Hi , here are my young bunocephalus, the "pink" guys I asked before look like amazonicus, and the ones with color look like colombianus what do you think? I am feeding them on live blood worms, ispods gamarus,pellets for shrimps(the kind of shrimp farm pellets) and otto bottom feedes pellets

Did you see this topic?
According to Steve, B.columbianus can be ID'd based on the higher number of anal fin rays compard to other Bunocephalus. Did they all come together in one batch? Nice collection there

Hi Martin, Yes they came from the very same shipment, I guess they are beeing breed somewhere on south america, perhaps colombia or peru since the fish market in Mexico only imports from those countries, they are big now they are almost 3 inch they arrived at the size of 2 inch I will buy some more soon sinces I`ve seen a shipment of hungreds of them but only an inch long, I want to breed them do you have any experience breeding them ?

I'm pretty sure they are wild-caught, not captive bred.

It is not possible to breed them ?

That's not what I said - I just don't think they are easy enough and valuable enough that commercial breeders do breed them. That's absolutely not the same as "can not be bred". It is certainly my understanding that they are comonly wildcaught. A Colombian exporter has two forms on the list, they come in bags of 300-500 and are about double the price of an Otocinclus for the less expensive, and about 6x the price of an Oto for the higher price one.

Thank you very mutch Mat

These also look like B. colombianus

The one species on the list I have is B. columbianus (of course, what you actually get in the bag may not be what the list says, but at least it's from the right region to be correct - the same list has L059 on it, which I'm pretty sure is the - much more likely to turn up in Colombia than a fish from Eastern Brazil).
