thanks igotsalt but my guess is that clarkyclown's fish is already a female and specially is been in the tank alone. With Maroon you have to get a very small pair for her to take or if you put two females then one will kill the other. You see that I did not say the bigger one will kill the smaller one because size of female does not matter in some cases. Few months ago I introduced two maroons to each other and the smaller one almost killed the bigger one. I guess it depends how old, how strong (system they were in). Which one was in the tank first and has no transfer stress.
igotsalt : your mailbox is full and I sent you an email replies yesterday and today. You might want to go to your mailbox and open them all and not only 5 days or two weeks and delete some or all. You also might want to delete some from your sent box too. I just did a backup of my PM's and deleted them few days ago.
