Antibiotic I: Designed to primarily stop infections from gram-negative bacteria. We use our Freshwater Fish Flake Food for the base formula on this flake. It has added garlic.  Feed this medicated fish food exclusively for 10 days.

Active ingredient: Kana mycin Sulfate. Now contains beta glucan. It is water-soluble, so the Proper Feeding of Medi-cated Fish Food is a must-read. We recommend feeding our Prevent & Recover Fish Flake for 1 week after the medicated feeding is discontinued. For ornamental fish use only.

Antibiotic II: To compliment our other antibiotic flake, this one attacks gram-positive bacteria. Since your nitrifying bacteria are also gram-positive, using medicated fish flake food is by far the best way to combat this type of bacteria. Feed this fish food exclusively for 10 days.

Active ingredient: Oxy tetracycline Hydro chloride. Also with beta glucan for immune boosting. This is water-soluble, so the Proper Feeding of Medicated Fish Food is a must (See Article section of Tabs).  We recommend feeding our Prevent & Recover Flake for 1 week after the medicated feeding is discontinued. For ornamental fish use only.

Packed in a Black Foil zip-lock bag, which will keep your food fresher for a longer time.

Antibiotic one flake two betta thumbs up

The red antibiotic flake was liked immediately by both of my sick bettas one with dropsy, . The metroplex antiprotozoan one they didn't like but would take a bite if I soaked the flake first in seachem garlic guard.

Very helpful in treating white spot / injury on my Chocolate Gourami

I purchased both gram-negative and gram-positive flake foods even though I planned on only using the gram-negative one just in case I needed it later. Some of my Glofish Tetras have been bloated for quite a while (over a month), but not pineconing and acting completely normal so I wasn't sure if this was dropsy or not. I also noticed one of my Chocolate Gourami's had a wound or white spot just adjacent to its eye about 0.33 cm wide in diameter and was starting to get slightly larger each day. I used the gram-negative flake food and within 3 days I noticed the white spot was diminishing by 25%. By the end of the 10th day it was completely healed. Chocolate Gouramis are very rare and sensitive to water quality (I do 50% water changes/week) so I am very pleased with this outcome. My Glofish Tetras are still bloated, but act completely normal still and I am starting to think it was just because they are female and gravid or just overweight since they always quickly get to the food first before everyone else. The other male Glofish are not this way. My Angelfish, Samurai Gourami and other fish also had no issues and all loved the food. It was pretty easy to feed them this food. I have recently purchased the recovery food as well. It is coming today and I will start feeding them that tomorrow.

So far so good!

This is the only thing that has worked so far to treat a slow moving columnaris outbreak (from new guppies). I ordered the red and orange flake to use and treat at the same time. I’ve tried everything from Kanaplex with Furan 2 to straight powered Oxytetracycline. Nothing worked until I ordered this food! It’s a must buy! Thank you so much!

large koi in outdoor pond

A month ago I had my pond completely redone. My koi were put in an irrigated tank for most of the day which was very stressful for them. I noticed several of my large koi starting to develop some pinkish skin areas, probably wounds, so I had to do something fast so they wouldn't get infected. Found this food and purchased both the orange and the red and fed in equal amounts. The fish are looking and doing much better. The flakes are huge so it was great for my large koi.

Seems to be working

Fish seem to be doing better with the medicated food. Thanks, Angels Plus.
