Scaled fish — Tilapia, snakehead, red tilapia

Hemorrhage, exophthalmia, parasites on scaled fish

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.

Effective Scaled fish (tilapia, snakehead…) farming

Quick answer

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.

pH: 6,5–8,5

Biology & model

Scaled fish: hardy but sensitive to heat & Streptococcus

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.

Environment & gas

Stabilize water, cut toxic gas — block disease source

A foul bottom and toxic gas stress fish and invite hemorrhagic infection. Bottom probiotics + gas removal + exchange keep the pond stable.

SOILMAX New

MAX 4000

YUCCA C

Hemorrhage & exophthalmia

Treat the right bacterium: Streptococcus vs Aeromonas

Exophthalmia and spiral swimming usually mean Streptococcus; hemorrhage and ulcers usually mean Aeromonas. Identify the agent to pick an effective antibiotic.

OXYTETRA

FLOR-MAX

SULTRI AQUA

Immunity & liver

Proactive prevention via immunity

Prevention beats cure: regular immunity and liver support help fish resist heat and bacterial pressure, reducing antibiotic use.

5-step farming & treatment protocol

Environment
SOILMAX New + MAX 4000 for the bottom; YUCCA C when gas is high; exchange + oxygen in hot season.
Immunity & liver
AQUAMOS + BETAGLUCAN GRO + HERB GUARD regularly; CANFORTA for vitamins.
Treat hemorrhage
Streptococcus (exophthalmia) → OXYTETRA / SULTRI AQUA; Aeromonas (ulcers) → FLOR-MAX / OXYTETRA.
Parasites
AQUA PRAZI for flukes and Trichodina; combine with water disinfection.
Disinfection
WORK 80 / POWER GLUTA on outbreak, then re-seed probiotics. Observe withdrawal.

Protocols by observed sign

Pick by what you see at the pond. Each protocol lists doses, a day-by-day schedule and the withdrawal period.

QT-01Bacillary necrosisThis 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.Withdrawal: 4 weeks

QT-02Haemorrhagic septicaemiaUnlike bacillary necrosis, this one shows from the outside: redness at the fin bases, around the vent and on the flank.Withdrawal: 4 weeks

QT-03Co-infection: haemorrhage and bacillary necrosisUsually appears after a first course that did not clear. The document names the cause plainly: a dragged-out treatment and repeated antibiotic courses.Withdrawal: 4 weeks

QT-04No antibioticWhite liver, white gill from repeated antibioticsFarmers often mistake this for a fresh bacterial infection and feed more antibiotic, deepening the loop.Withdrawal: None

QT-05No antibioticExternal parasitesThe sign is behaviour before it is a lesion: startling during feeding, and gathering into small groups swimming through each other.Withdrawal: None

QT-06Internal parasites and undigested faecesDeworm on a schedule rather than waiting for symptoms. It is the cheapest prevention in the whole crop.Withdrawal: 4 weeks

Frequently asked questions

How to treat exophthalmia in tilapia/red tilapia?

Exophthalmia 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.

Which medicine for hemorrhage and ulcers on scaled fish?

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.

Why does hemorrhagic disease peak in hot season?

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.

How to treat parasites on scaled fish?

Trichodina, flukes, fish lice → use AQUA PRAZI with WORK COP Plus or POWER GLUTA, then re-seed probiotics and add immunity support.
