How do you know if a red devil fish is male or female?
When the Red Devil Cichlid (Amphilophus labiatum (in USA) and A.citrinellum (in Australia)) reach maturity, in both species, the males develop a hump on their forehead. I do hope you realise that these fish grow up to 18 inches long and therefore require a very large tank.
What gas is a swim bladder filled with?
it is filled with all kinds of air that can be found underwater.....
Its 2010 now, so 3000 years ago would be 1023 B.C.
because it is said that there was 33 years between
B.C. and A.D.
I wish I knew as I am trying to research it at this moment in time and am struggling at finding a answer for science!

Do the dots on the sides of a Goldfish tell you its gender?
No. Those dots are called the Lateral Line. It is a series of sensors that lets goldfish feel changes in water currents. The Lateral Line lets schools of small fish stay together, even turning in the same direction almost simultaneously. Sometimes the fish can even sense the movement in the water that means a larger fish is sneaking up on them from behind!
Can we feed termites ( like Damp wood termites ) to the Aquarium fish?
You can try to feed them to those fish that usually are fed this sort of thing. Be sure you 'wash' them off first.
Does the eye of a fish have a nictitating membrane?
Some do, only they are called nictitating membranes, instead of eyelids.
Here's an answer from a friend of mine on another site:
Just to add to your confusion, but perhaps to resolve some other unclarity: Indeed, there are "fishes" (plural allowed due to the plurality of species) that have eyelids. As someone poited out, some sharks have nictitating membranes, while others do not and roll their eyes backwards to protect them instead. The essential problem of your question, however, is the word "fish". For biologists, fish are not a truly monophyletic group. This is the fancy way of saying the critters usually subsumed under the category "fish" are actually not really closely related to one another. A shark is about as closely related to a gold fish as we are to a frog. What has been referred to as "fish" is usually an aquatic animal with some form of torpedo-shaped body (certain variations permitted), gills and fins. But if you take a closer look at the anatomy and genes of these animals, huge discrepancies and differences are revealed.
Eyelids in land animals largely serve the purpose of keeping the eye moist, a function not required in aquatic animals. But they also protect the eye from mechanical imapcts, and this certainly is a problem for all animals, aquatic or terrestrial, especially when they are predators. Take the shark example again: sharks often prey on large animals that in case of a struggle could injure the shark's eye. To protect itself, the shark with a nictitating membrane will close the membrane to cover the eye. Sharks lacking the membrane will roll back their eyes and thus protect their eyes with their sclera that contains cartelage. (If you ever have the chance to hold an eye ball of a shark, you will notice how stable it is and how you'd have a really, really hard time to bend it.) Elasmobranchs (sharks, skates, and rays) have eye lids (an upper and lower one) which cannot, however, cover the entire eye. The nictitating membrane can be viewed as a third eyelid that does the job.
In other "fishes," such as teleost, eyes are essentially lidless. Instead, here the eyes are covered with a translucent skin called the conunctiva.
They eat planktonic crustaceans and small schooling fishes.
What type of body covering do chondrichthyes have?
Chrondrichthyes have tooth like scales called denticles or placoid scales. Denticles provide two functions, protection, and in most cases streamlining. Mucous glands exist in some species as well.
How does a rainbow fish reproduce?
The rainbowfishes are belonging to the Australian region.Their beautiful coloration, active and moderate size in conjunction with Their frequently easy maintenance makes them ideal for our home aquariums.Since the majority is schooling fish, they will need free swimming space in home aquarium, they will also appreciate rocks and roots in their tank.The Melanotaeniidae are the rainbowfishes proper. The family consists of 6 genera and more then 55 species.They can be found on northern and eastern Australia and on New Guinea.In this family males are usually more colorful. Rainbow fish spawning eggs.

If you have fish in an aquarium and some of the fishes tails are ragged or being eaten by other fish it means that that fish is being bullied by the others. Try asking a pet shop staff member for advise, but probably separate that fish from the others.
