Compatible Livestock
Peaceful algae grazers that won't uproot or damage delicate crypt leaves
Gentle invertebrates that graze algae without harming plants; enhance planted tank aesthetics
Small, peaceful fish that add color without disturbing substrate or plant structure
Excellent companion plant with similar low-light tolerance and slow growth rate
Compatible foreground/midground plant that thrives in same low-light conditions
Creates layered foreground effect; both species benefit from similar nutrient and lighting needs
Common Diseases
Cryptocoryne Rot (Melt)
Leaves turn translucent, mushy, and dissolve; plant appears to deteriorate rapidly after introduction
Maintain stable water parameters (temperature, pH, hardness); perform 25% water changes; remove affected leaves; ensure adequate water circulation without direct flow on plant
Nutrient Deficiency
Yellowing or pale leaves, stunted growth, loss of leaf color and vibrancy
Dose all-in-one fertilizer or macronutrient supplements (NPK); add root tabs if substrate is inert; increase lighting slightly to support photosynthesis
Algae Overgrowth
Green or brown algae coating leaves, reduced light penetration, plant appears smothered
Reduce lighting duration to 6-8 hours daily; perform water changes; introduce algae-eating fish (Otocinclus) or shrimp; manually remove algae with soft brush
Black Beard Algae (BBA)
Dark red or black fuzzy growth on leaf tips and edges, plant appears weakened
Increase water circulation; reduce photoperiod; dose liquid carbon (glutaraldehyde) or hydrogen peroxide spot treatment; manually remove affected leaves; ensure adequate CO2 if using pressurized system
