Just found this thread after doing some google research on 4 of my bronze corydora group , I added them a while back off a trusted source , I don’t even go and pick my fish anymore I just tell him what I want and he drops them at my house , they were tiny baby’s probably under an inch months on they are bigger but not bigger if that makes sense they look like heads with fins , really short body’s , they swim they eat they are part of the social activity among the group , have short body corydora snuck into the hobby or is this natural
