I have a 10 gal tank that contains native (iowa) inverts including planaria, leeches (no idea on the species), water boatmans, insect nymphs (don't know the species), common ramshorn and trapdoor snails, diving beetles and many smaller inverts. Also have flathead minnows and ghost shrimp. I was wondering if anyone has experience with insects planaria and leeches. I have had the leeches for 4 months and am amazed they are still alive. i know boatmans and diving beetles usually mate in flight but can they mate on top of the tank?
