Scaled fish — Tilapia, snakehead, red tilapia
Scaled fish (tilapia, red tilapia, snakehead) easily catch hemorrhagic disease from Streptococcus/Aeromonas (exophthalmia, darkening, ulcers) and parasites when ponds are foul and hot. Solution: stable environment + immunity + treat the right bacterium.
Scaled fish (tilapia, red tilapia, snakehead) need: (1) a stable pond with SOILMAX New/MAX 4000 probiotics and YUCCA C for toxic gas; (2) immunity and liver support with AQUAMOS, BETAGLUCAN GRO, HERB GUARD; (3) hemorrhage treatment — Streptococcus (exophthalmia, spiral swimming) or Aeromonas (hemorrhage, ulcers) with OXYTETRA, FLOR-MAX, SULTRI AQUA by agent; parasites with AQUA PRAZI; disinfect with WORK 80/POWER GLUTA. Observe withdrawal.
Tilapia, red tilapia and snakehead are hardy in ponds/cages but easily break out with hemorrhagic disease in heat, high density and a waste-laden bottom.
A foul bottom and toxic gas stress fish and invite hemorrhagic infection. Bottom probiotics + gas removal + exchange keep the pond stable.
Exophthalmia and spiral swimming usually mean Streptococcus; hemorrhage and ulcers usually mean Aeromonas. Identify the agent to pick an effective antibiotic.
Prevention beats cure: regular immunity and liver support help fish resist heat and bacterial pressure, reducing antibiotic use.
SOILMAX New + MAX 4000 for the bottom; YUCCA C when gas is high; exchange + oxygen in hot season.
AQUAMOS + BETAGLUCAN GRO + HERB GUARD regularly; CANFORTA for vitamins.
Streptococcus (exophthalmia) → OXYTETRA / SULTRI AQUA; Aeromonas (ulcers) → FLOR-MAX / OXYTETRA.
AQUA PRAZI for flukes and Trichodina; combine with water disinfection.
WORK 80 / POWER GLUTA on outbreak, then re-seed probiotics. Observe withdrawal.
Decided by what you can see at the pond, no antibiogram needed. Each protocol carries exact doses, day-by-day steps and the withdrawal period.
QT-01
This one cannot be judged from the outside. Open 5–10 fish to see the white pus spots on liver, kidney and spleen — the only reliable sign.
QT-02
Unlike bacillary necrosis, this one shows from the outside: redness at the fin bases, around the vent and on the flank.
QT-03
Usually appears after a first course that did not clear. The document names the cause plainly: a dragged-out treatment and repeated antibiotic courses.
QT-04No antibiotic
Farmers often mistake this for a fresh bacterial infection and feed more antibiotic, deepening the loop.
QT-05No antibiotic
The sign is behaviour before it is a lesion: startling during feeding, and gathering into small groups swimming through each other.
QT-06
Deworm on a schedule rather than waiting for symptoms. It is the cheapest prevention in the whole crop.

OXYTETRATreats Aeromonas/Pseudomonas hemorrhage; Vibrio luminescence
FLOR-MAXFlorfenicol for bacillary necrosis (Edwardsiella ictaluri)
SULTRI AQUAAntibiotic for Vibrio luminescence, red-spot/hemorrhage
TETRA-CAntibiotic + vitamin C — treat infection, support immunity
DOXYPABroad-spectrum doxycycline for severe infection
AQUA PRAZITreats parasites: monogeneans, gill flukes, fish liceExophthalmia and spiral swimming usually mean Streptococcus — use OXYTETRA or SULTRI AQUA per dose, with water disinfection (WORK 80) and liver protection (HERB GUARD). Reduce density, boost oxygen, ease heat stress.
Hemorrhage and ulcers usually mean Aeromonas — use FLOR-MAX or OXYTETRA, disinfect with WORK 80 / POWER GLUTA, then re-seed probiotics and boost immunity. Observe withdrawal.
Heat destabilizes algae, drops night oxygen, raises toxic gas and stresses fish — favorable for Streptococcus/Aeromonas. Stabilize with probiotics, boost oxygen and raise immunity before the peak.
Trichodina, flukes, fish lice → use AQUA PRAZI with WORK COP Plus or POWER GLUTA, then re-seed probiotics and add immunity support.
