turtle+fish=fed turtle but really its your choice you have to come to a decision to call a your tank a turtle tank or a fish tank a chinese soft shell turtle isnt that a herbivore? you might want to check out www.turtletimes.com they can help you on the turt stuff.... I keep a slider with some tire tracks two senegals and various malawi cichlids and havent lost any fish for almost 2 years cept for fish that was asleep at night and I flicked on the lights and the turtle woke up and well you get the picture but my tank is a turtle tank but like many monster fish on this site they might also eat their tank mates
