I have a 40 gal tank and have cycled it and have a beautiful pair of kribs that are loving their new home. Right now I have a few fake plants and a fake log but I want a better set up and I especially would like some plants and maybe some small schooling fish to add some more activity to the tank. I have no idea how to begin with live tanks. I work EMS so there are times where I'm gone 48 hours straight so I need something that is somewhat low maintenance. If you have any ideas please let me know. Thanks!
