I've been debating the possibility of getting some lily pipes for my tanks. I'm trying to figure out which outflow is best for a Tanganyika tank. It has Julidochromis on one end, and Multies on the other. I need to know which lily pipe would be best. It has to put out enough flow for the flakes to sink to the bottom on both ends, but not so much current as to give them any trouble. I also need to know if there's any acrylic or stainless steel ones in the poppy style, I'm upgrading the filter on a 90g Oscar tank, and glass is not a good idea.
