Generally it's not. I guess the off chance of having a guppy survive their full life span in a bowl is uncommon. They need heat, around 25 degrees Celsius to stay happy, because in the wild they live in warm water. But the majority of aquariums are kept at 25-26 degrees Celsius or about 75-82 degree…

The bare minimum is once a week, so it really depends on how much you feed them each serving. Just remember to keep their water clean by changing about 25% of the water once a week. Try it and you will have healthy vibrant guppies swimming all over your tank! By using a fish food such as TetraCo…

No! One neon tetra alone needs at least a one gallon tank, and neon tetras should be kept in schools of five or more! Therefore, you need at least 5 gallons for neon tetras. That is pretty small, because tetras need filtered and heated water. They will not survive otherwise. A 5 or 10 gallon tan…

If you have a male and a female they will breed when they are old enough. Since they have live babies you must have some type of very thick grass for the babies to hide in so they won't be eatten. You also could use the net containers that hang inside the aquarium. If you do that, put the female in …

The short answer is yes, the problem will not be with them killing each other, but there are several other things to consider. First, a breeding pair will probably kill or at least traumatize other inhabitants of the aquarium, so they need to be by themselves. Second, it is impossible to tell if you…

Just about all fish on this planet breed in late spring or early summer. Tetras are no different. Tetras come from South America, so over there, young as well as all young fry have a better chance of making it through the winter months. It's just natures way of being.

Yes, they need a tropical tank with filter, heater and light. 70-79 degrees is optimal for most tropical fish. I kept several neon tetras for years, they are mellow and easy to care for but tend to die if you do not take good care of the PH and parasites. Other breeds are hardier, but they can do fi…

Answer You could, but there is no gaurantee that they will survive long. Tetras like their water to be around 70-72 degrees and all fish love a filter. It keeps you from having to clean the take so often and the fish live longer. They do make heaters and filters specifically for fish bowls betwe…

This is probably part of a mating ritual. The female will "test" the male's strength when she decides if she should spawn (lay eggs) with him. Do you have any slate rocks in your tank?
