Seachem focus reef and inverts safe ?

Thanks for the info.
Just have to ask these questions cuz someone saying they feed a lot could mean a lot of different things to dofferent people.

But having another large tang is a good gauge for comparison.

I know it doesn't really help, but from your info, for sure I would try and treat the Naso. Definitely sounds like something is off with it.
