Hey, just picked up a 200 Gal. aquarium(long) and I was thinking about going with an aggressive tank like I had before. Now that I've seen some of these well established paludariums online, I am definetly thinking about going that route. I need as much information and suggestions as possible.....basically anything that can help get me started. Just to give an idea, all I have is the tank and stand. I need suggestions on filtrations, whether to do undergravel or canister. Also suggestions on lighting, what type of environment would be hardy for a first-timer, different types of aquatic life, basically everything. How would I go about adding a waterfall? I have plenty of time, several months to get it set up and I am in no hurry. Also, are there any reptiles such as snakes that can survive in that sort of habitat? I know I read something about garter snakes but any info. that I can get would be a huge help. Also, if you have any types of links to informational sites it would be appreciated. Thanks.
