I think its awesome that your getting into polys man. I think you would enjoy them.
Overall polys arent an aggressive fish. Out of all the polys that ive had tje only one that was truly aggtessive was an endlicheri "dabola". A coulple of other members reported the same behavior. Could be that we just got unlucky.
As far as which one its really in your taste and what your willing to do to obtain one. Ordering a wc one through the mail woukd allow you more of a selection to pick from vs getting one from your LFS.
Is this what you were reffering too ? View attachment 1278079
That is the exact one I was looking at. Thanks for posting the picture.
Here is my tank as of today:
It is a bit messy because this is about two minutes after I finished my water change. Also, I just removed my 2" pvc tubes because my biggest eel was starting to get stuck in them and it actually got a bit of an injury right around the anal fin area. That big eel really is a monster of a fire eel for how long it is.
As for getting a small one and growing it out in my 29, I kind of prefer it that way because I enjoy growing my fish from a really young age. I started my first two fire eels at 3-4". The only reason I got the third fire eel is because I couldn't pass up the red coloration it had.
I will probably like the lower Jaws better if they look more prehistoric. That look is what is drawing me into them.
