Umm.. Some of the fish used to a little.. but the turtles are the rulers of the tank and they have eaten enough of the fish taht the fis hhave learned to leave them alone.. my female turtle "Getrude" DOES have a friend though.. my Pleco.. It is pretty big.. And helps her groom her shell.. She also shares her food with it. She is the ONLY fish she deosnt; try to take a bite out of while she is eating.. Spanky tolerates it as well.. As far as the rest of the time.. the turtles and fish get along jsut fine... as long as it is not feeding time. . Iahve Cichlids, an Oscar, various tetra's, louches, goldfish, and fresh water lobsters. And yes, if you look at my tank poics.. at the very top of the tano you will notice what appears to be a slight yellow ramp.. That is a floating island baskign area for the turtle.. my next project is to build a terrarium on top of the tank... where the turtles will climb the ramp upto the very top and have a grass area.. that is a ways off though.. and they are hapyp with how they are. The tank loosk very cool with ym 2 painted turtles wimmign around... If you do it though.. make sure you have adiquate filtration.. I currently use bot ha Whisper 330 and a nice undergravel fitler systen with 2 power heads.. doea GREAT jon.. although i woudl liek to upgrade the whisper 330 to a canister filter... oh well.. the upgrades are never done!
