Recommended Diet Types
During boarding, the diet should closely mimic the fish's usual food to minimize stress. Choose from high-quality dry flakes or pellets designed for the specific species (e.g., cichlid pellets, goldfish flakes). Freeze-dried or frozen foods like bloodworms, brine shrimp, and daphnia can be offered as treats. Avoid live foods unless the fish is accustomed to them, as they may introduce pathogens. For herbivorous fish, provide spirulina-based pellets or blanched vegetables.
Portion Sizes and Daily Caloric Needs
Fish have small stomachs and require small, frequent meals. A general rule is to feed only what the fish can consume in 2-3 minutes. Overfeeding can pollute the water; underfeeding may cause malnutrition. Caloric needs vary by species, size, and activity. For example, a 5-inch goldfish needs about 10-20 calories per day, while a small tetra requires less than 5. Adjust portions based on water temperature (warmer water increases metabolism) and activity level.
| Fish Size | Daily Pellet Amount |
|---|---|
| Small (1-2 inches) | 2-3 pellets |
| Medium (3-5 inches) | 5-8 pellets |
| Large (6+ inches) | 10-15 pellets |
Divide this daily amount into 2-3 feedings.
Feeding Frequency and Schedule
Feed adult fish twice a day (morning and evening). Juveniles require 3-4 small feedings daily. Stick to a consistent schedule to reduce stress. Use an automatic feeder if the boarding period exceeds a few days, ensuring it dispenses the correct amount.
Essential Nutrients
- Protein: For growth and repair; vary from 30-50% depending on species.
- Fats: Omega-3 and omega-6 for energy and immune health.
- Carbohydrates: Provide energy; some fish need low carb diets.
- Vitamins: A, D, E, K, B-complex; vitamin C is crucial.
- Minerals: Calcium, phosphorus, iodine, iron for bone and metabolic health.
Toxic Foods and Ingredients
Never feed fish bread, crackers, meat scraps, or sugary foods. Avoid foods high in starch, salt, or preservatives. Some human foods like avocado, chocolate, and garlic are harmful. Always use species-appropriate commercial foods.
Water Intake Recommendations
Fish absorb water through gills and skin, so maintain clean, dechlorinated water with proper pH and temperature. Ensure the tank has good filtration and perform partial water changes every week during boarding.
Useful Supplements
- Spirulina powder: great for herbivores and boosts color.
- Garlic extract: known to boost immunity and appetite.
- Vitamin C drops: reduce stress and prevent deficiency.
- Probiotics: improve digestion and water quality.
Feeding Differences by Life Stage
Juveniles need high-protein foods (50-60%) and more frequent feedings. Adults require balanced protein (30-40%) and less fat. Seniors have slower metabolisms; feed lower protein (25-30%) and easily digestible foods. Adjust portion sizes to prevent obesity.
Signs of Healthy vs. Unhealthy Diet
Healthy diet results in vibrant colors, active swimming, normal feces, and good growth. Unhealthy signs include lethargy, faded colors, clamped fins, bloating, or erratic swimming. Poor appetite or white stringy feces may indicate malnutrition or illness.
By following this temporary feeding plan, your ornamental fish will stay healthy and stress-free during your absence.
