Hi all,

My new hillstream has a weird patch on the front of his lip, any ideas what is it? Anything to worry about? I thought it was food but it's not coming off him when hes moving

Sorry the pics are bad, hard to get a good one in a glass bowl ‍


Edit to include a slightly better photo

You have a Hillstream loach in a glass bowl? They live in rivers and need high oxygen provided by high water flow. Bad Things™ happen with them and low O2. Just checking.

Some of my fish have had similar marks when the water isn't quite what they like and/or giving birth. In this case it was and endler with pH around 6.8, raised to 7.2, she gave birth and the mark went away after.
Can you tell us more about your fish / water etc like in the emergency form?
