Hi all. I am getting ready to move and will be setting up a 265gal freshwater tank. I was previously useing it for a saltwater display. My first question is about filtration. With the saltwater I relied mostly on livesand and rock. Currently I have an UGF and 2 emporer 400's will this be adaquate? My past experience with freshwater is limited to mostly 10gal. tanks, so any ideas on themes for the decor will be greatly appreciated. My next question is in reference to fish selection. I would like a community tank with a lot of color and contrast with out appearing crowded. I am also planning to utilize some type of invertabrate as scavengers, either crayfish, crabs, or shrimp.
