Spotted Hoplo Fish Guide
The Spotted Hoplo (scientific name Megalechis thoracata) is an armored catfish with a brown body covered in dark spots and stripes. It is popular because it looks interesting, is active, and can live in many tank conditions. The fish is unique because it can breathe air from the surface, and males build foam (bubble) nests when they breed.
Spotted Hoplo Origin
- Comes from South America — the Amazon, Orinoco, and nearby rivers, and some coastal rivers in the Guianas and northern Brazil.
Temperament
- Mostly peaceful and active at the bottom of the tank
- Can become a little protective during breeding when males guard the bubble nest
Compatibility
- Good with medium or large peaceful community fish (for example, bigger tetras, barbs, rasboras).
- Avoid tiny fish (that can fit in the Hoplo’s mouth) and very aggressive or large cichlids that might bully or eat it.
Spotted Hoplo Price Range
- Typical international retail prices for adults are often USD 12–35, depending on size and morph (normal vs albino). Converted and allowing for import/shipping in India, a reasonable estimate is ₹600 — ₹2,500 per fish, depending on size and availability.

PH Level
6.5 - 7.5
Tank Type
- Freshwater only
Spotted Hoplo Aquarium Size
- Minimum recommended: 120 cm / 4 ft long tank for adults or a tank of 100–150 litres if keeping a small group. They need space to swim and dig.
Water Conditions
- Temperature: 22–28 °C (72–82 °F)
- pH level: About 6.0–8.0 (slightly acidic to neutral)
- Water hardness: Soft to moderately hard (approx 4–12 dGH)
Spotted Hoplo Environment Needs
- Substrate: Soft sand is best — gentle on their long barbels.
- Decor: Plenty of shady hiding spots — bogwood, rocks, caves, and strong plants. Secure decorations so digging Hoplos don’t topple them.
- Lighting: Not too bright. Floating plants help diffuse light. A blue moon light is nice for evening viewing.
- Water flow & oxygen: They like good oxygen and moderate current; they can gulp air from the surface if oxygen is low.

Spotted Hoplo Feeding Frequency & Tips
- Feed once or twice a day.
- Give only what they eat in a few minutes.
- Scatter food in different places so that quick, hungry fish don’t steal all the food from Hoplos.
- Watch their barbels — gentle sand helps them find food without damage.

Spotted Hoplo common health issues
Ich (White Spot Disease)
Ich comes from a microscopic parasite that produces tiny white spots on the fish's body, fins, and gills. Fish that are infected might rub their bodies on the decor at the side of the tank or show rapid breathing and a lack of appetite. Recommended treatment is to slightly raise the tank temperature (if possible), perform frequent partial water changes, and add ich medication according to product instructions. People commonly use copper-based medications and other formulations that contain malachite green to treat Ich. Before use, people should evaluate other tank inhabitants for tolerability.
Fin Rot (Bacterial or Fungal)
Bacterial or fungal infection can cause fin rot. Fins look ragged, torn, or discolored because water conditions are poor or fish endure stress. The treatment includes improving water quality. Large water changes, cleaning of the filter, removing affected fish to another tank, and using a broad-spectrum anti-bacterial or anti-fungal treatment are options. These can be obtained at the fish store or from a veterinarian. Good nutrition eases recovery. Low-stress environments do so as well.
Internal Parasites / Worms
Symptoms include loss of appetite, weight loss, stringy feces, and swelling. To cure that, treat with anti-parasitic medications (either oral or medicated water). It is also recommended to quarantine the new fish and clean the tank.
Spotted Hoplo General Health Tips
- Weekly water changes of 20-30% will keep the water clean. The water will be healthy with these changes.
- Use a good filter, don't overfeed.
- New fish should be quarantined for 2 to 3 weeks before they are introduced to the main tank.
- Watch behaviour daily — early detection of problems makes treatment easier.
- Since Hoplos can breathe air, ensure a small open gap to the surface and steady oxygen in the water when medicating.
