types of algae that grow in a freshwater aquariums
There are 7 main types of algae (but more do exist) that aquariums can have. Brown algae. Brown Algae. This will probably be the first type of algae any one will encounter in the aquarium and could appear from early on and will normally disappear when the tank stabilises and becomes more mature. Brown algae could be in the form of a fluff like or spot appearance on plant leaves, rocks, glass, substrate or decorations.
Green hair algae. Green Hair Algae. Is probably the most common of all algae you will come across in your aquarium and can take on many forms, from spots, hair, or bushy appearance. Light green in colour and can reach lengths of over 1 inch and if left on its own, it will cause problems.
