Description
In order to build a complete underwater ecosystem you need to put some fish and shrimps in your planted aquarium. There are so many fish and shrimps to choose from, from those that eat algae to those that preffer schooling and swimming all day. Otocinclus affinis it's a well known catfish that will keep some algae on check, specially brown algae (diatoms). They are quite small, maximum size of 4cm (1.5") and they are really peacefull. You should keep at least a group of 5 (depending on the size of your aquarium).
