Black ick ?

Zatai41 · Feb 12, 2020

Hey guys

My yellow tang has black dots on his body.
I treated with GC (1st dose then 2nd dose 6days after).

He still has after 2 round of GC.
Could this be something else ?

Havnt done fresh water dip on him yet.

Thanks

GC should take care of it.

Dosing with the liquid Prazipro will give the tang a slightly higher dose of praziquantel. In Prazipro the dose is 2.5 versus the General Cure dose of 2.0. Plus the liquid Prazipro will express better in the tank water. GC 's powder sometimes has a very difficult time completely dissolving. Often you find lots of little white granules on the tank bottom of GC.
