Yes, a betta can live and thrive in a fishbowl, but only if
you do frequent water changes.
However, note that a bowl is certainly on the smaller side
for any tropical fish, including betta, so consider a filtered and heated
2.5-gallon aquarium for better fish safety and health.
Most starter kits (2.5-gallon)even come with a light already
installed.
Keeping
betta fish in a bowl does not mean adding water; your fish will die within days
if you do that. The setup needs to be a replica of an underwater ecosystem,
meaning you have to delicately balance several elements to be successful.
That said, a filter is quite crucial in a fish tank, but
betta fish are hardy and will survive in the bowl even without one, albeit more
susceptible to infections such as fin rot.
Betta fish are a tropical species, so they need a heater in
their tank as well, though it' might not be feasible when keeping one in a
bowl. In which case, find a way to keep your water warm, making sure it does
not get too cold, especially during the colder months.
For more insight on keeping betta fish in a bowl, please
read on.
Can Betta Fish Live Without a Filter
in The Bowl?
Most bowls cannot accommodate an average-sized aquarium
filter, but people still keep betta fish in fishbowls successfully.
So Yes, a betta fish can live in a bowl with no filter.
Besides, the strong current from an aquarium filter in a
small bowl will do more harm than good. The current, will very likely, tose
your fish around and stress it, especially since bettas are not the best
swimmer out there.
However, for your fish to survive in such an environment,
the right care is paramount. So much so because many new fish owners assume
that bowls mean less work and are less expensive, which then leads to neglected
betta fish battling numerous infections and with a less than optimal lifespan.
In context, the only reason betta fish can live in a bowl
without a filter is because they have a labyrinth organ that helps them breathe
air from the water surface. But these only aids the fish to breathe, but to
keep your aquarium safe for the fish, use these tips:
- Do frequent, large water
changes, at least two times every week replacing a third (30 percent) of
the bowl with lukewarm water. This will keep toxic wastes and chemicals
like ammonia out of the fishbowl, which would otherwise poison your betta.
- Try not to overfeed your betta,
especially because a bowl is quite small and any leftover food will
decompose and release ammonia in the water, akin to that produced by fish
waste. And with no filter to expel the ammonia, your fish will end up
getting ammonia poisoning.
- Clean your fishbowl frequently,
maybe even with every water change, making sure you remove all debris on
the glass, substrate, plants, and decor.
- Apart from adding a lush green
in your bowl, live plants can also help clean your water column, so
consider adding a plant or two in the betta bowl. Even so, make sure the
plant does not take away much of the already limited water space from your
betta.
Can Betta Fish Live Without a Heater
in A Bowl?
As I mentioned before, bettas are a tropical fish species
that require a water temperature anywhere from 72° F to 77° F,
and to provide them with this stable environment, you need a heater.
If by any chance you cannot get a heater for your fishbowl,
try keeping the bowl in a warm part of the room where the temperature does not
drop too low.
Plus, with every water change, refill the bowl with lukewarm
water to keep the temperature stable.
Overall, appreciate there are smaller heaters available for
bowls and aquariums in rooms that fluctuate in temperature which I recommend
getting instead of maintaining your betta without a heater.
How Long Can A Betta Live in A
Fishbowl?
Bettas that are kept in an ideal 2.5-gallon fish tank with a
filter and heater are quite capable of living for up to five (5) years. But in
a fishbowl, they live for less than half their average
lifespan, sometimes even for less than a year.
I have one that lived for nearly two (2) years in a bowl
with regular cleaning of the tank and water changes twice a week and anytime
the water is visibly dirty (cloudy).
So, if you must keep your in a bowl, make sure you maintain
the fishbowl to the best of your ability, and consider moving your betta to a
larger tank as soon as it attains adult size.
What Should You Put in Your Betta
Fish Bowl?
Apart from a filter and heater, betta fish also appreciate
some plant cover in the tank especially floating species where they can hide
in.
Floating plants are best for betta
tanks because these fish like to hang around the water
surface at the top.
As for tank mates, betta prefer to live alone in solitary,
especially the male fish.But this does not mean bettas don’t get lonely,
so to keep them busy, add a few toys in the tank or fishbowl for your betta to
explore.
You may also want to leave a few toys outside the tank or on
the glass, for your betta to investigate.
Nonetheless, bottom-dweller like cory catfish can be kept with betta fish
in a large aquariums (at least 20 gallons). But avoid fish like fancy guppies
that have bright colors and flowy fins as they can be considered a threat by
the betta.
What Other Fish Can Live in A Fish
Bowl (Nano Tanks) Without A Filter?
Apart from betta fish, there are a few more tropical fish
species that can survive in a fishbowl without a filter, although this living
situation is not always recommended.
A majority of them are quite hardy and are in fact used
quite often to cycle new fish tanks.
- Guppies: Have tiny bodies and are arguably one of the hardiest
species of tropical fish there is.
- Zebra danios
- White Cloud Mountain Minnow
- Pea puffer fish
- Ember tetras
Please note most of these fish will do better in a nano tank (2.5
to 5-gallon tank) not conventional fishbowl. Plus DO NOT keep
a goldfish in a bowl, it won’t fit!
