How many fish?

It is really important not to over-stock your aquarium. Keeping too many fish can cause water quality issues, fish health problems and can lead to territorial fighting and fin nipping that can lead to disease outbreaks.

When you buy your new fish research how big they will eventually grow and take that into consideration. What starts out as a little cutie could grow into a beast!
