Aquarium Fish Species

There is no species of dolphin called "Blue Dolphin", despite the book "Island of the Blue Dolphins." but there are blue whales

well they keep breeding while there is a female in the tank and the water conditions are right. you should get at least 1 male and 3 or 4 females or 2 males and 3 or 4 females. you want to get more females than males so the males dont harrass the female. the female can often give birth 3 to 6 times without having to breed again. I remember when my male and this one female bred together and soon after her second birth the male died and she gave birth about 4 more times.then a few months her last birth she dissapeared. Anyway its about 2-3 weeks between births so if your platy is pregnant I hope this helps and good luck!!!!

Yes I'm fairly certain. I have 1cardinal and 4 neons and they all swim together...

yes they can

no chance they find their own companion and breed this can be done only scientifically at laboratory levels

A reasonably well grown angelfish used to be over 6 inches high. Many of those "fancy types" available now are so badly inbred that they are lucky to reach 4 or 5 inches high.

between 3 mm and 6 mm

Fish of the family Poecilidae, yes that includes Mollies, don't have the mouths to cause serious damage to each other, or other fish. They can peck at each other, but the worst that could happen is a guppy with a small rip in the tail. They can, however, eat fry. Fish of the family Poecilidae will spend more time showing off and "pushing" each other with their tails than actually fighting.

There are several cichlids that come under the general name of Mbuna. I believe they are all fairly large fish growing to around 7 or 8 inches . A large tank is required as is very alkaline, hard water.

From birth. All you need to do is grind up normal livebearer food to a size small enough for the fry to eat. As the fry get bigger so the food they eat can increase in size too.

There are many similarities between angelfish and goldfish- to name one angelfish and fancy goldfish (especially the oranda) both have several long delicate fins.

yes they do

Sawfish, tarpon, and sharks.

Tetra is a type of a freshwater fish, usually colorful, and is native to America and Africa, and they are also popular in aquariums. Or, Tetra can be a form of combining (as in Chemistry)

And, It's a character off of Legend of Zelda, Just saying.

no

sharks

Yes, fish do have ears inside their heads, but many do not hear sounds very well. They use what are called "latteral lines" that run along the sides of the fish. They use these to sense changes in water pressure. This is similar to the way humans ears sense atmospheric pressure changes.

The lateral line (note spelling) is not used for pressure detection, but rather for detecting water motions around found around fish (within a body length or so) up to about 100 Hz. The lateral line has nothing whatsoever in common with human pressure change detection - the receptors are different and atmospheric pressure changes are very low frequency (below 1 Hz).

The ears of many fishes are able to detect sound (particle motion) and while many species do not hear as well as humans or other mammals in air, they are sensitive enough to be able to detect the "acoustic scene," which means that fish can hear the sounds around them of biological relevance. Indeed, hearing in vertebrates evolved (in fishes) to give the animals information about their extended world, far beyond the range of vision. In effect, by using hearing, fishes (and all vertebrates) get a 3 dimensional "view" of the world around them that extends far beyond the range of other senses. This "acoustic scene"works in day and night, and enables animals to be aware of their environment.

not many. Until recently i had a 15litre 'Baby Biorb' bowl with 2 goldfish in, however it did seem quite cramped even with just those 2 in there so I have upgraded to the 30litre version.

i guess however that it depends on what type of fish you are planning on keeping, i would say that my 15litre bowl would house maybe half a dozen minnows without problems, but anything larger will just feel cramped and won't be good the for the fish's health.

hope this helps to answer your question The rule of thumb for freshwater tanks is 1 inch of fish per gallon. That'd convert to 0.7 cm per liter if you have metric fish.

Yes

yes they do

yes, neons are a tropical fish so they must have a heater. water temp should be around 68 to 79f, but somewhere in the middle is best I was thinking about 72f .

Most fish collected in the wild are netted or trapped to avoid too much damage being done to the specimens. They are then sorted and placed in holding pools or large containers to await transport to a distribution area.

Not really. There will be some bullying in the tank if the gourami is bigger than the dwarf gourami. Usually the dwarf will be left lone but there is usually fin nipping.

Almost to a fault! Oscar fish are very social and in the wild spend a lot of time playing with each other.

They are by far some of the most intelligent fish out there. In the absence of other fish they will begin to consider you their playmate.

Many oscar fish will learn to wait at a certain corner of the tank because they know you are normally home at that time. They will swim around in excitement when they see you, and follow you with their eyes as you walk around the room.

My friends oscar would often watch us watching TV, sometimes he would watch too. He seemed to really like the Harry Potter movies.
