I asked for 2 male and 2 female fish, and the assistant was confident she could sex them and pointed out the wide, short, hairy noses of the males compared to the thinner longer noses of the females. They're all about 4" / 100mm SL.
Now I've got them home and they have settled in, it was immediately apparent that one of the fish was different. Not only was it much darker in colour, but its behaviour seemed a little different and maybe a slightly different shape too. This darker one appears to have 3 rows of belly scales and the others have two.
I have quite a lot of photographs, but can only attach 3 at a time, so over this message and the next one I will put a belly pic of each of the four fish (they were briefly all on the glass at the same time), plus a comparison of the colouration.
Can anyone point me in the direction of an ID for these fish?
Many Thanks,
Paul M-B
P.S. in other happy catfish news today, my first ever fry have come from a Cory melini spawn
