Melafix should be fine for your other fish, but to prevent possible infection from your sickly puffer it is recommended that you quarantine him. This will also enable you to check his eating habits, faeces and behaviour.StingrayKid said:Would malafix be okay on my other puffers? And, how do I know for sure that it's parasites?
Here's a quote from http/www.theaquarians.net/ArticlesandWal...parasites_2.htm regarding parasites:
Sunken Belly—If the fish is eating and continues to lose weight, there is probably an internal parasite present, especially if the waste is stringy. If he is not eating and appears emaciated, his loss of appetite may be caused by parasites or by something else. A sunken belly may also be caused by Tuberculosis. Try to identify other symptoms. (Make sure that you are feeding the fish an appropriate diet—some of these guys are very picky)
Stringy Poop—A good sign that there is an internal parasite present is stringy, whitish poop. Normal waste should be solid looking, opaque, and a color that reflects what the fish is being fed (mostly shades of brown and green).
Once again, by quarantining him you will be able to observe whether or not he is showing these symptoms. The website I mentioned is also worth a look in case he is exhibiting any other signs of distress.
