Today we are highlighting a few new fish antibiotics.  Previously Thomas Labs only manufactured fish antibiotics in capsule or tablet forms, however, they recently started making Fish Antibiotic Powders.  These powders are pharmaceutical grade fish antibiotics that are packaged in containers with a shaker and scoop lid.  You can either scoop the correct dosage or sprinkle it into your fish tank.

Fish Mycin Forte Powder – Erythromycin 500 mg

Fish Zole Forte Powder – Metronidazole 500 mg

Fish Cycline Forte Powder – Tetracycline 500 mg

Fish Bendazole Forte Powder – Fenbendazole 500 mg

Today we’re publishing a new video about Fish Mox.  This video shows the three different sizes of Fish Mox – Amoxicillin 250 mg and the capsules of each.  Fish Mox comes in 30, 60, and 100 count bottles and is made by Thomas Labs.  It is pharmaceutical grade fish antibiotics.  This video shows that the writing on the fish mox pill says “westward 938.”  The Fish Mox capsule is yellow and brown and is a gel capsule that dissolves in water.

When you use it in your fish tank it might discolor the water, which is harmless and can be fixed by performing a partial water change in your fish tank.

I know a lot of people who have purchased fish antibiotics in the past on Amazon.  Recently (within the last week) Amazon has taken all of the fish antibiotics off of their website.  I’m not quite sure why since you don’t need a prescription to buy fish medicine, but fish antibiotics specifically earned a place in Amazon’s “unallowed products.”  So it doesn’t look like Amazon will be selling them any time in the future either.  Amazon was a great place for fish antibiotics because the prices were good, and you could get free shipping too.

We have recently spent quite a bit of time searching for different online stores that offer fish antibiotics and medicines and we still didn’t find one that we like better than the store we have used and recommended for a long time.

FishMoxFishFlex.com - online store for Fish Mox and Fish Antibiotics

Why We Like FishMoxFishFlex -

Besides the fact that the products are in their name, and the name is hard to say:) they have free shipping on every order, free same day shipping (before 2pm), they’ll price match, and they have a lot of experience with the medicines.

All of that is nice, its always nice to save a few bucks on shipping, but one of the reasons I like them best is that they get new shipments of medicine 1-2 times per week. That means the medicines they carry are constantly being refreshed so the medicine you buy has the latest expiration date possible.  You and I both know that the longer something will last, the better, especially when it is for something as important as fish medicine.  You know you won’t use more than a few pills to treat your fish, and nobody wants to spend $30 on medicine, use a few pills and then save it in your cupboard and pull it out a few months later to use it again to find out that it has expired.

Thomas Labs or Thomas Laboratories is the company that manufacturers a majority of the Over the counter fish antibiotics like Fish Mox & Fish Pen.  They have been in business since 1978 and have been pharmacist owned and operated since then.  They are located in Arizona and in addition to fish antibiotics they have dozens of other products like diatomaceous earth or other pet care supplements and medications.
