I was taking yet more photo's of my Catfishes,they must dread seeing that camera coming out yet again,when i noticed my only has one pelvic/ventral fin.

I have been unable to find any ventral veiw photo's of P.armatulus and have been wondering if this is the how these fish are or is mine missing a fin.

I would really appreciate if anyone can answer this question as I'm really curious about it now.

Definitely missing a ventral fin.

It's a rule of thumb: if you notice something on a fish, look for the same on the other side

if the other side is the same - so the something is there, on the same place, similarly shaped - the something will most likely be natural, being part of how the fish is supposed to look

If it is not, it might be an individual variation, or a desease

This is especially handy looking at puts, which might be the result of flagellate desease, on the head of a fish arount the nose-holes and so on

yeap definitely missing a fin! but don't worry too much about it, as your cute lil bugger looks very healthy everywhere else, and considering it's gotten to this size, it means it has no trouble obtaining food! :D

Thank's for all the great replie's.

I have no idea if he has alway's been like this,but there are no other fish in the tank that could bother him so i think he must have and he dose very well for himself :)
