Non 3d black spots and other spots powder

[Oaken]

Noticed these spots a few days after I got this powder brown. Tank is 5 montha old no coral. All fish came from a very extensive quarantine process done by a qt vendor near me in houston.

Ive never seen him scratch or anything but the spots seem to gain a few each week but not many and now I see a weird white hole type spot near his tail on one side.

None of the spots are raised, as in how ich would be a polyp type disease or parasite. They appear to be sub-epidermal

Looks like what is known as black ich which in essence is not the parasite ich but rather turibella n worms
A freshwater dip will pause them followed by treatment in a quarantine setting using prazi pro for an 8 day interval follies by water change and one more treatment for 8 day period
Maintain and monitor good water quality and increase oxygen as praziquantel reduces both appetite and oxygen

Sorry, I can’t see the white spot near the tail.

The black spots are most likely a cyst of a turbellarian worm or a digenean trematode (much rarer). In common parlance they call this “black ich”. There are at least two species of worm in play.

I’ve found this to be self limiting in some cases - it just goes away. In other cases it gets worse and needs to be treated with formalin dips.

People will suggest praziquantel but that doesn’t really work on turbellarians, and the mechanism it works through is it causes the fluke to let go - since these are sub dermal, that doesn’t work.

Thank you for your response. If I dip them won't the worms still produce in the sand bed?

Thank you. I'll look into prazi pro. I don't have any coral but I do have invertebrates

Depends on the actual species involved here. Some people also siphon off their substrate to help reduce reinfection.
