I have a new 20 gallon high tank with three male feeder guppies, a red cherry shrimp, and live plants. One of my guppies is flashing (quickly turning to the side and sweeping across the sand). I do not have a hospital/quarantine tank to treat him in. I was thinking of buying a specimen container (the things that fish stores use to put fish in before they're put in a bag) and hang it on the side of the tank and use a bath.
What medications are available that can be used as a bath for parasites?
Because I have shrimp, live plants, and my tank is still cycling (my ammonia is 0.25 ppm) I can't add anything to the whole tank that would harm any of those.
I have aquarium salt and aquarisol on hand.
