Smile Platies Pregnant?

Hello,

I am relatively new to the hobby and have a 10 gallon tank with 3 red wag platies and 2 sunset platies. I recently added the sunsets and in my opinion they appear to be getting larger. However; I've also been having an issue sexing all of these platies. I know that the male anal fin is pointier and can definately identify a couple of males in the tank, but there are others that sometimes the anal fin looks pointy and others it is relaxed and looks more fan like. Are these males or females and are there any other way to identify the difference? Also if these two platies are pregnant are there places where I can sell them, or what do I do to get rid of them(of course in a humane way) as the tank is way too small to handle the fry. Thank you for all of your input! (I have no pictures, and no way to upload pictures)

Hello and welcome to TFK To answer your first question first on sexing. Some of my females at times will draw up their anal fin, as you have noted when it is relaxed it is fan shaped, definitly females. Around 3 to 4 months of age is when you are able to start to distinguish between males and females. Most of the platys that you buy at the store have already reached sexual maturity, although sometimes you can get them younger than that, and some people have had what they thought was a female become a male. Was always a male but had finally matured.

For your second question, you can check with your local fish stores and pet stores to see if they will buy fish or will even take them. The larger chain stores like Pet Smart will not usually, but check around with the smaller ones. You can also give them away to friends, if you have anyone who is interested, although this option will only last for so long. If you leave the fry in with the adult fish most of them will likely be eaten by the other fish. In my community tank any fry that are dropped in there don't make it long, even with the hiding spots that are available. Although I also have angels and corys in this tank which makes their chances of being able to survive pretty slim. If you are interested in raising the fry there are a couple of options, you can either use a net breeder that hangs in the aquarium and place some of the fry into it. You will need to keep them in there until they are big enough that they don't fit into the mouths of the other fish. Or you can always set up another 10 gallon to raise the fry in. It all depends on what you want to do.

Thank you for your input BarbH. Now I just have to figure out if there actually pregnant or not. I havent seen a gravid spot or anything, but they appear to be very large. Larger than what they were when I bought them. Perhaps its just me! :)

Most of the time when you buy female livebearers they will be pregnant, unless they have been kept seperate from males. Female livebearers can also store a males sperm for up to six months. On the platys depending on how dark their coloring is you may not see a gravid spot. On my black red tail vari. I do not see a gravid spot on them. But they will get larger in the abdomen and eventually they will start to square off. They will get so big that it will look like they are ready to explode. Just took some pictures of one of my pregnant females and one who is not showing to see comparison. I am guessing that the pregnant one will probably be ready to drop fry in the next week or so, although I am not good yet at judging when. Will try to get those posted here shortly, takes a little bit for computer to load pictures.

First picture is of female platy that is ready to drop fry soon, second picture is of platy that has already dropped fry, and last picture is a comparison of the two, the one that has already dropped is to the right. Pictures are the best, glass was a bit dirty and everyone was fairly active. But thi will help to give a bit of a reference.

I would have to say there is a good chance they are both pregnant then. There definately rounded like that and not thin as in the second picture. I see your from Michigan, are there any pet stores that take fry that your aware of. From Kzoo/BC area. I'm really at a loss if I can't find a pet store to take them, I don't want to allow the other fish in the tank to eat them.

My local Pet supplies plus and Pet Provisions will take fish from local breeders. I am not very familiar with the Kzoo/BC area. I am located almost between Lansing and Detroit off of 96. I would check those type of stores in the area or any fish stores around you. Those who will take them it will depend on how much room they have at the time. In my opinion best to find out when they place their orders and when you have fish you want to bring in, talk to them before they place thier weekly orders. Better chance then off them having room, or even needing them. Also find out at what size they are willing to take them for selling. Platy fry are slow growers so plan on raising the fry for at least a few months probably. Right now I have about 40 fry that I am growing out that came from one female that dropped 3 weeks ago. They have grown quite a bit but still very small. Frequent feedings and water changes will help, also from what I have read about others experiences baby brine shrimp can help also when they are small, but not neccessary.

Is raising the fry in a 10 gallon tank sufficient? Also when you set up a tank for fry does it need gravel and decor or do you just raise them with just water.

Depending on how many fry that you have, a 10 gallon will probably be okay. I am actually going to be setting up a 20 gal to continue to grow mine out, with 40 fry in one drop the 10 gal is working for now, but a larger tank in my opinion would be better. For set up I would keep it simple, bare bottom and decor is really not needed. I do have some plants floating in the 10 gal with my fry, but other than that the tank is bare. A bare bottom will let you be able to keep the tank clean, which is important for the growing fry. Also with little decor it will also help in making cleaning easier. I try to do water changes every couple of days at least, although daily changes would be better. The bottom does tend to get dirty fairly quick. For a grow out set up I would do a bare bottom, some floating plants, heater, and for filter I would use a sponge filter. The HOB filters can suck the fry up in the intake if there is nothing covering it, and in my opinion it causes too much current in the water for the fry.

How long would you say the pregnant platy pictured has left until she births?
