how big

  • We are currently upgrading MFK. thanks! -neo
7 inches is big, probs the norm is around 5". They prefer to be in groups of 3 or more, I would say a min of 30gal for 3. Provide plenty of hide spots during the day and invest in some blue LED lighting to see them go for it with their synchronised dancing swim on a night - great to watch.
