Care guide, husbandry, breeding, disease, sourcing, and tankmate intelligence on Arrowhead Plant - written by the Fast Aquatics editorial team and cross-verified against vendor records on the live marketplace.
Arrowhead Plant (Sagittaria latifolia) is a pond species kept by aquarists for outdoor pond stocking. Hardy and forgiving of typical beginner mistakes when given proper water chemistry.
Where Arrowhead Plant comes from
Arrowhead Plant (Sagittaria latifolia) is a hardy aquatic plant suited to outdoor pond environments. Naturally found in slow-moving waters, marshes, and pond margins across temperate and tropical zones. Used in ornamental pond design for visual interest, biological filtration, and providing cover for fish.
Arrowhead Plant tank size and setup
Arrowhead Plant requires a minimum of 200 gallons (pond) for healthy adults. The minimum is based on the species' adult size (24 inch height), territorial range, and behavior pattern. Most Arrowhead Plant sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.
For a Arrowhead Plant setup: outdoor pond with appropriate depth (3+ feet for cold-climate winterization), filtration sized 1.5-2x pond volume per hour, UV clarifier for green-water control, surface skimmer for leaf litter, and either a bottom drain or annual full cleanout.
Arrowhead Plant prefers pond parameters appropriate to your climate zone: Temperature: 50-78°F seasonal swing acceptable for cold-tolerant species; tropical pond species need 70°F+ year-round. pH: 7.0-8.5 Ammonia + nitrite: Both 0 ppm Nitrate: Under 40 ppm in established ponds Dissolved oxygen: 5+ mg/L (aerator non-optional in summer)
Pond water chemistry shifts with rainfall, leaf decay, and bioload. Test biweekly during active season; perform 10-25% water changes monthly to maintain stable parameters.
What Arrowhead Plant eats
Arrowhead Plant is a photosynthetic. Powered primarily by photosynthesis through symbiotic zooxanthellae living in the tissue. Supplemental feeding of reef foods supports faster growth but is optional once light + parameters are dialed in. Feed Arrowhead Plant appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.
Arrowhead Plant tankmates and compatibility
Arrowhead Plant is compatible with similar-temperament pond fish at appropriate stocking. Mixing predatory species (largemouth bass) with smaller pond fish (minnows, juvenile koi) creates a food chain. Plan stocking around adult sizes and territorial behaviors.

Arrowhead Plant adult size and lifespan
Arrowhead Plant reaches 24 inch height at adulthood with a captive lifespan of perennial years with proper care. Pond fish often outlive their owners under proper care - koi can live 25-50+ years with stable parameters.
Can you breed Arrowhead Plant?
Arrowhead Plant propagates through tubers, runners, or division depending on the plant. Most aquatic plants propagate freely once established; trim and replant healthy growth in spring.
Common Arrowhead Plant diseases and problems
Arrowhead Plant can develop pond-specific issues: parasites (ich, costia, trichodina), bacterial infections (ulcers, fin rot), and seasonal stress around water temperature transitions. Maintain stable temperature changes (no more than 5°F per day during seasonal shifts), feed appropriately for water temperature, and inspect fish during spring restart for signs of overwintering damage.
