Compatible Livestock
Peaceful algae grazer; will not uproot or damage stem plants
Non-destructive; helps control algae on plant leaves
Small, peaceful schooling fish; minimal disturbance to planted layout
Algae eater that grazes without uprooting; compatible with stem plants
Complementary stem plant; similar care requirements and visual appeal
Common Diseases
Melt on Transition
Leaves become translucent, mushy, and dissolve; typically occurs after planting or during acclimation to new water parameters
Ensure stable water parameters (pH, temperature, hardness); provide high light and CO2; trim affected portions and allow new growth; avoid drastic water changes
Iron Deficiency (Chlorosis)
Yellowing of new leaves while veins remain green; stunted growth; pale coloration loss
Dose liquid iron fertilizer (chelated iron) 2-3 times weekly; ensure adequate lighting and CO2 to support nutrient uptake; check for excess phosphate which can lock up iron
Algae on Leaves
Green, brown, or black algae coating leaf surfaces; reduced photosynthesis; plant appears dull
Increase water circulation; reduce photoperiod to 8-10 hours daily; manually remove algae; add algae-eating shrimp or fish; maintain nutrient balance to prevent excess phosphate
Nutrient Deficiency (Macros/Micros)
Slow growth; pale or yellowing leaves; leaf curling or distortion; loss of red coloration
Dose comprehensive all-in-one fertilizer or separate macro (NPK) and micro (trace elements) fertilizers; perform 25-30% weekly water changes; ensure adequate lighting and CO2
