more than two clownfish?

[reefwars]

i have 4 clowns in my tank a skunk ,a mated pair of cinnamons,and a large tomato.they honestly hate each other and stay to their own sides of the tank if one leaves and crosses anothers territories they attack, so the skunk stays in his anemone and the pair in the middle with the tomato on the end if my tank wasnt 6 ft long im sure they would kill each other over night.in order to get clowns of diff kinds to stay alive in the same tank you will need lots of hiding places and space, feed them where they are dont force them to leave their territory,if a fight breaks out split them up for a bit before someone losses a fin or dies.having them host things is good and bad they want to protect their investment so when another clown comes around they will fight honorably so i keep a number of things for them to host if need be.

in all honesty in a 20g tank i would stick to the less aggressive species or stick with the same ones or a tank divider they are easy to install in a small tank i had to go that route once and i just cut small holes in the divider to keep water flowing good.
