Review: I always get nervous using medications because some can be harsh on fish and beneficial bacteria but I had no issues using this. Everyone in the tank handles it well and the sick fish bounce back faster than you would expect. I 1000% recommend it to other fish keepers who want something reliable that actually works. I like to keep this and Kanaplex ready to go so I’m prepared for any sudden issues. Review: This is the only product so far that has helped to clear up the fin rot in my community tropical fish tank. I tried several other antibiotics and antifungals and my water parameters were all perfectly fine and could not get it to go away. The medication is doxycycline which is a broad spectrum antibiotic so you have a good chance of it working against whatever bacterial agent is causing disease in your tank. I have noticed the fins of my fish already growing back and looking significantly better. The things I did not like about this product is that it severely discolors the water to the point where it looked like red wine by the last day of treatment and you can barely see through it. It said on the box that it would cause a slight discoloration of the water but I did not expect it to be so extreme. I also needed to use a net to scoop off the foam because it was very thick and frothy (think like foam on a latte but grosser and purple) several times a day. I just did my final water change and put in some activated carbon to hopefully remove the color. My tank is a 60 gallon so it also takes a lot of this product to complete the dosing (it's one packet per gallon and you treat a total of 4 times) so it's a bit pricey but I'd still say it's worth it. Otherwise, I've been battling with this fin rot for about a month now and have finally gotten it under control so I'd consider that a success even if it was kinda gross looking and a pain in the butt. ## Features - Item Category: Aquarium Pond Water Treatment - Item Trademark: API - manufacturer: API ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JJ18VZR | | Best Sellers Rank | #39,611 in Pet Supplies ( See Top 100 in Pet Supplies ) #326 in Fish Medication & Health Supplies | | Brand Name | API | | Customer Reviews | 4.5 4.5 out of 5 stars (447) | | Item Form | Powder | | Item Weight | 0.2 Pounds | | Manufacturer | API | | Manufacturer Part Number | 17P | | Model Number | 17P | | Target Species | Fish | | UPC | 317163160176 | | Unit Count | 2.00 Count | ## Product Details - **Brand:** API - **Item form:** Powder - **Item weight:** 0.2 Pounds - **Manufacturer:** API - **UPC:** 317163160176 ## Images ![API 2 Pack Fin Body Cure Freshwater Fish Powder Medication, 10-Count Per Pack - Image 1](https://m.media-amazon.com/images/I/81kLTlYvl1L.jpg) ## Questions & Answers **Q: Will this work for blue green algae?** A: No this treatment is for bacterial infections in fish **Q: Is this safe for scale less fish?** A: Yes I have used it in a tank with an Oscar and an Eclipse Catfish. The Oscar needed to be treated and it did not harm the catfish. **Q: What is the ratio for making a food out of this for goldfish in a 55 gallon tank?** A: I add it to my tank, per the directions on the package. I don’t mix it with food. I would go to the API website and ask them. **Q: how much would I use for a 3 gallon tank?** A: I would use almost1/3 of a single packet for 3 gallon tank. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***E on 4 December 2025* I always get nervous using medications because some can be harsh on fish and beneficial bacteria but I had no issues using this.

This cleared things up in several days adding to the tank. I also mixed a small amount directly into some frozen shrimp food to feed directly to some funky/sick fish and they recovered quickly. It can create some alarming looking brownish foam in your tank but wasn't detrimental ## Frequently Bought Together - API 2 Pack of Fin and Body Cure Freshwater Fish Medication Powder for Treatment of Bacterial Diseases, Treats Body Slime, Eye Cloud, Fin and Tail Rot, and Gill Disease (10-Count) (2 items) - API Powder General Cure 20 pack - API MELAFIX Freshwater Fish Bacterial Infection Remedy 16-Ounce Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/285143580-api-2-pack-fin-body-cure-freshwater-fish-powder-medication](https://www.desertcart.co.th/products/285143580-api-2-pack-fin-body-cure-freshwater-fish-powder-medication) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
