How do we take care of our Betta Fish?

If your betta is in a tank or bowl that is 2.5 gallons or smaller, you should change 100% of the water once a week. If it's a 5 to 10 gallon, then change 50% to 75% of the water each week. Make sure that the new water you add back in is the same temperature of the old water, and use a water conditioner.Your betta only needs to be fed 2 to 3 betta pellets at a time two times per day.

Can any kind of fish survive in a fish bowl with no filters?

Betta fish are about the only kind of fish that can survive with no filter. They prefer still water or a very gentle current, so as long as you are keeping their water warm and clean (at least 80* F) they will thrive in a one gallon, unfiltered bowl. Change the water at least weekly to keep a one-gallon betta tank clean. Change more often in anything smaller (and it's not recommended to keep them in anything smaller).


Could 2 Cherry Barbs fit in a 1 gallon tank?

Not a chance. They are active fish that like living in schools and would be miserable in such a tiny tank. The only fish that could comfortably live in a tank this size is a betta. Even a betta should ideally have a bigger tank, but will be comfortable in one gallon if 70% water changes are done weekly, RELIGIOUSLY. NEVER skip a water change.


1 gallon tank what type of fish can you put in it?

A 1 gallon tank could have one betta fish, but you will need to be diligent about changing the water on a regular basis. The smallest tank that should be used, even for a betta, is a 2.5 gallon tank as it at least gives the fish swimming room.

Can you have 6 neon tetras 2 ghost shrimp and a betta fish in a 10 gallon aquarium?

It might be a little crowded, but you should be okay with regular water changes. Be careful though because guppies breed readily and with 5 of them you will have a lot of baby guppies and that will definitely overcrowd your tank.
