well i would suggest getting the end of a pen and putting it in the water and if they touch it, give them a treat. do this daily. when they follow the pen, put the hoop in the water and the pen on the other side. hopefully they will swim through it. each day move the hoop a little higher until it is abbove the water, and again hopefully, it will jump through the hoop

yes it is

You should change at least 50% of the water in your tank each week at minimum. If your tank is too small, to over-stocked, or you do not have enough filtration, then you will need to change the water more frequently.

A small breed of fish is guppies or tetras. In our science lab there is a fishtank with guppies and tetras in it and they are pretts small. Feeder goldfish are also small, i have two and they are about an inch each.

A fish has to be alive in order to prevent it from sinking, When it dies the water pushes it down just like everything else that is at the bottom of your aquarium. They have no air in them so they won't float.

Yes, if plants were grown in a totally artificial medium, without any source of nutrients and then watered with distilled water they would wilt and evenetually die.

This is because distilled water has no nutrients, and therefore Osmosis cannot occur. besides this, they would yellow and die as there is no nutrients in the water to support continued growth

2 Tetras = 2 gallons, 2 mollys = 6 gallons, 2 guppies = 2 gallons, 1 Betta = 3 gallons. Provided your tank holds a bit more than 15 gallons of water (about 20 gals) and your filter will handle the job, there is no reason I can think of that would stop you putting a Siamese Fighter (Betta splendens) in the tank with the fish species you mention.

Your betta is probably doing this because your water quality is not within healthy limits. If you haven't been doing consistent weekly water changes then the water could contain extremely high amounts of ammonia and nitrite or even nitrate. Water changes are needed regularly and if not done ammonia molecules which are bonded to oxygen molecules by nitrosomas bacteria will buildup and make it extremely hard for the fish to breath. Thus explaining the lethargic behavior. This can result in irreversible gill damage. Do a water quality test to check if your waters within safe perimeters. If not do several large 50-75% water changes until the ammonia, nitrite and/or nitrate levels drop.

Another reason why the fish could be acting this way is if it is sick. Usually an internal bacterial infection causes a fish to lose the ability to maintain proper buoyancy because the swim bladder may fill with fluid. Other than bacteria being the problem your fish may be sitting at the bottom because its being bombarded by parasites (such as flukes).

Treatment:

Try doing several large water changes, treat the tank for parasites using an anti-parasitic medication and feed the fish an antibacterial medicated food.

If a betta's eyes are growing unevenly, it can be caused by a tumor. it can also be caused by a genetic condition.

it probley means that your betta is sick. Look up on websites to see if you can diagnose your betta with any sickness. I realize my data was sick after he died so look sicknesses up fast. Hope this helps.

Piranhas are tropical fish, so yes. However, there are other fish you can keep them with as well. Just what depends on the species of piranha.

Note that most species of piranha that are suitable for aquariums will see all other fish as food, so if you put other fish in the aquarium with them they will proceed to dine on the food you so kindly provided.

no. i do not recommend putting betta fish in sunlight. it even says it on petco containers and other websites also say its not a good idea... duller light is better.

Many many many fish get along with guppies. Guppies are very peaceful live bearing fish. They breed readily in the aquarium and quite prolifically if left unchecked.

Some suggested tank mates are, most kinds of tetras (not all), rasboras, danios, platys, mollies, swordtails, cherry barbs, gold barbs, just to name a few. Look up info online about guppies and most info will list suitable tanks mates.

I believe you mean Betta fish. No, it should be fine. You can treat you Betta fish by giving them bloodworms!

Well, there are many places that warm water fish can be found. Not suprisingly, they live in hot places such as the Bahamas and the Caribbean to name just two. The name of the fish is really the answer to where they live. Hot Country = warm water = warm water fish. Hope that helped

Fish have around 30,40,or 50 teeth depending on size.

He's probably sick. Bettas get very stressed by being kept in a bowl. Bettas, like most other fish, like to swim around. A single betta needs a 6-10 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.

In order for you to have your Bettas breed there are several things you must do. The smallest tank in which to breed them is a well established, well planted 18"x10"x10". It must have a cycled filter runing permanently, be heated to around 78F and have a pH of around pH6.8. Either the male or female can be housed in this tank. Once both male and female are in good breeding condition, the pair can be introduced by adding the stranger to the breeding tank. The male, upon seeing the female, should almost immediately show off and chase her. He will then built a nest of bubbles. Once they have finished spawning, the female must be removed or he will kill her. He should be left to care for the young until they are free swimming and then he must be separated from them otherwise he will eat them.

You are obviously not keeping the fish in proper conditions. If you follow the rules below you will have less problems. First do a water change ASAP.

The rules are :- 1 inch of fish needs at least 1 gallon of water. (A Betta is at least a 3" fish) :- Every tank needs a fully cycled filter running permanently. :- Every tank needs at least 50% of its water replaced every week. Bettas need to be kept at 78F in neutral to slightly acid water pH 6.8 to 7. Bettas should be fed as much dried food as they will eat in 15 minutes each morning and evening. (Never leave uneaten dried food in the tank. It will poison the water.) If you follow the above basics your Betta will live a reasonably happy life. If you miss out on any of the above I can guarantee that the fish will be constantly getting sick and will live a shortened life span.

yes, goldfish and betta fish fight.One time I had 2 goldfish and one bit the other one and it killed it.Never have 2 betta fish in the same aquarium or bowl because they will fight right when they get in the aquarium/bowl!

No fish likes to be in bad water although there are some species that have developed methods of surviving in these bad low Oxygen conditions. The Anabantid family which includes the Betta and the Gouramies have developed a "Labyrinth" which allows them to get oxygen from the air by means of a chamber in their skull are some that can survive in poor water conditions. You should still follow the basic rules of fish keeping if you want to be successfull keeping fish. The rules are. :-1 inch of fish needs at least 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank needs at least 50% of its water changed every week. If you keep to the above rules, and feed the fish good food it/they will stand a chance of living a normal lifespan. If you fail in any of them I can guarantee that your fish will be constantly getting sick and will have a very short lifespan.

Deadly fish are fish that can cause death. Examples are the lionfish, scorpionfish, and many of the larger and more aggressive sharks.

Bettas are by nature round in the body. It eh fish is kept in a small container it will however probably suffer through lack of swim space. The basic rules for successfull fish keeping are. :- 1 inch of fish needs a minimum of 1 gallon of water. (A Betta is at least a 3" fish so it needs a minimum of 3 gallons of water. 10 gallons is better.) :- Every tank needs a permananently running cycled filter. :- Every tank needs at least 50% of its water replaced every week. Keepyour water at the right temperature and follow the above rules and your fish stand a reasonable chance of survival. Fail in any of them and I can guarantee that your fish will have constant health problems.

the longest fish i would have to say is a koi fish. a Japanese fish that are related to the common carp but are very pretty and extremely social. my uncle raises them and has had one for about twenty years now and he is still strutting along. It is also necessary to add that Koi are pond fish since they will grow to more than 24inches long. For a pet fish in a largeish aquarium, (no smaller than a 36 inch tank for 1 fish) provided you look after it correctly, an Oscar (Astronotus ocellatus) lives for many years, becomes very friendly, recognises people and things outside the tank and shows heaps of personality
