I had a red ear slider years ago and he passed away on me after keeping him for a week or two. I still do not know what I did wrong... after he died I sat on my bed crying and petting his shell and told him how sorry I was. Even though our time was short together I really enjoyed him and I know you will too. Looking at your lil guy brings back happy memories! I love your tank setup and it looks like Squirt will be swimming in a "ocean" now!
