I have had a baby swordtail, Nemo, for a while. A few months. I was wondering how big I should let him get before he is released out of the little separate tank I have in my big tank.
He is about the size of some guppies I got recently. The new fish arent what I'm scared of. I'm scared of my filter sucking him up. Also, I have a pretty big chinese algae eater who does like to scare the 3 other adult swordtails I have, Maureen, Yuki, and Yellow Submarine.
Here is a picture of him in the little tank I have had him in since he was just born. Yes, it is green. I purchased it that way.
