Meet the Borneo Sucker: The Living Suction Cup

If you are looking to move beyond standard bottom-dwellers, the Borneo Sucker brings unmatched personality and utility to your tank. Their hydrodynamic, dorsoventrally flattened body shape is a direct evolutionary adaptation to the torrential riverbeds they inhabit in the wild.

Instead of swimming through open water like conventional fish, they use a unique gliding motion to surf from stone to stone. Their brilliant color form features a dark charcoal or rich brown body dusted with beautiful white, green, or cream-colored spots, making them an instant conversation starter in any tank.

Beginner Care & Habitat Setup

While the Borneo Sucker is a hardy fish, long-term success relies on replicating a few key characteristics of their native cold-water streams.

The Importance of Flow and Oxygen

Unlike many standard community fish, Borneo Suckers cannot thrive in stagnant, low-flow water. They require highly oxygenated water to breathe comfortably. We highly recommend using an oversized canister filter, a strong hang-on-back filter, or adding a small powerhead/wavemaker to keep the water moving swiftly. Aim for a water turnover rate that keeps the surface agitated and sparkling clean.

Substrate and Aquascaping

• Substrate: Always choose smooth sand or fine, rounded gravel. Coarse substrates with sharp edges can scrape their delicate underbellies as they glide.

• Decor: Arrange plenty of smooth river stones, pebbles, and aged driftwood. These materials give them structural territory and act as the perfect canvas for growing their favorite food.

• Plants: While plants are rare in their rapid native environments, hardy species like Anubias or Java Fern are excellent choices. They can easily be anchored to rocks or wood and their broad leaves provide perfect additional grazing shelves.

Crucial Beginner Warning: Borneo Suckers are spectacular climbers! Thanks to their suction-cup design, they can easily scale the glass and find their way out of an open tank. A tight-fitting aquarium lid is strictly required.

Diet and Feeding Strategy

Borneo Suckers are active, specialized grazers. Their natural diet consists almost entirely of benthic algae and the microscopically rich biofilm (aufwuchs) that coats submerged surfaces.

Because they rely so heavily on this built-in food source, never introduce a Borneo Sucker to a brand-new, biologically immature aquarium. Wait until your tank has established a healthy film layer on the glass and rocks.

To round out their diet in captivity, you should feed them daily. Since they can sometimes take a few days to recognize processed foods, consistency is key:

• Primary Supplement: High-quality sinking algae wafers and herbivore pellets.

• Fresh Treats: Blanched vegetables like zucchini or spinach attached to a veggie clip at the bottom of the tank.

• Proteins (Occasional): High-protein foods can cause digestive stress if overfed. Limit treats like frozen daphnia or brine shrimp to once a week.

Perfect Tankmates

Because of their exceptionally peaceful disposition, Borneo Suckers will never bother their neighbors. However, because they require cooler temperatures and fast-flowing water, you must choose tankmates that enjoy the same active environment. Excellent choices include:

• White Cloud Mountain Minnows

• Small Danios and Rasboras

• Other Hillstream Loach species

• Peaceful freshwater Gobies

• Dwarf Shrimp and Freshwater Snails
