My yellow box fish is acting very strange today... He is lingering at the top and bottom of the tank when he is usually always swimming around. If he were any other fish I would not be concerned, but I understand he will emit a toxin that will kill all of my other fish when he dies or is close to death. Does anyone know how I can distinguish between a yellow box fish on its way out vs a yellow box fish having an "off" day?
keep activated carbon in your system at all times as a precaution, also, when you say yellow boxfish are you referring to a yellow cubicus or a cowfish? It would also be a good idea to set up a quaruntine tank for him incase treatment is necessary, (assuming you already have one), i've seen ostracitoxin wipe out a tank before, it's never a pretty site
