Ok sorry have to be honest here I keep a lot of pets and I keep them well, but my experience with the soft shells was bad. I learned the bad way and we had losses but I will share that with you in an effort to help you. I had two of the little buggers. Cute as all get out. I loved them. I used too hard a substrate (if only this forum had existed then) and they like to dig and sit under the substrate and it scratched their shells leaving a place for fungus to harbour and I lost one that way. Both of the softshells had become infected with the fungus but I treated them with Melafix and was able to save one of them. Unfortunately, and I'm not quite sure how this happened but I had put in a flower pot for them to crawl up on and bask and it absolutely was sitting on the bottom, not on the sand but somehow the one remaining turtle got inside under the flower pot and drowned. I am still scarred from the experience. I kid you not. I still cringe when I think about him drowning. But it taught me that baby turtles are like that and that also holds true to the hard shelled varieties. Babies often get stuck, so you have to make sure the tank is baby safe. I did with my other turtles and I now have complete success. Chalk it up to unfortunate misfortunes, but I suppose everyone has a failure now and again and you just need to move on. Anyway they do seem to get slightly more intelligent as they age. Good luck. If you go ahead and get one of them I hope you are 100% more successful than I was.
