Identify sickness?

[bakamate]

I am having her since October. In the past few days she lost her appetite and floats up for air more frequently. Today I've noticed this small white thing hanging out of her cloaca. In the past few days the temperature of her tank was a bit warm (around 23 celsius), but I will transfer it to a less warm place this weekend.
