API BETTAFIX Antibacterial & Antifungal Betta Fish Infection and Fungus Remedy 1.7-Ounce Bottle

Works like a charm!!!
This stuff is like magic.. my sons betta was not doing well and had damaged his fins on the tank decor. (now removed) Used this everyday as it said to and his fins are healing and looking even more colorful within 3-4 days.

So Far, So Good
Using for the last 4 days, my Betta tears his fins a lot, trying to fit in places he can’t. No negative side effects so far, he’s perked up, though this could be because I moved him to a separate tank (no snails, just him and his hides and some plants).
I’m confused by all the 1 star reviews claiming this killed their fish (and frogs??? THIS ISN’T FOR FROGS! It’s irresponsible to use it on frogs and then blame the product when they die. C’mon.) I see a lot of reviews stating “My Betta was healthy and happy, and then I used this for 2 weeks and it died!” Well first of all, this is for fish that are suffering fin rot or bacterial infections. If your fish doesn’t have either of these, probably shouldn’t be using it! Secondly, the instructions say 7 days and that it CAN be extended, but not to over use it. TWO WEEKS seems pretty extreme. If after a week you don’t see improvement, why continue to use the product?
Anyways, Hewey is doing fine and seems healthy, happy and readily eating (he’s pretty picky). Will probably keep a bottle or 2 of this around for future use. But once his 7 days are up, will stop using and if still having issues switch to Seachem Paraguard or StressGuard as I’ve had success with them in the past for things like fin rot.

Good product, but worse cup design
Good product for your Berta fish, but I had received a item that different from the picture. This cup design makes it hard to add the right amount of the medication for my betta.

Danger, Will Robinson!!!
1) this “heals” (I think) by irritating your fish until it produces a better slime coat 2) it IS an antibacterial/antimicrobial/antifungal for the water so if your water is scummy or full of algae, it will clear it up in 2 days. It will also kill your plants because it messes up the water balance. 3) if your Betta is on death’s doorstep, do NOT use this. If you try it, do about 10% for 2 days to see how he tolerates it. The weaker the fish, the more likely this will kill him instead of helping 4) make D**NED sure you’re water balance is PERFECT before adding 5) be aware that this will send your KH and TAL through the roof and mess with your pH, even in a perfect tank. MONITOR CLOSELY.
I can’t say never to use this. It really did clear up the bacterial biofilm on the surface of my tank for a while BUT I only used full dose on the 3rd day. Water parameters went psycho, after that. Betta quit eating… I hope he survives.
I recommend finding a good Betta forum online before getting to desperate place. I believe that most Betta illnesses are a result of malnutrition, now. Ignore the employee at the Big Box store who says to give them one lekker every other day and feed them according to the directions on their food. Big Box starves them so the water in those cups doesn’t get too dirty.
I’ve lost 3 bettas that I think the cause was starvation or malnutrition from following Big Box advice (and waiting until they were nearly don’t to try bettafix, as stated, they were too weak for it to do anything but stress them the rest of the way). I kept treating the symptoms in desperation, not knowing the cause.
But seriously. Monitor CLOSELY if you try it. Start low dose. It has some benefits but don’t use it to try to “save” a sick fish.

I was really happy with that

Tengo que probarlo
