"Long, thin bodied fish" - if you've ever seen one - would most certainly apply to juvenile socolofi. Any poorly bred or severely stressed socolofi may exhibit horizontal barring and even a vertical bar.
I've not excluded the possibility of P. elongatus as I've already stated, it's either a poor socolofi or a hybrid. socolofi x elongatus is definitely a possibility. I'd lean more towards a hybrid than a pure socolofi personally but since you insisted.
You can
think A. latifasciata all you want. Nothing's gonna change the fact that the vic in question is
not A. latifasciata.
cichilidfinder and Honda are correct in this situation. Hap. sp "Thick Skin" (sp. "44"). I can't see how anyone could further prove the argument as it's all layed out for everyone to see. Perhaps one last try?
Hap. sp. thick skin (aka sp. 44) may or may not exhibit red coloration. If and when it does it is
on the upper half of the body.
Fish in question (if OP does not mind, if so I'll be happy to pull the photo)
Let's forget for a minute any fin coloration, body base color, barring, body shape and pay attention to the crappy and hastily drawn figure shall we:
Can't seem to get it to normal size but whatever. Should be simple enough to understand.
Now let's look at Astatotilapia latifasciata.
