live bearling platties
 
This is the first live bearig fish I have had in any aqurium for years, and I noticed this AM that there was 1 (surprizingly large) orange platty hiding in plants near the bottom. The female is still very large and has a gray coloration in the belly.

How long does it usually take for female to give birth to all of the fry and how many should I expect? The newly born fish appears to be feeding on very small particles of ground flake food I prefared. However I have a couple of large gold fish in the tank that keep the bottom of the tank clean and has attempted to catch the small fry a couple of times. What else should I be feeding them and do the even stand a chance for survival among the other platties and gold fish. Plenty of cover on the bottom where the fry now stays after the first gold fish attack.;-)

thanks

We don't think of goldfish as predatory fish, but in this case it would be a miracle for any of these fry to survive their parents, let alone the goldfish. Not only would I house the platies separately from the goldfish, I would house the fry separately if you intend on raising them.

I love goldfish, but they really are unsuited to aquarium life. Small breeds like pearlscales can perhaps be kept in tanks of 40-55 gallons, but standard goldfish top out at 12" or more and will eventually need tanks in the neighborhood of 150-200 gallons. But a pond is a better option. . .

Thanks for the advice. I know the Goldfish will have to go sooner or later, as you are correct, they do tend to grow in a 39 gal tank, plus they can raise the nitrate levels.

What really puzzles me is that the female has is still huge in size and the one original fish has found a very good hiding place and is feeding well on ground flakes and brine shrimp. Since I really have no interest in raising the fry, I just hope the little guy makes it.;-)

What I can't really figure out is why the female has not given birth to any additional fry. I've been told it could take in excess of a week, or more likely if any fry have been born, they have been eaten. And yes, Goldfish will eat small fry. To be honest, they seem eat just about anything.:lol: Great bottom cleaners. I've only kept Chiclids in the past. First live bearer for me.

thanks,
Ford

I had some pregnant swords earlier this summer they never came to term. I believe the heatwave we had might have caused the pregnacy to terminate. . .most livebears like water temperatures closer to 72 than mid-eighties!

I have since gotten airconditioning units for myself and for all the creatures living under my roof.

Were you referring to the length of gestation or the amount of time for delivery of a brood? I know gestation is temperature dependent but takes about a month. As for delivery, I would be surprised if it takes longer than a 24 hour period. Perhaps someone else can shed light on this.

Glad to hear at least YOU got some AC. This heat has been brutal in SW MO. I still have the 1 fish remaining after 5 days or so and it is feeding well and seems to have grown a bit. It would appear at this time that any others would have born and simply did not find cover in time. I have another female that appears to about ready. Don't really want any more anyway, but hope this one little guy will make it.

I am just getting back into swords after about 42 years. They were the first fish I really wanted to keep as a 6th grader. Specifically, the Red Velvet strain. My mom bought me my first aquarium and I have been penniless-- I mean-- I have been an aquarium fanatic ever since!

As a youngster, I never kept them in a tank larger than a twenty, but they really need a good long tank to swim as they were intended! Especially the males. I have a rag-tag mixture of "survivors" from the assorted swordtail tank at the local PetSuppliesPlus. I am just hoping to "learn their language" so to speak, so that I can confidently invest in some wild-type Montezumas, which are what I really prefer at this point. I call this a training exercise!

Three of my four females seem to be pregnant. Time to set up a maternity tank. Again. . .
