Pregnant Fish?

Question

1. Can you tell if a fish is pregnant and if you can how?
2. What is the gestation period?

1. If i didn't know the definition of gestation, I would not have been able to include that word properly in my question.

And, LMAO!! Tiny Condom!!!!!

Well, I have 2 femal swordtails that have swollen bellies and I have another black and white spotted fish that looks the same. I forget what kind of fish the black and white ones are, but they are just about the same size as the swordtails.

Answer 1

Be careful - your fish may not be pregnant, but they may have a parasite known as "Bloat".

Here are the ways to treat the Bloat parasite...

To treat Bloat, the plan of attack is:
Metronidazole and water changes, water changes, water changes!!

1. Remove carbon/resins from filter.
2. Perform a 30-50% water change (reduces free-floating bacteria population)
3. Add salt (teaspoon to a tablespoon per gallon) to aid the fish's osmotic regulation processes.
4. Treat with 250mg/20gallons of Metronidazole (Flagyl)
5. Leave for 3 days and do not feed.
6. After 3 days, perform another large water change.
7. Replace the salt.
8. Add full dosage of Metronidazole.
9. Wait another 3 days. During this phase, the bloat should be decreasing in appearance. In large fish, the water may take on an ammonia odor from the high volume of urea the fish should now be producing due to reducing the bloat and recovering renal activity.
10. 3rd day, another water change. Also, replace the salt and redose the metronidazole (full dose). If the fish looks to be well on the road to recovery you can offer a small feeding each day.
11. Another water change. No meds but, I'd recommend the salt. You should be clear now.

This is the treatment I use on my africans, puffers, and my lungfishes/polypteridae. Knock on wood that it's worked every single time

Hope this helps.

Most fish don't get pregnant, and instead lay eggs. Swordtails, platty, guppy, and molly do give birth to live young. (These fish are related and often called the livebearers.) Your other fish sound like Dalmatian molly. Gestation is generally a month, but can vary a bit. With livebearers you'll notice a swelled belly, and a black spot(s) on the belly of lighter color fish.

Generally the female will start hanging out in a corner, or near the bottom for a few days before she gives birth. If you are trying to keep the fry alive. This is the time to move her into a breeders net.
(Personally my tank is full so I just let the other fish eat them.) Unlike most fry these guys are "relatively big" and will eat crushed flakes, or brineshrimp. Note that live or frozen food can carry disease. Freeze dried is sterile, and easy to keep.

PS- A good food for expecting livebearers is freeze-dried brine shrimp. It's also good for the fry. Just remember live bearers are omnivores, and require a lot of vegs in their diet. An ideal mix would be an algae flake, and brine shrimp on aternating days.

PPS- All live bearer can take lerge amounts of salt. Molly in fact can live in salt water if the change is slow. If you just have molly, swords and plan on not have any other type of fish add 1 teaspoon of salt per gallon. Disolve in tank water 1st, and put no more that 1 per 5 gallons a day. If you have or will have other types of fish put it 1 teaspoon of salt per 5 gallons. Table salt is good as baby fish need their iodine, and table has only trace amount any way.

Answer 3

Well in livebearers: guppys, mollies, swordtails, and platys, they will be swollen and you can see some dark matter in the belly area if the fish is light colored. I remember mine having babies in about a month or less from the time I could tell they were pregnant. They usually start staying in the corner of the tank when they are ready to give birth. The livebearer fish (as their name indicates) dont lay eggs. Make sure they are separated from the other fish in the tank or they will get eaten

Answer 4

do you know the sex of the black and white one? Hint: the dorsal fin(on the belly) will be straight on a male and faned out on a girl. Their bellies will get larger if they are pregnant thats really the only way to tell. I'm not sure on the gestation period but it's around a month.

