Some notes on the stats:
• Common name: This is the name usually used in the aquarium trade. Many species go by a number of common names. Use the scientific name as the final guide to identifying your fish.
• Scientific name: All fish are assigned a two-part scientific name. As the relationships between species are revised, new scientific names are sometimes assigned. The scientific names used for each species were correct at the time of writing, but may not be the most current.
• You can use the fishbase site (www.fishbase.org) to find the current valid scientific name of a species.
• Many water parameter values and habitats are taken from the fishbase site (www.fishbase.org). They have the most extensive and current data available.
