Thank you Serendipity.
I did think it was a bit unusal for a russian dwarf to live over 2 years myself.
She seemed to crave a cuddle from me before she went though, which was unusual as she wasn't keen on coming out of her tank. It was like she wanted me to be there with her, which was lovely, but also bittersweet as she passed away.
I am definitely thinking of getting another little russian dwarf later this year, but want to save up for a brand new wheel, den and platform as they've all had a lot of use
