What do Senorita Fish eat?

The senorita's diet can, in some ways, depend on size. Small ones of about five inches or less have been known to eat plankton and ostracods, which are more commonly referred to as seed shrimp. These shrimp can only reach about one millimeter in length and only get smaller. The larger of the senorita species have been known to pick food off of algae and other plants and fish. The senorita is what is known as a cleaner. This fish will clean others for food. Their digestive system can process parasites as well.

My main male sea monkey is carrying my main female but she is curled up and not moving i believe she might be dead why is he carrying her around?

I also raise artemia as an easy source of fish food. I get very happy when I see this because it means they are mating. In a few days time a dark blob will appear on the female. They may separate then or even later. The dark blob is a bag of eggs which hatch into baby sea monkeys.

Do craps eat fish food?

No, crabs do not eat fish food. Crabs are scavengers and omnivores that feed on a variety of things such as algae, detritus, and small invertebrates. It's important to provide crabs with a balanced diet that includes fresh vegetables, fruits, and high-quality crab food pellets.

What type of food does a clown fish eat?

Clownfish primarily feed on algae, plankton, small crustaceans, and zooplankton in the wild. In captivity, they can be fed a diet of meaty foods such as mysis shrimp, brine shrimp, and commercial fish flakes or pellets.

What kinds of fish can tolarate water temps as low as 68 degrees?

Some fish that can tolerate water temperatures as low as 68 degrees Fahrenheit include trout, catfish, goldfish, and koi. These species are more cold-tolerant and can thrive in cooler water conditions compared to tropical fish species. It is important to still monitor and maintain stable water temperatures to ensure the health and well-being of the fish.

What negative effects do humans have on the clownfish and its environment?

The negative effects that humans have on the clownfish and its environment is the increased supply of carbon dioxide. Increased carbon dioxide causes the clownfish to lose the sense of smell and swim towards the predators.

How do fish see in dirty water?

Fish have specialized eyes with a high number of rod cells, which make them very sensitive to low light conditions. This allows them to see in murky or dirty water where visibility is reduced. They also have tapetum lucidum, a layer of reflective cells behind the retina that helps amplify light, improving their vision in low-light environments.

Can fish live in a two liter bottle?

No, a two liter bottle is too small to support fish. Fish need a certain amount of water volume, oxygen, and space to swim and thrive. It is not a suitable environment for fish to live in such a confined space.

Do tropical fish need salt water?

Not all tropical fish need saltwater. Some tropical fish, like freshwater species, live in rivers, lakes, and other non-saltwater environments. It's important to research the specific needs of the fish species you want to keep to ensure they are in the appropriate environment.

How do you tan fish skin?

In researching the topic of tanning fish skin. I have noted that the tanning of fishskin is not much different from the tanning of most other leathers. Remove the fat, meat, and scales. Then treat with a curing substance. One company uses plant based curing agents, though the process is kept a secret. A full compilation of various fish skin specific tanning methods should be established here.

Taken from http://poorbuthappy.com/yourthing/post/rare-information-on-tanning-fish-skinsobstruse---by-eskimo-woman/ :

Traditional Eskimo Fish Tanning Method

Urine tanning chemistry
Within the leather trade, urine has been used for dehairing skins, for
tanning skins and for washing skins.
Urine contains formic acid and urinase, and uric acid, among other things.
These acids have a preservative effect on the skin.
When urine is left to stand ammonia is formed, which is a strong base. If
a hide sits in urine for some time, the basic environment will begin to
have a dehairing effect.
The ammonia influences the skin by splitting the naturally occurring fats,
to form glycerol and free fatty acids. These free fatty acids can
penetrate the hide and react with the fibers of the dermis; the skin is
tanned. When ammonia is used as a cleaning liquid, it is it's saponifying
properties that are being exploited.

