Treating Guppies with eSHa 2000: Fixing Fin Rot & Fungus
If you keep guppies, you know that their tails are their pride and joy. But those massive, flowing fins are also magnets for trouble. One day your award-winning male looks perfect; the next, his tail looks like itâs been through a paper shredder or is covered in "cotton wool."
This is where eSHa 2000 shines. It is a broad-spectrum treatment that targets over 18 different pathogens, making it the perfect choice when you aren't 100% sure if the problem is fungal or bacterial. For guppies, it's a lifecycle-saver.
The Fin Rot Crisis
Fin rot is usually a secondary infection. It happens when a guppy is stressedâmaybe by a bully, a sharp decoration, or a dip in water quality. Once the fin is damaged, bacteria move in. If not treated, it can travel up the tail and hit the "body" (the peduncle), which is often terminal.
eSHa 2000 vs. Fin Rot
eSHa 2000 doesn't just kill the bacteria; it actually contains ingredients that help stimulate the fish's natural slime coat to repair the tissue. For guppies, youâll often see a "white edge" of new growth on the fins within 48 hours of completing treatment.
Step-by-Step Guppy Dosing Routine
Because guppies are often kept in smaller 10-20 gallon tanks, getting the drop-count right is critical. eSHa 2000 is high-concentration, so one extra drop matters.

The "Fry Check"
If your guppy tank is full of fry, you might be nervous about dosing. The good news is that eSHa 2000 is remarkably safe for baby fish. I have dosed at full strength in breeding colonies with hundreds of fry without losing a single one. Just ensure your oxygen levels are high.
Water Prep
Guppies love "harder" water (higher GH/KH). eSHa 2000 is more stable in hard water, which is a bonus for guppy keepers. Before dosing, I recommend a 20% water change to reduce the organic loadâthis makes the medication more effective against the pathogens.
Snail Warning!
While eSHa 2000 is generally safe for fish, it is not safe for most fancy snails (like Nerites or Mystery snails) if they are already stressed. Common "pest" snails like Bladder or Ramshorn snails are usually fine, but if you have a prized snail, move it to a different tank for the duration of the treatment.
Common Signs of Healing
- The "Cotton" Falls Off: If treating for Mouth Fungus or Body Fungus, you'll see the white fluff detach.
- Activity Level: Guppies that were "clamping" their fins or hovering near the surface should start swimming through the mid-water colum again.
- Color Return: The pale, greyish look of a sick guppy should fade back into their natural vibrant colors.
Conclusion
eSHa 2000 is an essential part of a guppy-keeper's first aid kit. It acts fast, handles the "unknowns," and helps those beautiful tails heal quickly. Always follow the full 3-day course, even if the fish looks better on Day 2, to ensure the infection doesn't return.
