They did say to bind it to food pellets with focus so I would not be just treating the water.
I just don’t know what to do.
Should I try both at the same time- the ruby rally and the metroplex bound to food?
Unfortunately, Metroplex 'bound to Focus' doesn't prevent the Metro from getting into the system. Besides this, getting the
exact correct dose is hit-or-miss. I've found the use of
Medicated Flake Food to be slightly better than the Focus process. But, I'm not sure this is needed, since I can't make a good evaluation from the photo (see below).
Help the fish by improving its immunity and ability to heal wounds by adding supplements for an ill fish to its diet as recommended in the
Fish Nutrition document. Click on that link, then download (and read) the document. Use especially Beta-1,3/1,6-D-Glucan found online, in health-food stores, and pharmacies.
Lastly, I can't provide a good evaluation/diagnosis from the photo you provided. A
video longer than one minute under white light up close to the fish, showing both sides of the fish would be helpful. You can upload the video to YouTube then post the link to it here.
