I have 3 turtles(2 sliders and a juv map) and 2 tiger oscars in a 240gal. I have 2 FX5's stuffed w/ specific media and nitrates are still a struggle. I'm not having huge issues w/ ammonia as predicted, but my media is specifically chosen. I was having an issue w/ my turtles attacking my oscars, but they learned to defend themselves and now they watch one another's back so all's well now. But it was touch and go for a little while, and I'm sure, for other people it often ends up bad for the fish. Anyways... I wouldn't suggest a stinkpot because they stay too small, and they are very shy, so the oscar will probably pick on it, and they like pretty shallow water. Sliders do cause trouble but I disagree w/ Jamo3030 and think a map turtle would be an acceptable tank mate. Males stay pretty small(5in or so), and though some of them do like fish. In my experince, it's the sliders not the maps to watch out for. But, i warn you. To keep a turtle is no easy undertaking. They need to have a basking platform. Most WILL get sick with out one. There are some turtles that won't but most need one. It takes up tank space and puts more on your power bill w/ the light that they'll need to have. You'll need extra filtration, extra circulation, AND clean the tank often. Finally, you have to make sure EVERYTHING is turtle proofed. As arraigning, you gotta keep in mind they can drown, and if they can destroy it, they WILL. Cords need to be kept out of the way or they will get bitten, don't bother w/ suction cups, they will soon be useless, and again, make sure everything is 100% safe. If there's any doubt, fix it. Don't forget turtle pellets. I'm not trying to discourage you. I just want to make sure you know it's not just something you plop in and leave it alone. I've adopted 2 of my turtles because people believed that, then were going to release them because it got to much. Well, good luck, and hope everything goes well for you and ur pets, do lots of research! Here's some info on the pink bellied side-necks, it says they're mostly carnivores, so be careful: http://www.hahareptiles.com/Merchan...re_Code=haha&Product_Code=PBS&Category_Code=T . BTW all turtles are sexed the same way, exactly as described
I included a pic of my platform.
