I would buy one in a heartbeat, but It seems harder to find than a planiceps. There is one memeber that has some pics of some larger rtc x tsn on here somewhere. I remember seeing it a while back. They looked huge and awesome. Like a green rtc with lots of spots. They were very thick bodied. here's a pic of a large pseudoplatystoma tigrinum. i think if you put it in a low lite tank and took the pic from above you would pretty much get the tsn in the second pic! I wasn't trying to belittle you so that you know I just thought it was amazing reading this post again and seeing how much more we all know now!
It can be a bad habit for nature...
