I've heard two different answers to the same question so I thought I'd get a bigger sample size (hopefully) by asking here on the forums:
I have a maroon clown who is about 2-3 years old. This clown was the male in a mated but not breeding pair that I bought together. The female died shortly after I got the two. He is about 2-1/2 inches long and very solid looking.
I also recently bought a tank with a very young, small Piscasso clown who is only about 1"-1-1/4" long and pretty slight.
I'm trying to put the clowns together in my 65 gallon but they are not getting along. The maroon clown chases, bites and pesters the Piscasso constantly. The poor Piscasso is hiding up at the very top near the overflow.
After two days, I put the Piscasso back in my quarantine tank to give it a rest from the other fish.
I heard that the Maroon, being larger, will be dominant and become the female and the two will pair up.
I also heard that the Maroon is already male and cannot change sexes now. The smaller fish cannot become female because its smaller and therefore will never be dominant.
I've considered trading the Picasso at the LFS and getting a Maroon female (I like the Maroon better as far as looks)
What do people think?
