i had a pair for half year now, until 5 days ago. I noticed the male stopped eating and started with a small grey on the upper lip. Now the whole mouth is grey and opened all the time. No luck with feeding. Anybody know what this is?
The only time I notice what you mention is when my fish lip lock, its possible yours have been lip locking and his jaw has been dislocated perhaps, but probably quite unlikely...probably some kind of infection
