sexually.

Asexual reproduction is really rare in multicellular organisms. Prokaryotes reproduce asexually, and are normally single-celled. Aphids can clone themsleves, and apparently turkeys can produce self fertilised eggs if they really need to. Fun fact of the day :)

Angelfish have small, thin bodies, that enable them to slip through thickets of plant growth and are able to squeeze into tiny cracks to escape from predators or other fighting angelfish.

Angel fish are freshwater fish that originate from the Amazon region of South America.
the angel fish has many type or kinds and can be found all over the world yet it tends to stay most commonly in the sunlight zone

Yes, well... when you buy it, it may already be pregnant, you never know. But if you want it pregnant after you get it, then it may be harder. They can if they are happy enough or are having hybrid fry.

Yes. Fish do have lips, I think. I'm sure of it. In fact I think that they have really big ones. Sometimes...

Yes, a black Molly is a breed of fish in the breed "Molly". They grow up to about two and three-fourths inches from head to tail. These fish are a community breed so you can mix them with other community fish. They come from Central America.

I have had Oscars for about 3 and a half years now and I have always kept my tank right around 80 degrees F. The temperature can safely range from 75-85 degrees F, but 79 is really where you wanna keep it.

Angelfish can survive on a basic diet of flake food. However, in order for your fish to grow big, beautiful, healthy, and fully develop, it is recommended to feed them live foods such as brine shrimp, bloodworms, etc. For more information, check in with your local pet stores or join a tropical fish forum.

These fish feed on guppies, smaller fish. They also eat plankton. A flaky substance called cichlid flakes and also they are on a special diet where they eat hatched Brine Shrimp and sometimes eat a substance called Angelfish flakes.

Freshwater Angelfish usually do typically well on flake, pellets and frozen blood worms. Saltwater Angel fish typically do well on marine flake, marine pellets and frozen mysis shrimp. A special species specific formula for Angels of both types can normally be found at your LFS.

crustaceans or small crabs or really anything crunchy because they have very strong teeth.

various flake food, bloodworms and the babies like baby brine shrimp

Depends where you get them from really, but theyre not expensive at all.

In pets at home, goldfish are on sale for 99p, in some other places they might be up to £2. The one that I've got, was £3.78. But it was a rare type, so it was probably more expenisve

If you mean the tanks as well, ideally you should get a tank at least 10 gallons, but if you are new to fish keeping, you can get starter tanks from places like pets at home for about £20, which are quite big and have a filter with it. Make sure you get an air pump as well though, alternatively, you can just drop a few oxygenating tablets in every few days

Yes, elevated levels of nitrate can negatively affect fish health. While fish can tolerate low concentrations of nitrate, high levels can lead to issues such as decreased oxygen levels in the water, which can stress fish and impair their ability to breathe. Additionally, excessive nitrate can contribute to algal blooms that deplete oxygen and produce toxins harmful to aquatic life. Therefore, maintaining balanced nitrate levels is crucial for a healthy aquatic ecosystem.

Oh, at least six-eight months, I think. Depending on how well fed they are. Convict fish are very good parents!

To Vent an Oscar you must first remove it from the tank and turn it over onto it's back so it is belly up. You must then examine the Vent.

The Vent is the opening between the anus and the anal fin. This is where the male fish release their sperm and the female fish release their eggs. This area is also known as the genital papilla.

The female's Vent will be larger than the males to accomadate the passing of the eggs.

Unless you have one of the opposite sex for comparrison it will be difficult to determine sex for the unexperienced hobbyist. It will also prove to be more difficult with younger fish rather than more mature fish.

For sexually monomorphic fish species (females and males look alike) Venting is the most accurate form of sex determination.

Signs of pregnancy are a large belly, a boxy-look from the front view, and a darker gravid spot, the spot, under the fish's tail. Near the day of delivery the gravid spot becomes darker and you can sometimes see eyes of the unborn fry as tiny black dots. Female guppies can drop fry every 4 weeks.

