Just got back from the pet store with 2 new swordtails. Carrot is a girl and very very pregnant. The same color as a carrot she is. Also got her a boyfriend who is mostly whitish with an orange stripe down his body. Kids named him Orange. Ok here is my question, Carrot is very pregnant and is in a net and Orange is swimming in the tank happily. He is very shy and i was wondering if i should worry about him being in there with black skirt tetras and head and tail light tetras since they are nippers and he does have that long sword. There are also a couple of guppies in there. I have to say i never realized how much bigger they are than guppies until i put them in the tank. She is twice the size of my guppy girls, should i be concerned about that? I know i should have done more research on them before i brought them home, but they were playing with me at the store so i had to get them. ) Any replies would be great thanks. Sandy
