I have 3 different clown clowns in a tank, 1 false, 1 true, 1 snowflake , the true and false get along,but they have been together for about 5 years. Now, I bought the snow flake about five months ago,with the intention that it would hook up with the false, and i would take the true perc out( which was impossible) so he stayed in. When I put him in the true perc and the snow flake were fighting to the death, which went on for three days or so, and then something happened , I don't know what but they started leaving each other alone . Which bought the true and false closer together they started sleeping together, and on several accounts I've seen all three of them sleeping together.
Got to love clowns , funny fish..