I have made a few tries at urine tanning of fish skin. The recipes I
started with come from Rita Pitka Blumenstein, who lives on Nelson Island
in southwestern Alaska. She relates the following:

"Fishskins were used for mukluks, mittens, water carriers, and
raincoats....The king salmon is used for boots, heavy-duty boots. Only
female silver salmon is used for hats for girls. And the pike skin is for
water jugs. The trout is for bags....
"You take the skin off and soak it in the water, and then you scrape it
with a sea shell. Some fish you have to scale; some fish you don't. Like
pike and white fish, you've got to scale it, you soak it in urine. The
urine has to come from a young boy baby before weaning. It doesn't contain
any chemicals, just momma's milk. For thicker skins, you have to use the
urine from an older boy, around the time his voice changes.
"[The skin soaks in the urine] sometimes half a day, sometimes overnight.
The longer you soak it, the softer it gets. Then my mother used to
use[Fells] Naphtha soap, and she sudsed it in the water and then cooled
off the water and then put the skin in it. Then she puts aspen shavings
in the water and cools it off, then you rinse it in clear water and wring
it out. My mother used a towel to absorb the water. I asked her one time
in camp, 'What did you use when you didn't have cloth?' She said they used
dried moss. And then you put it on a smooth board, stick it there, the
inside facing in. Then when it dries, it will just peel off itself. You
store it away, and when you are ready to use it, you wet the shavings that
you saved, and you pad them onto the fishskin on the outer side. Then you
roll it and leave it until it dries. Then you shake it off." [Hickman
1988: 19ff.]

I have started from this recipe but have used woman's urine for 10-12
hours and then rinsed the skins, washed them in water with soap, laid them
in a willow bark bath 10-12 hours, greased them with, for example, train
oil, dried them and softened them.

How does an air bladder help a fish?

The air bladder enables 'those fish that have them' to achieve a neutral bouyance, that is they can remain motionless in one place, or they can sink or rise however they please. Fish that don't have bladders 'such as sharks' are committed to either sink or swim they don't have the added agility or added ease that comes with a bladder.
Definition: Air bladder, also known as the swim bladder, is a large, thin-walled sac that may function as a buoyant float, a sound producer and receptor, and a respiratory organ. Located in the dorsal portion of the body cavity, the swim bladder allows the fish to move up and down through the water. When gas is added by diffusion through the blood vessels in the bladder walls, the fish becomes less dense overall, allowing it to rise. When gas is removed the fish becomes more dense, thus allowing the fish to descend in the water. The swim bladder produces sound by vibrating; these sounds are probably used in courtship. The organ also amplifies water-borne sounds and thus is an aid to hearing. In most fish the swim bladder has no connection to the digestive tract, but in some, such as the lungfish, there is a connecting tube leading to the pharynx, indicating that the organ may aid in respiration. Also Known As: Swim bladder http://freshaquarium.about.com/od/termsandtables/g/airbladder.htm

What fish is Saira?

Sauries or Sairas are fish which live in tropical and temperate waters. These fish often jump while swimming near the surface, skimming the water. The jaws of sauries are beak-like, ranging from long, slender beaks to relatively short ones with lower jaw only slightly elongated. The mouth openings of sauries, however, are relatively small and the jaws are weakly toothed. A row of small finlets behind the dorsal and anal fins is also a feature of sauries. An unusual feature of these fish is that they lack swim bladders. Sauries grow to a maximum length of about 46 cm. They are harvested commercially as a food fish. Sauries first appear in the fossil record in the upper Tertiary. Pacific sauries are consumed often in Japanese and Korean cuisine. The fish is usually grilled.

When do fish eat most?

What is a coelacanth?

The coelacanth is a fish which was believed to have been extinct since the Cretaceous period. However, in 1938 a curator of a museum found a coelacanth in a catch of fish of a trawler off the coast of South Africa. Since then, they have been noted to appear in Comoros, Mozambique, Tanzania, Madagascar, and even in Indonesia. The fish is blue with silver markings and grows to over six and a half feet long. Its population is estimated to be at a number of around 500

The fish was discovered (found) by the crew of the trawler 'Nerine", not by the curator, Marjorie Courtenay-Latimer, of the East London Museum - she made sure it was saved for science! Coelacanths are also found in South Africa and Kenya and it is steel blue/grey with white to pale pink spots and blotches in patterns unique to the individual. The population is unknown - the estimate of 500 or less was guesswork following surveys in the Comoro Islands. It is quite clear that, although nowhere abundant, the coelacanth is widely distributes throughout the western Indian Ocean.

When should the light over the fish tank be on?

You should be aiming for between 8 and 12 hours. about the same time as the sun is up. this helps with the natural environment of the tank, the plants will grow nicely, there wont be loads of algae everywhere, and your fish will behave more naturally.

this can obviously be adjusted to suit when you will be looking at the tank, after all your paying for it :P. I have mine on around 11am-9pm because this is when im most likely to be home!

too light can lead to an algae bloom and make your tank go green, if this happens don't leave your tank on for so long. it might also help to keep natural sun light off of the tank.
