Fritz Maracyn - for Saltwater and Freshwater gram-Positive Relief from Bacterial gil, Popeye, More - Easy dose Packets, 20 Count

Fast shipping and effective treatment when being a marine biologist isn't your forte! I have a small hobbyist type tropical fish business and when I needed 500 fish saved from an unknown biological apocalypse both Amazon on Fritz saved the day

Great value for money. This is one of my go-to medications for my tank. The fish seem healthy and the quality of the medication is sprayed. Color is consistent and as long as you don't eat it, it's safe.

My goodness, my fish had a parasite on its fins, big orange huge one. I bought this (expensive)stuff here, the next day the parasite was gone, and so was the fish floating at the top.

Quick shipping. Was able to treat my fish in 24 hrs. Bought extra to have it

My new betta had something on his eye. This not only cleared it up but I hadn't realized the discoloration on this head was something to be concerned about as it was there when we got him. He's looking so good. We only have a 3 gallon tank (I KNOW it's small it wasn't supposed to be for the betta but here we are). The online made more sense than the written instructions for smaller tanks. One thing that isn't mentioned is snails. My tank had nerite snails. I noticed at the 2 hour mark my guys were tucked in his shell and had fallen off the side. So I quickly removed them to another tank. (Thank goodness we had a second tank available). They snails are fine but I was scared.
