Do fish look after their young?
They do if they can't get out of the aquarium. In the wild, most fish don't have that option since many fish are like salmon in that once they've spawned (females laying their eggs, males fertilizing the eggs), the adults die and aren't around by the time the eggs start to hatch.
Some fish breed several times in their lives but never see the offspring, but some others lay eggs, breed, and one or more adults will stay to defend the eggs and young for a time even after hatching.
The true answer to your question is...
It depends on what kind of fish you are talking/asking about, and whether they are in a natural body of water, or an aquarium. Some fish will even eat their own young if they're still in the area when their eggs start hatching. Guppies are one type that will do this.
Why is the angler-fish threatened by humans?
The Angler fish has a fleshy growth protrudes from its head and ends near its mouth. This looks like a worm on a hook and fish seeing this thinks that there is food available and moves in to take it. When they do the Angler fish strikes
All fish have bones. Some are so small you can eat them (like sardines or anchovies). Seafood that doesn't have bones are shell fish, octopus, squid, sea urchin, sea cucumber, and other invertebrates.
What should you do if your fish is not eating?
It is perfectly normal for a new fish not to eat for the first few days. In fact, you shouldn't even offer food until the fish has been in the aquarium for at least 24 hours. Since any uneaten food will just foul the water unless it is removed. If after 3-4 days the fish still will not accept food, start looking for signs of disease and have the water quality checked by an aquarium/pet store, specifically test for Ammonia and Nitrite. Other signs of disease in Goldfish include (but are not limited to) small white spots, red streaks in the fins, rapid gill movement/lethargic, red inflamed gills, cloudy eyes, damaged ("rotting") fins, or white/gray film on the body.
Also, if you put some garlic in (just a tiny tiny bit) it makes goldfish hungry. Check your fish's eyes as well he might have gone blind therefor he will not be able to see the food.
How many blue fish tuna are left in the world?
some seem to believe not that many for some reason and others believe 1 milllion just not found yet.
Is a 5 gallon tank big enough to breed betta fish in?
I think it should be 10-20 gallons.
You can breed Bettas in a tank as small as 5 gallons, however, if you use a 20 gallon long, you can leave the fry in the same tank until they need to be jarred.
How did the chameleon protect themselves?
I don't know. Look, if you were making a page for class in Rhiw-Syr-Dafydd Primary, then think of a better animal than this... thing! They have the ability to change color to match their surroundings.
Their fish food follows a particular colour scheme of red and orange and yellow and green and blue and indigo and violet.

Do salmon swim at night or day?
They swim in both, they start off life as alevins, then fry then parr. They grow to smolts, then they swim out to sea. Then they are called post-smolts. They travel (In europe) to the feeding grounds around iceland, where they may stay for one or more years. They return eventually, to the river that they were born in to lay eggs and start life over again. Sutterby, R. Greenhalgh, M. (2005) Atlantic Salmon an Illustrated Natural History.

What makes puffer fish puff up?
The Puffer Fish will puff up on a number of occasions. The most frequent is if it feels threatened or if a predator is attempting to eat the Puffer Fish. This method makes the Puffer Fish hard to swallow and does not look as appetizing to these predators.
A fish that can hide its pancake-shaped body in the sand or mud?
An octopus can hide its body in the sand or mud.
What kinds of fish are Jews allowed to eat?
To be kosher, a fish must have fins and scales (Leviticus ch.11). So for example salmon has both and is kosher. Some eels, however, are not because while they have scales they have no fins. The sanitary reason is that fish without fins tend to be bottom dwellers and bottom dwellers, like lobsters, clams and oysters, tend to live in shallower waters and feed on anything they can find -- and in ancient times shallow waters was where human waste washed into the sea....Need I say more?

Can a betta fish live in a 2 gallon bowl?
Bettas, like most other fish, like to swim around. A single betta needs a 5-10 gallon tank with a heater and filter for optimum health. Plants and caves make it more interesting for him and a couple of rasboras might work, depending on his aggressive tendencies. They can't be kept with other bettas, but do appreciate tank mates if they have room. The red ones tend to be more aggressive. If he is aggressive, he will not do well with other fish unless he's in at least a 30 gallon tank. People tend to think they don't live long, but if they have enough room, clean water, and consistent temperature, they will be much less stressed and can live for a lot longer than expected.
They can live in 2 gallons, but you can live in a bathroom if someone feeds you. It would probably shorten your life and certainly make it less healthy.
For a few months maybe...A year at the most. That is nothing compared to 5 years (how long bettas usually live for). A 5 gal tank with some ghost shrimp, a heater, filter and real plants would give a betta the best life ever :D
You COULD but I keep my betta, some ghost shrimp, and three Cory cats in a five gallon with lots of hiding places and short/medium/tall silk plants that the betta loves to "weave" through. I'm also purchasing a 2.5 gal for a single betta and some ghost shrimp though. I persoanlly think a betta will thrive in a five gal but can live on average of about 2 years in a 2 or 2.5 gal. You should do water changes twice a week because ammonia builds up fast in smaller tanks and make sure the betta won't snack on any ghost shrimp if you add some. I feed my betta baby betta pellets (he is small for his age) and the corys get flakes (soaked), while the betta snacks on some of the flakes but the corys get a lot of food...The shrimp just eat left overs and are great for that! So I would say go for it. You'll have lots more fun with something that you can decorate and add more fish too though, like a 5+ while if your money/space is limited, a 2 gal will work.

What a crowd! Corydoras need at least 30 gallons to live a healthy life. You are way overstocked with all those fish in such a small space. Again, like living in someone's bathroom. It can be done, but isn't fair. They're not criminals, so please stop treating then as if they are. This is bold because it comes naturally from your bold. I won't change it, but you might want to. It's not as if either of us is worth listening to while we yell. Corys are schooling fish and cannot school without enough room: at least a 30 long.
- 1. Salmon migrate up to 4,000 miles from the ocean to freshwater areas to spawn (or lay eggs). They also must swim against very strong ocean currents just to reach freshwater, and then swim upstream against the powerful flow of the river. Additionally, they must leap clear of the water to get above falls, and do all this while avoiding predators - who know they are there and want to catch and eat them. They do all this only to die only minutes after spawning.
- They are healthy fish.
- 2. They are the state fish of Alaska.

Yes, They are actially VERY good. I am sitting in Thailand right now on vacation, and I tried one for the first time today from a street vendor. These fish are excellent. They have a fairly firm meat on them with a mild flavor. Think texture like tuna with a flavor like snapper.
Are flying fish invertebrates?
Invertebrates are animals without a backbone. So no flying fish are NOT invertebrates.
Where in the worl does the Atlantic salmon live?
Atlantic salmon Make atremendous journey throughout their lives. They swim from little fresh water streams that they were born in into the north Atlantic ocean. They then swim all the way back again to the same little stream they were born in and spawn. At the end of their journey most of the salmon die either from exhaustion or from disease.
Cod , Salmon , Trout , Tuna , Sardines , Eel. to name a few
some more are herring, angler, worms, and dogs they might sound like some other animals you know, but you should try them. they're delicious!
To be kosher, a fish must have both fins and scales - hence no sharks, rays or cetaceans (which were believed to be fish in the times when kashrut laws were first developed). Pollock have both and are as a result kosher.
