Compatible Livestock
Small, gentle shrimp that graze algae without uprooting delicate plants; beneficial for tank maintenance
Larger shrimp that consume algae and detritus without damaging carpet plants; ideal for planted tanks
Small, peaceful algae-eating fish that won't uproot plants; requires established biofilm
Tiny, non-aggressive schooling fish that navigate around carpet plants without causing damage
Companion carpeting plant with similar care requirements; creates layered aquascaping effect
Slow-growing foreground plant that complements carpet layouts; can be tied to hardscape
Common Diseases
Nutrient Deficiency (Iron/Macronutrient)
Yellowing leaves, stunted growth, pale coloration, necrotic spots on new growth
Increase fertilizer dosing; test water parameters; ensure adequate light and CO₂; perform 25-30% water changes weekly
Algae Overgrowth (Green/Black Beard)
Green or black fuzzy coating on plant surfaces; reduced light penetration; plant deterioration
Reduce photoperiod to 6-8 hours; increase water flow; manually remove algae; add algae-eating shrimp; improve nutrient balance
Melting (Osmotic Shock)
Rapid leaf dissolution, plant disintegration, mushy stems within days of planting
Gradually acclimate plant over 2-3 weeks; maintain stable water parameters; ensure high CO₂ and light; avoid drastic parameter changes
Root Rot (Poor Substrate Conditions)
Blackened roots, slow growth despite adequate lighting, plant lifting from substrate
Improve substrate with nutrient-rich base layer; ensure adequate water circulation; dose root tabs; reduce organic debris accumulation
