9 Best Foods for Catfish of 2026

Dive into nutrient-rich feeding with Tetra ShrimpWafers, a top-tier sinking wafer that delivers shrimp-powered appeal and balanced nutrition for bottom dwellers. Engineered specifically for omnivorous fish like catfish and loaches, these wafers contain stabilized vitamins and high-quality proteins that support immune health and vibrant vitality. The slow-sinking design ensures food reaches the tank floor without dissolving, directly addressing the feeding challenges many aquarists face with surface-oriented diets.

In real-world tanks, these 3-ounce wafers consistently dissolve slowly, giving bottom feeders ample time to locate and consume them—ideal for community tanks with mixed species. Each wafer softens gradually, making it accessible even to smaller corydoras or juvenile loaches. While they perform excellently in standard aquariums up to 30 gallons, heavy bio-load tanks may require supplementation due to moderate protein levels (approx. 25%). They’re best used as a daily staple for small to medium tanks, though pickier eaters might need coaxing during initial introduction.

Compared to premium options like Hikari Sinking Wafers or Fluval Bug Bites, Tetra’s version trades some protein density for broader digestibility and lower cost, making it a smart choice for budget-conscious keepers prioritizing consistency over high-growth formulas. It’s perfect for hobbyists maintaining stable, planted tanks with plecos, cory cats, or clown loaches. While not the most protein-packed option, its reliable formulation and minimal water clouding offer better day-to-day value than many pricier competitors.

When it comes to large-scale pond feeding, Purina AquaMax 2000 stands out as a heavy-duty, high-efficiency floating pellet built for serious fish growers and pond owners. With a robust 32% protein content, this formula fuels lean muscle development in catfish, bass, bluegill, and koi—perfect for those aiming to raise trophy-sized fish or maintain a thriving ecosystem. The floating design is more than just convenient; it allows for real-time monitoring of feeding behavior, helping prevent overfeeding and reducing waste buildup in large water bodies.

Field-tested across backyard ponds and semi-commercial setups, these pellets hold their shape for over 30 minutes on the surface, giving even slower feeders time to engage. The uniform 3–5mm pellet size is ideal for adult catfish and game fish, promoting natural surface feeding without clogging filters or sinking prematurely. However, in ponds with heavy wind or strong aeration, some pellets may drift, requiring strategic feeding zones. Additionally, while highly efficient, the bulk 50-pound bag isn’t practical for casual users with small water features.

Positioned against Nature’s Canvas Big Strike, AquaMax offers slightly better feed conversion and broader species compatibility, especially in mixed-species ponds. It’s the go-to for serious pond keepers managing 500+ gallon environments where consistency, growth, and water quality are paramount. Though pricier per pound than economy feeds, its minimal waste and high digestibility deliver superior long-term value compared to lower-tier alternatives.

Step into the world of precision nutrition with Zignature’s Catfish Limited Ingredient Formula—a clean-label dry food that redefines what high-end catfish feeding should look like. Featuring real catfish as the first ingredient, this grain-free kibble is rich in omega-3 fatty acids and naturally low in fat, making it ideal for fish requiring a lean, anti-inflammatory diet. The limited-ingredient profile reduces allergy risks, appealing to aquarists rotating foods or managing sensitive species in controlled environments.

In practice, this 25-pound dry food shines in indoor aquaculture systems and large tanks where consistent, high-volume feeding is required. Its crisp kibble structure resists crumbling and maintains nutrient integrity during storage, while the added probiotics noticeably improve digestion and reduce waste output. However, being a dry pellet, it doesn’t sink immediately—some bottom feeders may hesitate before consuming unless trained. Also, the lack of algae or plant matter makes it less suitable for omnivorous or herbivorous hybrids.

When stacked against Nature’s Canvas or Purina, Zignature takes a niche health-first approach, trading broad palatability for targeted wellness benefits. It’s best suited for advanced hobbyists or breeders focused on longevity, immune support, and rotational feeding strategies. While not the most enticing option for picky eaters, its fortified vitamins and gut-support blend offer a cleaner, more sustainable nutritional edge than standard fishmeal-based pellets.

Meet the undisputed workhorse of catfish feeding—Nature’s Canvas Big Strike, a floating powerhouse engineered for maximum growth, minimal waste, and effortless feeding in both backyard ponds and commercial setups. Boasting a robust 32% protein blend with balanced amino acids, this feed drives lean mass development without excess fat accumulation, making it ideal for growers aiming to raise healthy, market-ready fish. Its floating design promotes natural feeding behavior, allowing owners to observe intake and adjust portions in real time.

Real-world use confirms its exceptional durability: pellets stay intact for 20–30 minutes, resisting disintegration even in aerated ponds. The 40-pound bag offers serious volume for frequent feeders, while the high digestibility means less sludge buildup and clearer water over time. Fortified with vitamins C, E, D, and B-complex, it supports immune resilience during seasonal shifts. That said, smaller juvenile fish may struggle to bite larger pellets, so crushing may be needed for young stock.

Pitted against Purina AquaMax 2000, Big Strike holds its own with comparable protein and better palatability, thanks to its premium fishmeal and attractant blend. It’s the gold standard for serious catfish keepers who demand growth, clarity, and reliability in one package. Though slightly more expensive than budget options, its optimal nutrient absorption and rapid growth support make it the most well-rounded performer in the lineup.

Aqueon Shrimp Pellets deliver smart, no-fuss nutrition for bottom dwellers, combining sinking efficiency with clean-water performance in a compact, easy-to-store format. These 9mm sinking pellets are infused with shrimp protein and essential nutrients that attract even cautious eaters like corydoras and loaches. What sets them apart is their low-clouding formula, which maintains water clarity—a major pain point in densely stocked tanks—thanks to high digestibility and minimal filler content.

