Green Dust Algae
Chlorophyta spp.
Fine, powdery green coating on the glass that wipes off easily but returns quickly. Different from Green Spot Algae — much softer and more responsive to physical removal. A large clean-up crew (nerites, Mystery snails, Otocinclus) keeps it in check. Usually a sign of moderate light excess.
Green Lace Shrimp
Atyoida pilipes
Green Neon Rasbora
Microdevario nanus
Green Phantom Pleco
Hemiancistrus subviridis
Green Spot Algae
Coleochaete orbicularis
Hard, dark green circles on glass and slow-growing plant leaves — familiar to virtually every planted tank keeper. Caused by low phosphate (counterintuitively) and high light. Nerite snails are the most effective control. A small amount is considered normal and harmless.
Green Spotted Puffer
Dichotomyctere nigroviridis
Green Terror Cichlid
Andinoacara rivulatus
Green Tiger Barb
Puntigrus tetrazona
Green Tiger Lotus
Nymphaea lotus Green
Green Water (Algae Bloom)
Chlorella spp.
Pea-soup green tank water caused by a bloom of free-floating unicellular algae. Usually triggered by a combination of high nutrients and direct sunlight. A UV steriliser will clear it within days. A 3-day blackout is an alternative. Daphnia (water fleas) can be added to a fishless tank as biological control.
Guenther's Notho
Nothobranchius guentheri
Guntea Loach
Lepidocephalichthys guntea
Hair Algae
Oedogonium sp.
Fine, bright-green strands that drape over plants and hardscape. One of the most common new-tank algae — usually caused by excess light, nutrient imbalance, or lack of fast-growing plants competing for nutrients. Nerite snails, Amano shrimp, and Florida Flagfish make short work of it.
Half-Black Angelfish
Pterophyllum scalare
Hammer Coral
Euphyllia ancora
Harlequin Tusk
