fin clipping

Any tips?
I'm about to do this with a live Synodontis sp to be included in a molecular phylogenetic project.
I'm taking the sample from the caudal fin and putting it in 190 proof everclear.
Just a little gun shy! Will the fin grow back?

Should grow back - I cut most of the hard ray of a Pimelodus pictus when it got stuck in a net, and a few weeks later, it couldn't tell which one it was...

yes indeed - soft finnage has IME pretty much always grown back in synos. Most of the hard rays in dorsal & pectorals too.

Thanks!!
I've got everything set up.
I'll be doing the "clip" when my assistant is available.

Well, deeds done.
That was nerve-racking!
The two fish sampled.

Ahh of course, this will indeed be interesting.

I've done it with Corydoras for the same purpose. The grow back fast, so I would think it would be the same with Synos.

Who for? What are they doing exactly?

I'm currently doing a project that involves molecular phylogenetics of Synodontis and if you could get a small piece of fin tissue to me in 95% ethanol sometime soon, I could include it in the data set out of curiosity. I have data for S. njassae and another Malawian Syno, so the analysis should give some idea of where your specimen belongs.

My favorite part of the letter, as I said to Dave not really surprising but exciting nonetheless.
