Megalonema orixanthum

[Rpul]

Are you seeing any growth on the length of the pectoral fins?
I wondered from the origins photos if they might have been damaged. The last photo seems to show the fish on the left with slightly longer pectoral fin now
I ask since Megalonema Orixanthum and Amaxanthum both have extended pectoral front lobes as blackbullhead says, but I still think these could be Orixanthum as you originally suggested.

If anything. I’ve noticed the dorsal fins seem longer and thinner then the original pictures.

They look very similar to a pim I caught out in Suriname. Yet, I’m not sure exactly what they was. So, this helps very little.
