Thanks, I'll try and put more water in or maybe upgrade my tank then!
I've been trying to get her to eat the earthworms recently but she just doesn't seem interested anymore :\
As for checking the water I do use a API test to check the water after a few hours once its been changed. It normally comes up perfect regarding nitrates, ph, Gh but the KH can be a tad low sometimes. I always make sure to filter the gravel and remove any dead food and poo from the water and their toys.
As for her little escape it was due to a tiny hole where the wires of my tank heater are at the back. It was probably just after I had fallen asleep so she was probably out for 8 hours. Waking up I had noticed she was gone and found her at the back of my bed shrivelled up looking dead. She hadn't gone hard yet so I got a clean cotton bud and wiped gently off all the dust around her and dipped her back in her tank and let her rest on her log. She revived within an hour but didn't move for quite a while. I had noticed her leg looked a little damaged as she was lying on top of it but then started moving normally the next day. A week and a few days later her arm was yellow and swollen and now she is in this state
I will try to get her to eat the earth worms again and see if i can do anything about raising the water level!
