Well, most tanks are still Rectangles, and the filtration depends on what you're doing with the tank. If you're just planning on breeding fish, a big strong trickle filter with overflow box would be the best choice.

Has anyone seen these blue "panaques?" I know they're not really panaques, but that's what the LFS calls them. I was wondering what they eat exactly. I've kept a couple in the past and had no luck with them.

20 looks and no response? No one has kept a green phantom?

I've been looking at these for awhile and was thinking about getting some. I want to know what the parameters are for keeping these guys. Water quality, ph, diet, and max size would be helpful. Also, can I keep more then one in the same tank??? Are they aggressive towards other plecos?

Thanks.
