Over the past few days, what appear to be black specks/spots have started appearing on my 7" Red Spot Severum. Not something Ive come across before, any idea? Some appear to be on the skin, others seem to be hanging off the skin, like on the mucus coat (dont know how else to explain it). Also, none on the fins, just the main body.
Tank size: 400L, full mature, 15 months, running two mature eheim filters.
Water stats: 0 Ammonia, 0 NitrIte, ph 7.4, NitrAte 20-30. Stable since set up, so not ammonia burns.
No other fish in tank affected, full stock in signature (Rio 400).
Few weeks ago, had an outbreak of ich, this cleared up, lost a couple of fish, since then all seemed normal until these black spots appeared on the Severum.
Any ideas what it is and how to treat please?
