Ammannia Gracilis
Ammannia gracilis
Plantae›Tracheophyta›Magnoliopsida›Lythraceae
📍 West Africa
A beautiful stem plant that produces elongated, lance-shaped leaves with an olive-green to reddish-pink coloration. Under intense light and CO2 supplementation the leaves turn a rich red-orange, creating striking contrast with green plants. A staple in competition Dutch aquascapes.
Tank Mates
Peaceful algae grazers that won't damage plant leaves and help maintain tank cleanliness
Gentle invertebrates that graze on algae without harming healthy plant tissue
Peaceful dwarf cichlid that forages on substrate without uprooting or damaging stem plants
Schooling fish that occupy mid-water column and do not interact destructively with plants
Complementary stem plant with similar care requirements and compatible growth patterns
Hardy foreground/midground plant that thrives under identical water parameters and lighting
Common Diseases
Nutrient Deficiency (Nitrogen/Iron)
Yellowing leaves, stunted growth, pale new growth, reduced red coloration
Increase fertilizer dosing with emphasis on nitrogen and iron supplements; ensure adequate lighting and CO2
Algae Overgrowth on Leaves
Green or brown algae coating leaf surfaces, reduced photosynthesis, plant decline
Reduce lighting duration to 8–10 hours daily, increase water changes, add algae-eating fish or shrimp, improve water circulation
Melting (Tissue Decay)
Leaves becoming translucent, mushy stems, rapid tissue breakdown after planting
Gradually acclimate plant to new conditions over 2–3 weeks; maintain stable water parameters; ensure adequate CO2 and nutrients
Poor Coloration
Leaves remain green instead of developing red/pink hues despite adequate growth
Increase lighting intensity to medium-high (8–10 hours daily); boost micronutrient fertilization; ensure stable temperature and CO2
