ParaGuard employs a proprietary, synergistic blend of aldehydes, malachite green, and fish protective polymers that effectively and efficiently eradicates many ectoparasites on fish (e.g. ich, etc.) and external fungal/bacterial/viral lesions (e.g., fin rot). It is particularly useful in hospital and receiving tanks for new fish and whenever new fish are introduced to a community tank. For use in freshwater or marine. ParaGuard is recommended for the treatment of certain diseases in marine and freshwater fish only. It IS NOT recommended for treating any style aquarium containing invertebrates, corals, crustaceans, or elasmobranchs (sharks and rays). ## Features - Fresh Or Saltwater Use - Parasite Control - Great in hospital and receiving tanks ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000255R3I | | ASIN | B000255R3I | | Allergen Information | Yam Free | | Best Sellers Rank | #28,435 in Pet Supplies ( See Top 100 in Pet Supplies ) #252 in Aquarium Water Treatments | | Brand Name | Seachem | | Customer Reviews | 4.6 4.6 out of 5 stars (1,697) | | Date First Available | June 20, 2004 | | Global Trade Identification Number | 00000116060509 | | Included Components | Seachem ParaGuard 100ml | | Item Form | Liquid | | Item Type Name | Medication | | Item Weight | 4.2 ounces | | Item model number | 001273 | | Liquid Volume | 100 ml | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 605 | | Model Number | 001273 | | Pet Type | Fish | | Product Dimensions | 0.16 x 1.61 x 0.16 inches; 4.2 ounces | | Target Species | Fish | | UPC | 015568977237 000116060509 | | Unit Count | 3.4 Fluid Ounces | ## Product Details - **Brand:** Seachem - **Item Form:** Liquid - **Item Weight:** 4.2 ounces - **Liquid Volume:** 100 ml - **Number of Packs:** 1 ## Images ![for external fungal/bacterial/viral lesions ParaGuard 100ml - Image 1](https://m.media-amazon.com/images/I/71iZ+jt9cHL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: I have 1 gallon fish tank, how do i use this product? do I need to do a water change after first dips?** A: Seachem states: For 1 hour dips, use 3 mL per 4 L (1 gallon*). Dips may be extended if fish show no evidence of stress. It says nothing about a water change. **Q: Does this kill leeches and leech eggs? Will be used in quarantine buckets for plants and decorations, not the tank.** A: Malachite green whish is active ingredient kills them so in theory yes it should work. I've used it for hdras and flukes which both tend to be more hardy than leaches. **Q: Will this cause ammonia spike? Or, kill any beneficial bacteria?** A: I personally didn't have any problems. I used a half dosage twice a day and it worked well. I would use caution though with sensitive fish. **Q: I have 37 gallon tank and how many times do i use to cure the ich?** A: I used a capful for my 37 gallon tank and followed the instructions on the bottle for the amount of daily treatments. Hope this helps. It cleared my tank of ich and will take care of any parasites. If you have shrimp. etc it might be too strong for them...I only had fish. ## Frequently Bought Together - Seachem for external fungal/bacterial/viral lesions ParaGuard 100ml - Kordon Methylene Blue Disease Preventative – Safe for Freshwater & Saltwater Aquariums, Prevents Fungal Infections & Treats Parasites, Reduces Fish Stress, 4-Ounces - API LIQUID SUPER ICK CURE Fish remedy, Freshwater and Saltwater Fish Medication 4 fl oz(Pack of 1), White --- ## 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.tn/products/12204032-for-external-fungal-bacterial-viral-lesions-paraguard-100ml](https://www.desertcart.tn/products/12204032-for-external-fungal-bacterial-viral-lesions-paraguard-100ml) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-01*
