Two side by side. The one on the left has a shorter snout, longer snout on the right.

Same longer snout one as above.


Another shorter snout one in the front, longer snout in the back in both pictures.


This is another that I picked up at a different time, I believe it to be a male as I also have a female (due to the gravid state) that looks identical, and the guy I got them from said they bred for him (and I believe they did for me as well b/c the female would go from thick to thin overnight). I'm under the impression that these are the 'dwarfs' as they're both 4" and haven't grown in over a year.

Is it possible that the shorter snout ones are hybrids, or just different species/variants and weren't from the same breeder? From what I see, it looks to me like I could three different fish here. The short snout (the dwarf petricola?), the longer snout (not sure), and then the adult male in the last pic (though not sure what he is now either).
