Quite suddenly my white (not albino) axie is sick. Woke up this morning to two gaps in the tail and fin which appear shrunken rather than bitten; one eye that's turned white and a gaping cloaca(??) with white cottony stuff hanging out. There are a couple of pin-prick sized black dots amongst the cottony stuff. Roxy won't take food but is swimming OK. Strangely enough he/she (how do you tell?-am new to this) keeps swimming towards the filter outflow. Pet shop advised salt bath, which I did and the colour seemed to improve. Have isolated Roxy but have no filter for isolation tank. Is that OK?
