How long does a fish pregnant for?
by
Fish pregnancy can last anywhere from 3 weeks to 3.5 years depending on the species. Fish pregnancies usually last between 3 weeks and 10 months. This huge range is due to the differences between various fish species. Aquarium fish like goldfish or guppies are at the lower end of the spectrum.
How do you know when a fish is about to give birth?
To accommodate the developing eggs, the mother’s body expands, becoming deeper and broader. A few days before delivery, she develops a bulge below the gills, her outline becoming fairly square in this region, while the gravid spot has enlarged its area.
Is my fish pregnant or fat?
Carrying Eggs – One reason your fish may appear slightly bigger is because it is carrying eggs. If your fish is a female, is not overly fat, and is normal in most other regards, this is a very high possibility. Another indication is if your fish has an enlarged vent; this is where the eggs will come out.
This could be caused by a number of things, such as a swim bladder problem, constipation or an internal infection. ✔ Make sure that the water quality is pristine (test for ammonia and nitrite using King British 6 in 1 Water Test Strips), and the dissolved oxygen is high (by ensuring good aeration).

What does an overfed fish look like?
What happens if I overfeed my fish?
Some of the health problems associated with overfeeding include improper digestion, fatty liver and fin rot. Improper digestion leads to a contaminated tank because fish produce more waste than usual. Fatty liver is a hepatitis-like disease that mostly affects cichlids and other fish who are hearty eaters.
How often do you clean fish tank?
Depending on how many fish you have, and how messy they are, most tanks require cleaning about once every two weeks. Cleaning should involve: ✔ Siphoning the gravel to remove any debris and uneaten food, and changing about 10-15% of the water.
Is it OK to feed my fish every other day?
For the most part, feeding your fish once or twice a day is sufficient. Some hobbyists even fast their fish one or two days a week to allow them to clear their digestive systems. Larger, more sedentary fish can go longer between meals than smaller, more active fish.
Can fish see in dark?
Fish living in the deep sea manage to navigate in complete darkness. It’s not strictly ‘seeing’ but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.
Malawi bloat is usually treated with metronidazole. If the fish is still feeding, metronidazole-dosed foods can be used. Alternatively, doses of up to 50 mg per gallon can be added to the water, though this tends to be much less effective.
Will fish dropsy go away on its own?
Dropsy is not easily cured. Treatment is geared toward correcting the underlying problem and providing supportive care to the sick fish. A broad spectrum antibiotic specifically formulated for gram-negative bacteria is recommended, like Mardel Maracyn® 2. Always follow directions for duration and dosage.
How long will a fish live with dropsy?
Most often a fish with dropsy dies. Perhaps not immediately, but within several months. Indeed, in instances where dropsy is caused by internal infections, the bloating will disappear for a time, only to return a bit later with a vengeance.
What does dropsy look like?
Swelling of the abdomen. Eyes that are beginning to swell and bulge. Scales that starting to point outward instead of lying flush with their body giving a “pinecone” appearance. A loss of color in their gills.
What does the start of dropsy look like?

How do you put down a fish?
Clove Oil (contains eugenol)
Clove oil is a sedative which at high doses, can be used to euthanase small fish. Unlike veterinary anaesthetics, clove oil is readily available from most chemists. Around 0.4ml of clove oil per litre of aquarium water is sufficient to cause death in exposed fish.
Out of all the “old-school” methods, this process seems most inhumane. The AVMA does not advocate freezing fish as an acceptable method of euthanasia; the only way they would approve of cooling would be to deep freeze an animal that is already under deep anesthesia.
Should I bury or flush my fish?
Worst of all, flushing a dead animal can be extremely harmful to local waterways, wildlife, and native fish species, especially as some sewage drains lead to rivers and oceans. When fish die, never flush them down the toilet or other drains – bury, cremate, or put them in the trash.
What does baking soda do to fish?
One of the safer chemical anesthetics that can be used in anesthetizing fish is sodium bicarbonate. It is also known as baking soda and when dissolved in water, it liberates carbon dioxide, which has an anesthetic effect on fish (Bowser 2001).
What does Coca Cola do to fish?
Diluting the oxygen concentration in water by adding carbon dioxide from soda makes extracting oxygen much more difficult, which can cause a fish to panic and try to escape.
What kills fish naturally?
The most common cause of natural fish kills is lack of oxygen in surface water. Lack of oxygen can asphyxiate most susceptible fish species within a few hours. Depletion of oxygen in water can result from natural processes and storm events are very often involved.