Answer 5

1. It can be not viable to "prove" evolution of the earth considering none of us were there to take pix and document the "event". It will by no means be viable to prove it. It'll continually be a thought. 2. There's no solution to "prove" that all fish as soon as breathed water handiest, in no way walked on land and had been on no account pregnant, when you consider that that we nonetheless shouldn't have catalogued the whole animal/fish population of the earth as good as studied the historical past of each one. 3. You must get beyond trying to "show" evolution to any person. If they don't be given the speculation of evolution then they mainly in no way will. What would persuade me of evolution? Seeing it for myself. It can be the same requirement you provide of God, right? EDIT: "i do not require for God to get down from his cloud and knock on my door. I require from God to be the logical clarification... Which he isn't." but truely, you do require Him to do that very factor as a way to furnish proof. After all, some thing else would be a thought. "Evolution is the logical rationalization." Of path it is, it's the best clarification we've, I by no means stated it wasn't. However you requested what would convince us it is genuine and anything else instead of seeing it with our possess eyes is best thought or rationalization, no longer proof. "Viruses evolve always and turn into new species, whether or not it's carried out in a lab (biochemical weapons) or naturally happens (avian flu, aids, etc.)" No, they don't evolve, they mutate. This is a component of the problem, the best way we use our words ... Mutation isn't evolution.

Answer 6

one million. It's now not feasible to "turn out" evolution of the earth due to the fact that none people have been there to take portraits and record the "occasion". It will NEVER be feasible to turn out it. It will consistently be a thought. two. There is not any strategy to "turn out" that ALL fish as soon as breathed water best, by no means walked on land and have been by no means pregnant, when you consider that that we nonetheless shouldn't have catalogued the complete animal/fish populace of the earth as good as studied the historical past of each and every one. three. You have got to get past looking to "turn out" evolution to someone. If they don't be given the speculation of evolution then they customarily by no means will. What could persuade me of evolution? Seeing it for myself. It's the equal requirement you provide of God, proper? EDIT: "I do not require for God to get down from his cloud and knock on my door. I require from God to be the logical rationalization... which he is not." But honestly, you do require Him to do this very factor to be able to furnish evidence. After all, some thing else could be a thought. "Evolution is the logical rationalization." Of direction it's, it is the first-class rationalization we now have, I by no means stated it wasn't. But you requested what could persuade us it's real and some thing else rather then seeing it with our possess eyes is best thought or rationalization, now not evidence. "Viruses evolve at all times and grow to be new species, if it is performed in a lab (biochemical guns) or certainly happens (avian flu, aids, and so forth.)" No, they don't evolve, they mutate. This is side of the predicament, the best way we use our phrases ... mutation isn't evolution.

Answer 7

a million. that's not attainable to "coach" evolution of the earth because none human beings have been there to take pictures and checklist the "journey". it heavily isn't attainable to coach it. that's going to consistently be a theory. 2. there is not any thank you to "coach" that all and sundry fish as quickly as breathed water purely, in no way walked on land and weren't in any respect pregnant, once you evaluate that we nonetheless have not got catalogued the entire animal/fish inhabitants of the earth as properly as studied the background of all and sundry. 3. you are able to desire to get previous attempting to "coach" evolution to every physique. in the event that they do no longer settle for the assumption of evolution then they in all probability in no way will. What might convince me of evolution? Seeing it for myself. that's the comparable requirement you supply of God, precise? EDIT: "i do no longer require for God to get down from his cloud and knock on my door. I require from God to be the logical rationalization... which he's no longer." yet actually, you do require Him to try this very element so as to grant info. in spite of each and every thing, something could be a theory. "Evolution is the logical rationalization." of direction that's, that's the perfect rationalization we've, I in no way mentioned it wasn't. yet you asked what might convince us that's real and something different than seeing it with our very own eyes is barely theory or rationalization, no longer info. "Viruses evolve perpetually and turn into new species, no count if that's complete in a lab (biochemical weapons) or of course happens (avian flu, aids, etc.)" No, they do no longer evolve, they mutate. that's a ingredient of the undertaking, the way we use our words ... mutation isn't evolution.

Answer 8

many female fish have a 'gravid spot'
this is towards the end of thier belly and it can go really dark when they are pregnent this shows up particularly in tetras I believe

Answer 9

1. Yes, usually just looking at their belly
2. Depends on type of fish
