Looking at yours Julian270, yours looks like a Cichla monoculus "Enviria Lake". If it turns out looking like the only photo on the web, how much you want for them?
OP's your bass has a short head and the shape is off for being a typical Mono and/or ocell. Also, the op's 2nd and 3rd picture the head looks like a orinos head if that. To be honest, I have no clue what OP's bass is. No one post any updates of their Putomayo's in a while or at all.
