Update:
Some fish are looking good (firefish) others like the goby and blenny are doing ok but not eating. I've offered frozen bloodworms, marine cuisine, and NLS pellets.
The remaining wrasse (melanarus) looks much better than 48 hours ago but is still breathing hard despite the air stone.
I mistakenly added APIs Pimafix due to a communication error with the LFS. I hope this won't cause problems.
I cannot easily locate Kanaplex or Metroplex but will continue to try. I am continuing the Furan 2 doses and 25% w/c
