I just recently set up a 29 gallon fish tank with my boyfriend. We bought our fish at Petco a little over a week ago. We picked out 3 Mollies, 2 Swordtails(male & female), and 3 platies (I think :P ) anyways, my boyfriend wanted the "funny looking Molly" that was in the tank. It was the only one who looked like it does so we got it. Only to bring it home and start wondering if maybe the "funny looking Molly" is pregnant. I don't know how to tell if it's a male or a female, nor do I know how to tell if it's pregnant or just deformed. Our other two Mollies both died, but this one is doing quite well so far. I know that this one is a lot chubbier than the other two, the others looked like typical fish, slender and not bulging in odd places...but this one looks like some alien-fish.
So, I've come here to find an answer. I took some pictures of her/him so you guys can see for yourself and not just imagine what this fish looks like from my terrible description above.
The last picture is kind of confusing, but probably one of the best I have.
As you can see, our aquarium is still bare. We had these seeds that we planted that we hoped would have bloomed by now since they said only 15 days but no such luck. We're going back later to return the 2 dead fish and to get some more plants and stuff. I read somewhere that you should have a lot of plants so the pregnant one will give birth or something. Is this true?
Anyone have any suggestions on what I should do? Is it pregnant? Should I go buy a net to put the fry in? I have no clue what to do! Help would be lovely!!! How do I know when she's going to give birth if she's pregnant?
