Hello, all. I certainly need some help and advice about the best setup tips I could apply to my RES. The story of acquisition is an odd one.
In 2005, my then-fiance's dad remarried. His dad and step-mom returned home from their honeymoon in Daytona Beach and brought him a little souvenir: a RES. We had no idea what kind of turtle it was or even how to care for one. I took it to the local pet shop and asked how to care for it. I was told to buy a dock, get a 10 gallon aquarium, fill it halfway, and be on my way. I already had a 10 gal. aquarium kit from my fish-having days, so that's what I used. The RES lived quite happily in that little tank for over 3 years.
The guy and I split in 2006 and as I was moving my belongings out of the house, he told me that he was just going to take the RES out and set it loose in the creekbed by the house. I was afraid for the poor RES and so I just took him with me (me being the bleeding-heart animal lover that I am). I kept him in the 10 gal. tank that I had, like I said, up till about a month ago. He had gotten so big that there was just no way I thought he was comfortable. However, I live in a small apartment and am on a squeaky budget. That being said, I had my sister pick up a 20 gallon long tank from Petsmart. I really don't have room for it, but I'm making do.
I didn't realize how much work a RES required. I had no idea of the cost, the lifespan, and all the care that was needed. I never asked for it, but neither did this little guy, so I want to give him the best life I can.
I know that I've read the tank requirements here and certainly, he should be housed in a much larger tank. But there's no way I can do it...not now, anyway. He's got a great deal of room in the 20L and seems very happy. My question is, how can I make it better within my means?
As of now, he's got a dock, a filter, a heater (all left over from my fish-housing), a lamp and the occasional calcium tablet. The water level is nearly half full, and he swims all day. I've read about the addition of plants and the lovely rock sculptures that some of you have.
I know I got a bit windy, but I'm very open to suggestions and eagerly looking forward to them! Any advice you guys can give would be much appreciated.
