), but when I did a recent
reorganisation and introduce three fish that had a lot of blue he when
through a major character change - at present its in isolation and I
will reintroduce it in a couple of weeks to see if this takes the edge
off his agression


The firsh is an attractive darkish metallic blue, with a whitet strip
running from above the eyes to to top of his tail, the anal fin is
showing some colour but not yet very strong, fish is about 4in long.

When scared it burrows into the substance, if that helps.

With regards
