How many neons?

[Starry]

from saltwaterfish.c@m

"A group of neon gobies kept in the same tank will readily pair off and spawn, although it is wise to keep seven or more in a large tank so as to avoid any one individual being the target of too much inter-species aggression (one neon goby per 25-30 gallons is a good rule of thumb in my experience). A confirmed pair of neon gobies may be kept in a much smaller aquarium."

I had 3 in my tank, guess they were all males as I soon had 1.