The angler fish usually live very deep in the sea so the fish need light for to find it way.it also help the fish to attract small fishes to eat.

i have a plec but i know someone who had loaches golden barb and a sharkfish and they were fine

You can keep other fish of a similar size and temperament with tetras. You may also keep smaller sized Veil Angels with them, although your best bet is to stay with fish that are also brackish in nature. The size of your tank is also very important with determining appropriate tank mates.

Between 12 and 18 inches--or 30cm to 45cm if you live in a metric country. They will do this no matter the size of your aquarium, so don't listen to the guy at the pet store who will tell you they will stop growing in a too-small aquarium.

Dalmatian Molly fry are very tiny and hide in plants for cover. They are clear when they are young but gradually, they grow black spots.

a total of 100 to more than 1,200 eggs are laid, depending on the size and health of the female fish.

Guppies are pretty hardy fish, they can easily survive without a filter. What most animal lovers will argue is that even though they can survive, it is abuse to the fish and you need your fish to "thrive".

Fist off, why do fish need a filter?
All a filter really does is clean the water and another thing that I will get to, therefore if you clean the bowl on a weekly basis than you have the cleanliness part covered. Unlike gold fish which have a huge amount a wast, the guppy is average.
For the second reason which to have a filter: all it does, compared to a bowl, is disturb the water surface which allows more oxygen into the water. Thus, the more surface area in a unfiltered tank the less needed is a filter. For example, if there was a tube that was 5ft. high and just 1in x 1in long, than the fish would probably die after using up all the oxygen that was already in the water, if there was a tube that was just an 1in high but was 5ft. long than there would be greater surface area and a filter would not be needed for most any fish (even though no fish should live in such a place). So, for the oxygen thing, you could even have just an air pump and do water changes often and be set (even though a filter is more preferable).
Now, should a guppy live in a bowl or a tank without a filter? I know from my own personal experience that they most certainly can survive. But that still isn't thriving... ...there is a good medium for the two...

Though my experiments on the subject at hand, I have found that guppies (this is the most extreme) can live in just a cup of water, and did water changes every (up to) three weeks and still live! To me, though, this is cruel. Now, some people make super houses for there dogs (thriving); yet the same dog can still live in an apartment (surviving). You really need to be the judge. I would say a three gallon tank, one that does not need to have filter would be most reasonable for your money and for a number of guppies to live unstressed.







Almost all freshwater fish, with the exception of bettas, like aerated water that is clean and constantly moving. I kept eight guppies alive in a salsa jar for two years when I was about nine, but I changed the water twice a week, every week, and I didn't overfeed my fish. I also aerated the water twice a day with an eyedropper.
If you must keep fish without a filtration and aeration system for any long period of time, scoop up water with a cup twice a day and drop it back into the container from a height to dissolve oxygen in the water. Change at least half the water two or three times a week. I always changed all the water and rinsed the gravel, and the only plant I kept was floating. Most fish will die from the stress of a total water change, and the hardy guppy is one of few species that can tolerate it.
You will also need a long, flexible plastic tube. Keep the fish container high up, and once every few days, siphon out waste. Place the tip of the tubing into the water, get down as low as you can without moving the tip of the tube out of the water, and suck on the other end. As soon as the water starts to draw, drop the end into a bucket. Use the suction created by the siphoning to remove fish droppings, uneaten food etc. Then top up the water.
Without a filter, without aerating the water at all, I would say you've got about three days before the guppy dies, and it would be so distressed anyway that that's an appauling welfare issue. The only fish that I have in non-aerated tanks are fry, and I do those three to five times a day to keep them going. The only reason I keep them like this is because they'd be eaten in the main tank with the adults and I can't set up fifteen fish tanks in my little house.

Crabs use their powerful claws to access their food, via prising or pulling. They then use their pincers to snip the food up into small portions, before transferring it to their mouths human-fashion.

there is no definite way to tell goldish appart. But when the water temperatures are warmer, if there is a male and a female fish in the tank, the male fish will chase the female fish around the tank, nudging at her belly, to try and make her release eggs. So if you ever see a fish chasing another fish, the fish doing the chasing is a boy and the fish swimming away is the girl.
