Black Mollies and Creamsicle Mollies

[argylekim]

I have 6 black mollies and 4 creamsicles mollies in the same 55 gallon tank. One of the larger mollies started to have a discoloration on the tips of his dorsal fin and tail fin. The next picture is what the other male looks like. The next pic is of the creamsicle mollie that I suspect is pregnant... Is this true? The last picture is of the mollie that could or could not be pregnant or may or may not be a girl... Thanks for any feedback!!!

For the first picture: Does the black male mollie look healthy even though he has the yellow tint to his fins? His tank mate is the second picture and does not have the discoloration like the one picture in the first picture. Secondly the picture of the creamsicle mollie is def. a female... just wondering if the black belly are fry since the other creamsicle mollies do not have that belly. Lastly, the last picture... wondering if this is a pregnant female. The other fish all bite at her anal fin area?

Hard to tell with just one photo, but I do not see anything obviously wrong. Looks healthy from pics.

first photo (yellow tint on black molly fins) - this could just be genetics showing through as the fish ages. and since pet store fish are notorious for having mixed bloodlines i wouldn't be surprised if he changes colour even more. it's not fin rot, that much i know for sure.

last photo - definitely a pregnant female.
