Thanks for that feedback. Those red severums look really cool! will definitely have to look for one of them. I like the catfish ideas, will have to try and find one of them. I have never seen them in fish stores around here. Would something like cory cats and glass catfish work well with the severums as well. I would think they would be large enough not to be eaten.
As for filters, I want to stay away from the hang on back filters. I have had them before and have never had a good experience with them. I found a eheim 2217 online for $120 that I might buy. Also a greenhouse and pond supply place I used to work for buys from a wholesaler that sells aquarium supplies and fish, so I my be able to find a good filter for cheaper.
