Review: Works and is Inexpensive - They should let people know, perhaps on the front label, that this is basically Tea Tree Oil. So it's mostly a natural medication. I used it on my Betta Fish, and it healed fish of minor fin rot. The instructions are very clear; but the water does get a bit murky and icky after 3 days of treatment (halfway through). I did several small water changes to stop the water from looking icky and murky during treatment due to my smaller 5 gallon tank. But I had to do a complete tank cleaning after the 7 day treatment - cause the water is so murky. But it works, and that is what counts! I would definitely recommend
Review: Works great - Worked great. Saw an immediate change in my fish. He is up swimming and doing well. His color is much better. Whatever was bothering him is gone. I did a price comparison at a local pet store and this one was half the price.

## Questions & Answers

**Q: My betta is lethargic and hiding with some scale discoloration, will this help?**
A: There are a lot of reasons for his not feeling well, so the short answer is: It might. It seemed to soothe and help my little guy, and I don't think it hurts the fish at all; but there could be issues with the water, or he may be constipated, or have some fin rot or a bacterial infection. While the BettaFix can help in the short run, you have to find out the cause of his illness and address that. Check out bettatalk.com or bettacare101.com, they had a lot of helpful info and tips for caring for ailing bettas.

**Q: When using Bettafix do you remove the filter?**
A: This is somewhat of a science experiment, but I don't see the filter being a problem with water soluble products like Bettafix - which I purchased from my local pet store not Amazon.
I changed the filter completely and downgraded to a smaller BioBag filter pack than the one specified for the tank.  However the filter is completely submerged in the water in the 1 gallon tank after a deep clean and a good saturation of Bettafix over the course of several days.  I also added two drops per day via pipette of AAA Tea Tree Oil from Australia which is the same variety of tea tree oil that the active ingredient "Melaleuca alternifolia" or "Melaleuca" in Bettafix.

After about a week the fin rot has definitely improved and the fish - "Danny Ocean" is a lot more active.  

Another factor was the 50 Watt heater I purchased for his (1) one gallon tank.  It does keep the temperature at approximately 90 degrees verses 78, but the cold office temperature is probably what got them sick in the first place. 

After a week, I haven't seen any repair, but the fish certainly seems to be more active.  Hope this helps.

**Q: Can I use this with snails in the tank? Also does this work for velvet?**
A: I use this in my tank with a betta, snails, bristle nose plecos, and black kuhli loaches with no issues. This product is more for bacterial infections. Velvet is a parasite, find Erythromycin for parasites.

**Q: Will this still work for abrasions if my filter is running?**
A: I am not an authority on this, but I believe this product will work even with a filter running. It is a liquid that dissolves into the water and is probably smaller particles than your filter.

### ⭐⭐⭐⭐⭐ Works great against fin rot
*by L***5 on July 17, 2013*

My betta fish didn't look great when I got him, but he was a color match for one I'd bought with my nieces and nephew that didn't make it through his first water change. I was careful, but the other guy just didn't handle the stress of the new tank. I've had many betta fish over the years. They normally last about 6/7 years. I hadn't had one in a while and I felt it would be a fun thing to get for the kids. So, when the little guy didn't make it I rushed out to the pet store looking for a near match so the kids weren't upset. The only similar fish the pet store had looked a little tired with fins that weren't great, but not that bad. I took a chance and thought he might do better with a good water change, nice size tank, and some TLC. I used a little aquarium salt at first as I'd read it fixes most issues like these, but it wasn't enough. His energy was good, but his fins got worse, and clean water changes weren't working. I think they were stressing him out. It didn't look like normal fin rot. The tail had gotten really pointy and strange looking. I've never had that happen with a fish before. In fact, I've never had to deal with fin rot at all. After some research I bought this to give it a shot and within a week the little guy has a nice, normal, fan-like tail instead of the pointy rotten one. He's doing great. I've never used a product like this, so I have nothing to compare it to. I didn't know what to expect, but I'm thrilled with the results. The little guy is flaring again and swimming all over the tank. I'll keep this product on hand as long as I own fish to ensure I have it if they need it. I think when using this product, like with any chemicals for your fish, that you follow directions and err on the side of caution so as not to use too much. My little guy is recovering and I've stopped using the product. There's a very small hole in the tail, but I think at this point the aquarium salt and frequent clean water will heal that.
