Feeding &
Nutrition

Overfeeding is one of the most common causes of algae, poor water quality, and livestock loss. Feeding should support the entire ecosystem — not just the fish you see.

General Feeding Principles

  • Feed small amounts, consistently
  • Observe how quickly food is consumed
  • Remove uneaten food where possible
  • Adjust feeding based on tank size, stock, and filtration
  • More food does not equal a healthier tank

Rule of ThumbIf food isn't eaten within a few minutes, you're likely feeding too much.

Feeding Live Aquarium Food

Live foods behave differently to dry feeds. They stimulate natural hunting behaviour, reduce waste, and allow fish to feed at their own pace.

  • 1–3 times per week for most community tanks
  • Daily feeding suitable for breeding, grow-out, or predator setups (with experience)
  • Live food should supplement, not always replace, a varied diet

NoteIncreased live feeding always requires increased maintenance and observation.

Feeding Live Snails

Add snails gradually rather than all at once. Allow fish to hunt naturally. Remove uneaten remains if required. Predatory fish self-regulate better when food is introduced slowly rather than in bulk quantities.

Dry Feed Best Practice

  • Feed once or twice daily
  • Only what fish consume within 1–2 minutes
  • Rotate food types for nutritional balance
  • Store correctly to prevent moisture and nutrient loss

ImportantIf water quality declines, feeding is usually the first thing to reassess. Adding filtration won't fix chronic overfeeding.

Feeding by Tank Type

Community

Light, regular feeding. Mix of dry food and occasional live feed. Observe slower feeders.

Predator / Semi-Aggressive

Larger portions, less frequently. Live food introduced gradually. Monitor waste buildup.

Breeding & Grow-Out

More frequent feeding. Increased live food use. Extra filtration and water changes required.

Signs You're Feeding Too Much

  • Uneaten food collecting on the substrate
  • Cloudy water
  • Algae spikes
  • Snail population explosions
  • Fish appearing bloated or lethargic

Quick Reference

  • Feed small amounts, consistently
  • Most fish only need food once or twice daily
  • Food should be consumed within 1–2 minutes
  • Live food works best as a supplement
  • Introduce live snails gradually
  • When in doubt — feed less, observe more, adjust slowly

Important Context & Expectations

Feeding outcomes vary between tanks. Livestock health, growth, and behaviour depend on tank conditions, stocking density, filtration capacity, and feeding volume. Live food and snails are supplied in good health at dispatch. Once introduced, responsibility for outcomes lies with the keeper.
