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 between 2 and 5 gallons. White cloud mountain minnows are probably the best fish that you could keep in a bowl without a filter or heater.
Yes, since Guppies and Neon Tetras are small fish (and stay small), there should be no problem with them living comfortably in a 2 gallon tank. You should add a little filter and air bubble combo to keep the water clean and aerated. Since these are tropical fish, you should also add a small heater and a thermometer. Goldfish do not need a heater but tropical fish do.
The fish bowl must be at least 1 gallon. You can fit 3-5 tetras in there. However, if you put them in a fish tank with a filter, they will live longer and will be healthier.
You should only have 1 fish per gallon of water in a fish tank. I wouldn't put more than 2 or 3 Neon Tetras in a 4 gallon aquarium with 1 Betta.
Yes provided the tank is large enough and properly maintained with a good filter and weekly water changes of 50%. To avoid problems from overstocking, you will need at least 1 gallon of water for each 1 inch of fish length.
No fish can live successfully in a bowl. Far better you either throw the bowl away or use it as a vase. If you really want to keep fish get a reasonable sized aquarium to keep your fish in. There is a basic rule that all successfull fish keepers use and that rule is "1 inch of fish needs a minimum of 1 gallon of water" For you to keep 2 Tetras successfully you would need at least a nominal 5 gallon tank with a heater/thermostat (set at 75F), thermometer, Cycled filter, coverglass, Lights, gravel, and live plants.
That is fine. You might consider getting some corydoras catfish.
Yes. If you keep up with small weekly water changes (about 25% of the tank's volume), then you should be quite alright. Having a planted tank helps filter out some of the toxins produced by fish waste so that helps. I'm also assuming you have the minimum acceptable filter capacity.
You would probably be fine with 5-10 neon tetras.
they are fast fish feed them flakes or blood worms watch out for the filter they get sucked in easily Oh ok and are there any special cleaning techeneces i should use?
Provided you don't overstock there is no reason why not. 1 inch of fish needs at least 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank must have at least 50% of its water replaced every week.
In a 40-gallon aquarium, there are 21 neon tetras and 7 zebra danio fish. Write the ratio of neon tetras to zebra danio fish in simplest form.
The rule of thumb is to keep no more than 1" of fish per gallon.
