I can't begin to thank you all for all the help you've given me. I am so glad I found this site.
I promised an update on Squirt so...here it is:
Squirt (as you may remember) was suffering from a type of shell rot due to poor nutrition. He had a follow-up visit last week with the rep vet and we got good news! Squirt is improving! The bad part of his shell is finally coming off and there's a small patch on his shell that is a beautiful brown (normal) color. The vet wants us to continue to shampoo his shell for the next few months but, hopefully, he will look like a normal turtle by Christmas.
Squirts nutrition has gotten much better. He still eats turtle pellets but, also eats (store-bought) bait worms, frozen squid, brine, and lots of other stuff. We just discovered that he loves cooked beef! He still won't eat any fruit or vegetables but, I continue to offer them. We put ten feeder fish in the tank just to see what would happen and got such a laugh out of it. Squirt had never seen fish before and didn't know he could eat them. It took him almost a week before he ate two. The others are all still there. He has mastered the ability to beg me for food whenever I walk by his tank. Who knew that turtles could give you the sad-starving look. Squirt has figured out that look and does it very well!
As far as the tank is concerned...we still have the rocks in it. We have sand to put down but, were warned that if Squirt kicked the sand into the filter, goodbye filter. We've resolved to more frequent water changes and the water quality is beautiful. Because we have a submersible filter that blows the water, the tank always looks like the bottom of the ocean. Its so peaceful to sit across from Squirt and watch him discover new things in his tank. Now that Squirt has the size tank he needs, he is swimming and fish hunting often, which gets him basking as long as he needs. I can't believe that I've fallen for this little turtle but, I have!
One last note: I have GREAT news!!!
I just got the news today! Squirt is now an official member of our family! My daughters school has decided to relinquish him to us! We are so excited! Squirts life is looking up for sure!
