I just found this thread, and that's pretty cool. It brought back a memory of a letter I saw in Tropical Fish Hobbyist back in the late eighties. The caption on the letter was "Questions They Never Asked Axelrod." I don't know if it was supposed to be an April Fools joke or something (I don't think it was an April issue though), but the letter's author asked if he could possibly cross an arrowana and a neon. Whoever the columnist was responded that he would need a very large tnak and he needed to be prepared to go through a LOT of neons before the arrowana would likely find an acceptable mate. It was hilarious!
