Target Feeding Corals

This guide covers target feeding corals with practical steps for home aquariums. Target feeding delivers meaty foods directly to coral polyps — growth and color improve when done consistently without overloading the system.

Which Corals to Feed

Large polyp stony corals, many soft corals, zoanthids, and non-photosynthetic species benefit from direct feeding. Purely photosynthetic SPS often need only light and dissolved organics.

Watch polyp extension after lights dim — extended tentacles signal feeding readiness.

Food Choices

Frozen mysis, cyclops, coral-specific powders, and amino acid supplements are common. Thaw and mix to a slurry thin enough for pipettes or turkey basters.

Rotate foods rather than relying on one brand — variety covers amino acid profiles better.

Technique

Turn off return pump or reduce flow for 10–15 minutes so food settles on polyps. Use a small pipette to deposit slurry directly on tentacles, not sand.

Feed one section per night on large reefs to distribute nutrient load. Resume flow afterward to flush unfed residue toward skimmers.

Schedule and Amount

Twice weekly feeding suits many LPS displays; NPS corals may need daily or continuous dosing. Observe polyp response and adjust — rejection means food type or timing is wrong.

Less is more on new tanks with immature export — nutrient spikes fuel algae faster than they grow corals.

Water Quality Monitoring

Test phosphate and nitrate weekly when feeding heavily. Increase skimmer wetness or water change volume if nutrients climb.

Healthy fed corals show thicker tissue and faster skeletal growth — track alkalinity consumption too on stony species.
