frozen vs dry pellet food

[o.c.d.]

For fish to not get sick. Just like how we can treat them for some disease with a copper treatment. If you make them ingest it , it will be less likely for them to get sick. That is what I was told. I'm sure many people with reefs use it and have unexplained coral death or can't keep certain coral, this may be a contributing factor after all any reefer will tell you copper and coral don't mix well.
