thanks you have just made my desicion for meI had a snapper live with a dovii for five months before I inevitably had to take the snapper out and re home it. It tried to take a chunk out of my dovii lol its super cool when u see it but turtles are dirty believe me I know I have five I've had for 14 yrs. Lol anyways there super dirty make the water not ideal for your fish not worth it in the long run but it can be done with big enough tank just not worth it to me
