Fallow tank help.

[ZachariahBeanzz]

Hey there, so recently my 20g tank caught some parasite. I added a RG and whatever jt was killed the RG and the singular clownfish I had in the tank. I’m guessing it was flukes, velvet or brookenella. The symptoms were white grains/specs over the fish, a lot of mucus, to the point of it completely covered the clownfishes eye, fin and gill rot, they wouldn’t eat, and were lethargic. I know fallow periods depend on which parasite it was, so can anyone identify for me the parasite, and how long I have to wait before adding another fish? Also, would I be able to add coral during the fallow period?

Coral is fine.
As far as what parasite it was, we don’t know. We could guess… but…
To be safe I would do the max suggested for what things you thing it was.
