Treating Cichlids with eSHa 2000: Ulcers, Fungus & Skin Irritation

A heavy-duty treatment plan for massive Oscars, delicate Discus, and vibrant African Cichlids.

Cichlids are the champions of aquarium personality, but their aggression and messy habits can lead to health disasters. A single scrap between territorial Mbunas or a sharp rock in an Oscar tank can create an open wound that quickly becomes infected with fungus or bacteria. If you see white patches, protruding eyes, or red skin sores, you need an expert solution.

eSHa 2000 is built for these high-stakes moments. It treats primary and secondary fungal infections (Cotton Wool Disease), bacterial skin infections, and skin irritation. For Cichlid keepers, it’s the "Swiss Army Knife" of medications, perfect for when you need a broad-spectrum fix for large, expensive fish.

The Ulcer Concern

Many large Cichlids are prone to "ulcers"—open, red sores that look like a piece of the fish’s skin has been scooped out. This is a severe bacterial infection. Left alone, it can lead to septicemia. eSHa 2000's formula is designed to penetrate the tissue and halt the bacterial bloom, allowing the fish’s own immune system to begin the heavy lifting of repair.

Dosing for Large Tanks?

Cichlid tanks can be massive. Counting drops is tedious and error-prone. Use our calculator to find the exact dose in milliliters or fluid ounces for your specific setup.

Specific Cichlid Advice

African Cichlids (Malawi/Tanganyika)

African Cichlid environments are naturally alkaline (high pH). Some antibiotics lose their potency in hard water. eSHa 2000 is formulated to remain active and stable across a wide pH range, meaning it works just as well in a hard water Mbuna tank as it does in a soft water community tank.

Discus and Angelfish

Discus are often considered "fragile," but they are actually just sensitive to chemical shock. When treating Discus with eSHa 2000, stagger the dose. Instead of pouring it all in at once, mix your calculated dose in a pitcher of tank water and slowly pour it into the filter intake over 15-20 minutes. This gives the fish time to adjust their osmotic regulation.

Oscars & Large South Americans

The "organic load" (waste) in an Oscar tank is massive. To ensure the medication isn't neutralized by waste, perform a 40% water change and vacuum a section of the substrate before your first dose. Medication works best in clean water.

Don't Ignore the Air!

Large Cichlids breathe heavily. Medication reduces the dissolved oxygen in the water. Add an extra air stone or increase surface agitation. If your Cichlid is hanging at the surface, they are suffocating, not reacting to the meds. More bubbles = safer fish.

Step-by-Step Cichlid Healing Routine

  1. Remove Carbon: Take out any chemical filtration (Carbon, Chemipure, Purigen).
  2. The Course: Follow the full 3-day eSHa 2000 routine. Day 1 is the high-strength "knock-back" dose; Day 2 and 3 are follow-up maintaining doses.
  3. Observation: Watch for the "white fuzz" to fall off and red sores to start turning pink/skin-colored.

Conclusion

eSHa 2000 is a reliable partner for any Cichlid owner. It’s effective, filter-safe, and designed to handle the multi-pathogen infections that often follow territorial disputes. Treat early, keep the oxygen high, and your Cichlids will be back to ruling their kingdom in no time.
