Is my guppy pregnant? (Sorry for the bad photo)?

One can see why the question might arise. She is pretty thin and the other female guppy in the image is clearly more pregnant and possibly more healthy than she is.

A counter set of questions for you might include have you had her for a month? Have you found some gray guppy fry in the tank recently – indicating that she may have dropped them and then looks much thinner. Was she moved abruptly from one tank to another without gradually adjusting her to the new quarters. It is rare, but sometimes female livebearers will prematurely drop fry in such circumstances and sometimes (rarely) even be damaged enough that she is unable to produce young any more.

However, if she is a female guppy, nearing an inch in length, and has been with males in the wholesaler's or the pet shop or your aquarium, then the odds are overwhelming that she is pregnant. So many creatures eat baby and adult guppies, that in order to survive in the wild, they must do all they can to reproduce quickly and often.

As the young in her grow she should naturally become more robust. I would worry if they didn't grow, but there isn't much one can do for her beyond the usually good care.. As female guppies get to their last week of pregnancy, try to never move them (unless maybe you can gently herd her into a soap-less jar of water in the tank and release her in the new tank with very similar water) so they don't abort the fry.

Please never put her in a plastic breeding trap (also nicknames those little boxes of death.) A breeding net can be used, but where can the fry be raised up?

If you only have had her for a few days, wait a week or two, feeding her well and doing your weekly partial water changes (after gravel vacuuming fecal dirt out of there) and replace 25-50% if the water with treated stuff of the same temperature).

On the average, female guppies may carry enough sperm and developing eggs to have six batches of young. If kept in the 77-78 F range those batches will arrive very close to every 28 days, even if she doesn't mate again in that time period.

(In junior high I started with 1 very pregnant female in a well planted 10-gallon tank. A year later there were over 200 guppies in there and I was busy giving away guppies to neighborhood kids.)

As an aquarium gets over crowded, there will be some cannibalism. Your tank doesn't look too crowded, so if there are hiding places (often plastic plants or hornwort & Vallesnaria) & tank mates are well fed, there should be some fry around. If they are always chasing and eating fry, that is disconcerting but even in the wild some taking of fry may prevent crowding and disease out breaks.

You may have seen other young females begin to show that gravid spot like she has. Often that is dark spot by the tail. That lighter guppy female behind her has a much lighter gravid spot. In the next couple or slightly more weeks. if she is healthy, she should show the same pattern.

If you guppies are dropping fry, as you may know, fry can be fed crushed flake food or newly hatched bbs (baby brine shrimp). Try not to overfeed the bbs. Adults also will greedily take them too. If you feed a little defrosted frozen bbs, feed in a gravel-less tank, maybe with some small ramshorn snails to clean up. Siphon dead bbs and other uneaten food out to avoid epidemics

If you don't want to get into selective breeding of guppies, that is alright. Just enjoy them. If they are randomly breeding, over the years they may not grow so large or may not have the same colors earlier generations had,

Hope your female guppy thrives. And have fun!

lol okay I didn't think so. She's in a tank with four other females and two males so I was just curious. She has the biggest stomach out of all of them, and she's the largest, too.

No it's not..

i don't think so.

NO
