Some nice entries this month and one that could be controversial! It is an acknowledged pic and it doesn't say that the P needed to be alive! May have to update that for future comps.
Anyway, voting will end Sunday 25th. Good luck

Voted! Good luck!

Good luck dudes

Good luck all. I wonder how the dead P' pic is leading the poll.... I mean no offence to anyone but I don't like it at all, its blurred.

Cheers.

Sounds familiar, though it's not a "best camera" competition, is it

can some one tag the organs and re post it

Schulte already published an answer to that, based on Axelrods photos :

Blimey, close one already this month!

Voted.
All good photos, Interesting last one

So at the end of this contest, I guess it's time to give everyone over here a word of respect. I had expected a much "heavier" attitude towards the last picture. Respect to all that considered it controversial, but didn't judge on it (yet).

Let me explain the story of that picture. Lately one of the Dutch members lost his S.eigenmanni due to a swim bladder problem and I realised I just wrote a post on the bladder itself, but that I absolutely did not know about a cure for it.
Now for discus fish there is an experimental cure that seems to work pretty good, but whether it could be used on piranhas or not, was something I did not know.

So first of all I asked Frank about the bladder condition. Roughly, most fish have either a physostomous condition, or a physoclistous condition. On piranhas however, nothing could be found and Axelrods drawing was not really clear on it.
Frank could not answer that question yet, so in the meanwhile he asked a friend from the Smithsonian institute, I decided to get one of the dead specimen out of the fridge to check for myself.
A while later, Frank confirmed that it's a physostomous condition.

So, all in all, it was a dead specimen thet I had not preserved on formalin yet and I sliced it to see if the possible cure for discus fishes, could be applied to piranhas based on the way the bladder is functioning.
(And that method may be working on piranhas as well !)

So once more, respect to all for the way you guys reacted on a picture that indeed would have been considered controversial on most forums.

Oi Curly, lost your keys ?
This should have been closed last sunday !

Congrats to picture #2
