today, my mumps leather fell over, is there any specific light/ current requirement for them?

thanks,
russell

Is it sort of 'slumped' over? If so, then it is stressed from something. First, test any parameters you can. Most prefer a moderate to moderately high flow (facilitates shedding) and moderate to reasonably high light. If it doesn't get better afterwards, then I would do a large water change and check for any parasites.
