What is a Monster Clown Loach?

A Monster Clown Loach is a Clown Loach that exceeds 12" in length. These fish are also referred to as tiger botia, or scientifically as Chromobotia macracanthus. This fish is native to the islands of Sumatra and Borneo, and is a popular fish for freshwater aquariums.

How big do Monster Clown Loaches get?

Clown Loaches that are considered “Monster” span from 12-16" in length. Only Clown Loaches that live in the wild have been known to reach 16". In captivity, it is more common to see a Monster Clown Loach of around 12".

Care Requirements

Monster Clown Loaches share the same care requirements as any other sized Clown Loach. These are active fish, and will school when kept in large groups. In the wild, these fish live in clear streams throughout the islands of Sumatra and Borneo. In an aquarium, you’ll want to re-create these conditions. You’ll want to provide an aquarium of at least 120 gallons, temperatures between 75°-85° and a pH level between 6-7.5. These fish prefer soft water, but can adapt to hard water conditions. The aquarium should be fully cycled, and Ammonia and Nitrite levels should be 0.

What do Monster Clown Loaches eat?

As bottom-dwellers, these fish will eat sinking shrimp pellets and algae wafers. They will also consume leftover fish food, as well as frozen foods such as bloodworms and brine shrimp.

How often should I feed a Clown Loach?

Monster Clown Loaches should be fed at least once a day, but will appreciate twice-a-day feedings. As a bottom-dweller, you’ll want to make sure they have access to food along the substrate.

Tankmates

Monster Clown Loaches are a peaceful species, and an increase in size does not correlate to an increase in aggression. These fish will do great with many other peaceful aquarium species.

Clown Loach Breeding

Clown Loaches rarely breed in captivity, but it is possible to breed this species. If you’re fortunate enough to have a breeding pair, and can provide pristine water and live food such as baby brine shrimp for the fry, you have a small chance of successfully breeding this species. Raising the fry successfully is a challenging, yet rewarding endeavor.

How long till they can breed?

As a long-living fish, the Clown Loach isn’t considered to be sexually mature until they are at least 10 years of age. However, this is just an estimate, as this age varies depending on the provided water conditions.
