My goal is to have 10 bucktooth tetras in a 20g planted tank with a 20g sump to keep all filtration and heat and what not in. I also wanted to have part of the sump hold feeders if possible. I've had bad luck with diy "sumps" so far, I need advice and possibly a link to a diagram. Also what plants would be best. Is an over flow neccesary or can I use two pumps. Wouldnt mind seeing some pictures of others bucktooth tanks.
