Aquarium fish disease treatment.

With Tetra's Lifeguard, there is no need for time-consuming guesswork when it comes to treating your freshwater fish. A unique, broad spectrum, non-antibiotic agent, Lifeguard treats the clinical signs of disease at their earliest stages in freshwater fish. Added to aquarium water, the powerful oxidizing action of HaloShield® attacks and destroys microorganisms that can cause disease in fish.
Use for treating fungus, ick, red streaks, milky or shedding slime, flukes, bacterial gill disease, mouth and fin rot, clamped or torn fins, and ulcers. Lifeguard may also be used as a preventive when adding new fish. Five day treatment.
Lifeguard is rated 4.4 out of 5 by 6.
Rated 1 out of 5 by from Finrot got worse I bought this about a week ago due to my corydora showing signs of finrot on her back. After carefully following the dosage and even getting her her own tank (I own a 5 gallon aquarium with other fish), she has gotten progressively worse and is now dying. The finrot not only spread but she is currently bleeding out in a small bowl (i couldn't stand to see her floating around in agony in a large space). The finrot spread on her back and onto her belly- which wasnt there before. I do not reccomend this product at all (Photos attached). I'm so lucky this did not spread to my other fish.

Rated 5 out of 5 by from Works Wonders My 10 gallon aquarium has had fish dying for months. Advice was given from on line sites, pet shop owners, "fish experts". Their instructions were followed exactly and the fish continued to die. The tank had two rounds of erythromycin, two rounds of doxycycline, and copper treatments. The fish continued to die. Then I stumbled on to Lifeguard at a Petco. It was almost miraculous! After two treatments, what few fish that were left, stopped flashing and started eating. I highly recommend Lifeguard.

Rated 5 out of 5 by from My betta, Prince, is happily recovering! When I first read reviews of this product, it seemed as if this stuff was useless to use as treatment for my betta fish, Prince ,who came down with velvet. It turns out that after the five day treatment, along with the use of aquarium salt and a complete tank blackout, my betta fish Prince regained his vibrant color and peppy personality. I highly recommend using this product. But just keep in mind, the moment you notice symptoms in your fish, treat it in a timely matter. It doesn't take very long for a disease to worsen. Follow these steps and you will be on the right track to keeping your fish happy and healthy. Don't forget that results may vary ;)

Rated 5 out of 5 by from Saved My Bettas Life! On Wednesday morning I noticed that my Betta was covered in fungus and his eye was very strange looking. I bought the meds and at like 9pm I used half a tablet (2.5 gallon tank) to treat his tank. By the next afternoon I could tell he was getting better. And by this morning he is doing very well. I have only used 2 doses so far! :)

Rated 5 out of 5 by from Great product, worked like a charm! Ok, so the key to this treatment is definitely get it going early. I had a black moor starting to get covered in white spots from ick and totally lethargic and began the treatment, by the morning of day 3, the spots were disappearing and my fish was VERY active! I was sooo excited to see the black moor doing so well, especially since it was my 6 year old son's favorite fish, that i HAD to write a review. This product worked great for me for ick, but it definitely, in my opinion, depends on how early you get it going, i had a 2nd goldfish quarantined with ick, much further along that did NOT make it, but his ick was SO much more progressed. However, ALL the fish in my big tank where i did the treatment pulled through great, composed of fancy goldfish and baby guppies! Thanks Tetra!

Black molly popping long white strands, seems lethargic.  Could this medicine help?  And is it safe for Amano shrimp?

Asked by: Drumsc02
If by "popping long white strands" you meant pooping them, this is not a problem. Long white strands are simply urea. Clear would indicate parasites. Mollies require warm water, around 80 degrees, and a high pH of 7.5-8.5. They also like very hard water so an alkalinity of 120-160 ppm is recommended. And last, but not least, they are vegetarians for all intents and purposes, and have to have lots of vegetable matter in their diets. This can be in the form of Tetra Veggie Flakes or supplementing a tropical diet for omnivores with fresh spinach or romaine lettuce. BREX

Is this medication safe for aquarium snails?

Asked by: Brynn
Thank you for your interest in this Tetra product, Brynn! No, it is not safe for snails. In general, medications tend to not be safe for them ever, so it is best to remove them from a tank during any treatment. BREX

Angelfish breathing heavy, mouth protruding, lethargic, won't eat. Linger for weeks, then die. Bacterial gill disease? First time using Lifeguard, on 4th day, no improvement. What now?

Asked by: CharlesS
Well, we cannot diagnose since we are not veterinarians, but it sounds more like water quality and/or parasites/protozoa. 30% water change add two tablespoons of aquarium salt per ten gallons of water, and treat with Parasite Guard. LifeGuard should have shown improvement by now, if it was the medication needed for the job. BREX

is lifeguard safe for mystery//apple snails?

Asked by: elissap1
Unfortunately, no, it is not. Algaecides, water clarifiers, medications are all unsafe for snails, unless they are all natural herbal remedies; some of those are okay. Lifeguard is not one of them.BREX

Can it be mixed with Melafix?? 

Asked by: esmeralda7
Thank you for your interest in this Tetra product! We do not recommend mixing ANY medications unless they are from the same manufacturer, and said manufacturer says they can be mixed, so no, we would not recommend mixing these two. In fact, LifeGuard is one medication that we make that we do not recommend mixing with any other chemical at all, besides AquaSafe Plus.BREX

Will Tetra Lifeguard affect nitrification or harm the beneficial bacteria in any way?

Asked by: CharlesS
Thank you for your interest in this Tetra product! All medications can harm the biological filter to some degree or other. Typically, it will not cause any issues, unless the tank is already unbalanced for some reason, such as a lack of partial water changes. We always recommend adding Tetra SafeStart Plus after dosing a tank with any type of medication to help boost the biological filter.BREX

The colour of my fish becomes fade . Tail becomes deteriorate. What I do??

Asked by: Sagnik Chakraborty
The first thing to do is a partial water change of 30%. If the fish do not improve, then treat the tank with LifeGuard for 5 days. Do small, partial water changes prior to each dose. BREX

Can i put lifeguard with tetra fungus guard at the same time??

Asked by: Gallon5
Thank you for your interest in Tetra products! No, do not mix these two medications. Try one of them first, depending on what the fish's symptoms are, then do a partial water change and run fresh carbon for about 12 hours after you are finished with the first medication, before starting the second one.BREX
