Do whatever you want.... It's a free country. It's a hell of alot easier to say whatever then to concvince you otherwise when you have clearly allready made up your mind.....
I enjoy having peace of mind knowing that my fish have plenty of room and in turn the larger volume of water also makes it so I only half to do half as many WCs as someone who's got a tank half the size.... Plus I get the luxury of adding more fish if I want.
I'm not about to get into another pissing match about the max size of Odoes. I'll be more then happy to measure mine when they die..... And if the "myth" holds true my Odoes will be 10-12 inches.
4 footlong odoes, a 12-18 inch Lima, and a bunch of Bichirs IS one hell of a bio load. Might wanna keep that in mind before you get stuck doing daily waterchanges to keep the water decent.
