Hi, I have two 29 gallon freshwater tanks. I am looking for advice on how to tell if my pregnant swordtail is going to give birth soon. She is very rounded and squared off, yet, I can not see the gravid area because of her dark orange coloring in that area. I also have this same problem with a platy. Does anyone have any ideas as to what I should look for in her behavior, or any comments about her coloring or body shape ? Thank you...applesnail.....
