Marine ich velvet or brooklynella

[dabgod43]

I’m new to saltwater I have a mixed reef tank. A few weeks ago my fish started getting these white spots wasn’t sure if it was marine ich, velvet or brooklynella. Every fish I had showed symptoms at night and was gone by the morning. Only survivor is my yellow watchman goby. Besides the fish shown I also lost 3 clowns, a firefish, green mandarin, blue yellowtail damsel. Please help determine what this is

Welcome to Reef2Reef!

That is marine ich, Cryptocaryon.

Treating it once it has begun to kill fish can be difficult, because that means that the infection is very far along.

The two treatment options are coppersafe or low salinity. Neither of those can be done in tanks with invertebrates or corals though.

I can walk you through the treatments, but you’re going to need to act fast!

This is ich and you will need to place fish in Quarantine tank and treat with Coppersafe or Copper Power at therapeutic level 2.25 for a FULL 30 days (do not interrupt this 30 day period) monitored with a Hanna Brand copper test kit- No API brand. Also monitor Ammonia levels while in quarantine with a reliable test kit and add aeration during treatment using an air stone. All other fish in with it should also be removed as they have also been exposed to the parasites and placed in quarantine tank.
The display tank will have to be kept fishless (FALLOW) for 6-8 weeks to assure the existing parasites go through their life cycle without a host fish and die off. Inverts and coral can remain in the display (not treatment) tank during fallow period.
A quarantine tank can be as simple as a tank from a second hand store, a Rubbermaid type tub or a starter kit from Walmart which most of the needed essentials.
