The following fish should not have
MELAFIX used at any time for any illness as it causes an interference with the Labyrinth organ and the ability to use it.*
Perch
Combtail
Ctenopia or Ctenopoma
Betta
Gourami
Paradisefish
Pencilfish

I realize that this article deals mostly with Bettas but if you read closely you will see that it mentions that it states that Melafix affects all fish with Labyrinth organs which are the fish listed above.*
If you have any of the above fish and are treating them with Melafix please do immediate 90% water changes and use carbon to remove all traces of the medication and switch to Bettafix if the fish needs continued medication or discontinue medication or notify us and we will try to come up with a suitable replacement for you to use that will not hurt your fish.
This information was just given to me through Butterfly and we posted it as soon as we could.* I do hope no one's pet is hurt by this.
