okay, I was at my lfs today and he has 2 polys in one tank, one is what I though to be a sengal, looks EXACTLY like my sengal, but he swears it's a p. cong. and then the other poly in the tank is labeled as a extra large dinasaur eel, but it's CLEARLY not a sengal, it's almost black. He wants $60 for the large sengal that he's calling a p. cong. and $20 for the almost black "mystery" dinasaur eel. Now, here's my question, I only have a sengal, so I don't know what a p. cong looks like, but could it be that he just has them switched around, or do those really look just like a sengal, and do you have any idea what kind of bichir the really dark one could be? I asked him to hold it for me until friday so if I do end up getting it ($20 seems like a steal for something that isn't a sengal and 8" no matter what it is) I will post pics for a postive ID, but I was hoping you guys could at least point me in the right direction while I'm trying to figure out what this thing is....
