6. Hikari Cichlid Excel
Best for: Goldfish that benefit from additional plant-based nutrition
Despite being formulated for herbivorous and omnivorous cichlids, Hikari Cichlid Excel has earned a place in many experienced goldfish keepers’ feeding rotations because of its balanced ingredient profile. The pellets combine quality fish proteins with wheat germ, spirulina, alfalfa, and seaweed, providing both animal- and plant-based nutrition that aligns well with the omnivorous nature of goldfish.
Wheat germ is especially valued because it is highly digestible, even in cooler water temperatures where goldfish metabolism naturally slows. Spirulina contributes antioxidants and naturally occurring carotenoids that help maintain healthy coloration, while vitamins A, D3, E, and stabilized vitamin C support normal immune function and overall health.
Although this food was not developed specifically for goldfish, it works well as part of a varied feeding schedule rather than as the sole daily diet.
Pros
- Good balance of protein and plant ingredients
- Wheat germ supports easy digestion
- Contains spirulina for natural color enhancement
- Rich in essential vitamins and minerals
- Suitable as part of a rotating diet
Considerations
- Designed for cichlids rather than goldfish
- Best used alongside a dedicated goldfish staple food
7. Hikari Blood Red Parrot+
Best for: Enhancing natural coloration
Goldfish naturally develop brighter colors when they receive adequate nutrition and appropriate environmental conditions. Hikari Blood Red Parrot+ is commonly used by advanced hobbyists as a supplemental food because it contains multiple naturally derived pigments that support red, orange, and yellow coloration.
Its recipe includes krill, astaxanthin, lutein, marigold extract, paprika, and other carotenoid-rich ingredients that contribute to pigment development without relying heavily on artificial color additives. Probiotics and quality protein sources further support healthy growth and digestion.
Since this food emphasizes color enhancement, it is most effective when offered a few times each week rather than replacing a complete staple diet.
Pros
- Rich in natural carotenoids
- Helps maintain vibrant coloration
- Includes probiotics for digestive support
- High-quality marine protein ingredients
- Works well in a varied feeding routine
Considerations
- Intended primarily as a supplemental food

8. Frozen Fish Food
Best for: Protein-rich variety and natural feeding behavior
Frozen foods closely resemble many of the small aquatic animals goldfish consume in natural environments. Common options include brine shrimp, daphnia, bloodworms, mysis shrimp, and krill. These foods provide highly digestible protein while retaining much of their natural moisture, making them an excellent supplement to prepared diets.
Among these choices, daphnia and spirulina-enriched brine shrimp are especially valuable because their exoskeletons contribute dietary roughage that helps support normal digestion. Bloodworms are highly palatable but should be fed in moderation due to their higher protein content.
Most frozen foods are sold as individual cubes, making portion control simple. Always thaw frozen food before feeding and avoid adding excess thawing liquid to the aquarium to minimize unnecessary nutrient buildup.
Pros
- High-quality source of animal protein
- Encourages natural foraging behavior
- High moisture content supports hydration
- Adds variety to weekly feeding
- Available in several nutritious options
Considerations
- Requires freezer storage
- Should supplement—not replace—a complete prepared diet
9. Vegetables
Best for: Increasing dietary fiber
Plant matter plays an important role in a balanced goldfish diet, particularly for fancy varieties that may be more prone to digestive issues because of their compact body shape. Offering vegetables several times each week increases fiber intake and encourages natural grazing behavior.
Suitable choices include blanched zucchini, spinach, romaine lettuce, green beans, and shelled peas. Blanching tougher vegetables softens the texture, allowing fish to graze more easily while preserving much of their nutritional value.
Peas are frequently recommended by hobbyists for fish experiencing temporary constipation. While they can be useful as part of a high-fiber meal, they should not be viewed as a universal treatment for buoyancy problems, since swim bladder disorders can have many different underlying causes.
Removing uneaten vegetables after several hours helps maintain good water quality.
Pros
- Excellent natural source of fiber
- Supports digestive health
- Encourages grazing behavior
- Inexpensive and readily available
- Adds dietary variety
Considerations
- Should be prepared before feeding when necessary
- Uneaten portions should be removed promptly
10. Leftover Plants and Algae
Best for: Natural enrichment and supplemental nutrition
Goldfish spend much of their day browsing for edible material, making aquarium plants and naturally occurring algae valuable sources of enrichment. Fast-growing floating plants such as duckweed, frogbit, water lettuce, and excess stem plant trimmings are commonly consumed by goldfish and can provide additional vitamins, minerals, and fiber.
Likewise, soft green algae growing on rocks or decorations is often grazed throughout the day. This constant browsing more closely reflects natural feeding behavior than relying solely on scheduled meals.
Not every aquarium plant can withstand goldfish, however. Delicate species are often eaten quickly, while tougher plants such as Anubias, Java fern, and some larger Cryptocoryne species generally tolerate grazing better.
Plant material should complement a complete commercial diet rather than replace it, since aquatic vegetation alone cannot provide all of the protein and essential nutrients goldfish require for long-term health.
Pros
- Encourages natural grazing behavior
- Provides supplemental fiber and micronutrients
- Reduces plant waste from aquarium maintenance
- Offers environmental enrichment
- Can supplement regular feedings between meals
Considerations
- Does not provide complete nutrition by itself
- Soft plants may be consumed rapidly by larger goldfish