In testing, these pellets sink rapidly and remain intact for over an hour, giving nocturnal feeders like plecos and loaches time to locate them. They’re particularly effective in planted tanks and community aquariums where overfeeding can quickly degrade water quality. While not the highest in protein (around 28%), they offer a well-rounded daily diet for maintenance rather than rapid growth. However, larger catfish may consume them too quickly, leaving smaller tankmates underfed.

Compared to Tetra ShrimpWafers, Aqueon’s version offers larger pellet size and better water stability, though with slightly less flavor enhancement. It’s an excellent value-driven option for mid-sized tanks (20–40 gallons) where consistent, clean feeding is a priority. While not designed for high-growth cycles, its reliable sinking action and waste-reducing profile make it a standout in the budget-friendly segment.

For aquarists who demand clean, natural nutrition, Ultra Fresh Tropical Shrimp Pie is a game-changer in bottom-feeder feeding, offering a live-food-like experience without the biosecurity risks. Crafted with wild sword prawns, squid, seaweed, and vegetables, this additive-free, flat-format food delivers a 7:3 meat-to-vegetable ratio that mirrors natural diets—perfect for finicky eaters and fish accustomed to live prey. The no-preservatives formula softens quickly in water but resists disintegration, ensuring every bite is consumed.

In real use, this 2.05-ounce pie excels in small to medium tanks with sensitive species like corydoras, dwarf cichlids, and hillstream loaches. It sticks effortlessly to glass, allowing precise placement and reducing scatter feeding. The inclusion of 3 million CFUs/g of probiotics visibly improves digestion and reduces waste, contributing to longer water clarity cycles. However, due to its soft texture and lack of binders, it’s not ideal for automatic feeders or unattended dosing.

Stacked against Fluval Bug Bites or Hikari wafers, Ultra Fresh wins on ingredient purity and palatability, though it falls short in convenience for large or busy setups. It’s perfect for purists and breeders who prioritize natural diets and gut health over mass feeding. While more expensive per use, its high attraction and low waste deliver unmatched feeding satisfaction for discerning fishkeepers.

Hikari Tropical Sinking Wafers are the gold standard for corydoras and loach keepers, blending decades of aquatic research with a perfectly engineered sinking disc that caters to even the tiniest bottom dwellers. These wafers are packed with spirulina, silkworm, and krill, delivering a vegetable-rich, highly digestible diet that supports natural grazing behavior. The small, disc-shaped format breaks easily, making it ideal for both fry and adults—a rare balance in the wafer market.

In practice, these wafers sink fast and soften gradually, giving slow eaters like cory cats ample time to feed without the food breaking apart or clouding the tank. Their fortified vitamin C content boosts immunity, particularly during tank transitions or disease recovery. In planted tanks, the minimal residue keeps substrate clean and nitrate levels stable. However, larger plecos or big catfish may find them underwhelming in size and caloric density.

Compared to Tetra ShrimpWafers, Hikari offers superior ingredient quality and species-specific targeting, making it the top pick for dedicated cory and loach enthusiasts. While slightly pricier, its scientific backing and extreme digestibility justify the cost for those serious about bottom-feeder health. It’s not the best for large omnivores, but for small, delicate bottom feeders, nothing else matches its precision.

Fuel your catfish with insect-powered performance—Fluval Bug Bites Granules are a protein-dense, eco-conscious formula headlined by 40% Black Soldier Fly Larvae, nature’s most sustainable protein source. This first-ingredient insect boost delivers complete amino acids and omega fatty acids, promoting glossy fins, vibrant coloration, and strong immune function. The 1.4–1.6mm sinking granules are tailor-made for small to medium bottom feeders, ensuring precise portioning and minimal waste.

In real-world tanks, these granules sink rapidly and are devoured by corydoras, otocinclus, and small loaches within minutes. Their high digestibility results in less ammonia output, a boon for planted and nano tanks. Being processed in small batches in Canada, they retain freshness and avoid artificial fillers, colors, or preservatives—appealing to eco-minded aquarists. However, the 1.6-ounce size means frequent repurchasing for heavy feeders, and larger catfish may need supplemental feeding.

Versus Tetra or Aqueon options, Bug Bites offer significantly higher protein and cleaner sourcing, though at a premium. They’re ideal for hobbyists focused on natural, high-growth diets in controlled environments. While not the cheapest, their sustainable sourcing and powerful nutrition make them a standout for health-conscious fishkeepers seeking results without compromise.

Tetra PRO PlecoWafers are engineered for herbivores, offering a fiber-rich, algae-packed formula that caters specifically to plecos, bristlenose, and other plant-munching bottom dwellers. With a concentrated algae center and all-vegetable composition, these wafers deliver slow-digesting nutrition that mimics natural grazing—critical for maintaining gut health in algae-dependent fish. The sinking, slow-disintegration design ensures food stays on the substrate for hours, perfect for nocturnal feeders.

In testing, these wafers maintain integrity for over two hours, softening just enough for plecos to rasp without crumbling into dust. Their clear-water formula prevents clouding, even in heavily stocked tanks. While excellent for herbivores, they lack animal protein, making them unsuitable for omnivorous catfish expecting meat-based meals. Some users report that aggressive feeders may consume them before plecos emerge at night.

Compared to Hikari Algae Wafers or generic veggie tabs, Tetra’s version offers better sinking stability and wider availability, though with slightly less algae concentration. It’s the best daily staple for pleco owners who need reliable, consistent feeding without mess. While not a complete diet for mixed tanks, its targeted formulation and ease of use make it the top pick for dedicated algae-eater care.
