Betta Fish Tanks
Betta fish are relatively easy to care for and their low maintenance is
particularly appealing to people who would like to have fish but don’t
have a lot of time to care for them.
If you are keeping your Betta fish in a jar or bowl (not recommended)
you should keep your Betta in a big enough container so that he can
swim around and not bump or tear his fins or scales. Also be sure there
is plenty of surface area so that he can get enough oxygen.
Even though Bettas
do well in waters that have low
oxygen levels, it does not mean they require less
oxygen than other fish. Bettas have a special labyrinth
organ that allows them to breath air directly from the
surface. In fact they have to do so. Experiments have
shown that when the labyrinth organ is removed, the
fish dies from suffocation even though the water is
saturated with oxygen. Ultimately Bettas have to
breath air from the atmosphere and need access to
the water surface to do so.
Your Betta fish does not require a filtration system but you must
provide it with the cleanest water possible. You should change out a
third of the water every three days so it stays fresh and clean and
keeps your Betta from getting bacterial or fungal infections. Aged
water should be used to replace the old water. You can age your water
by setting it out for at least 24 hours. You might also want to invest
in a product like Bio-Safe Water Conditioner that removes chlorine and
other chemicals from tap water.
If you are using an aquarium chances are you have more than just a
Betta fish in it. (note - Betta’s can be coupled with algae eaters,
guppies, or corydorus catfish safely). In this case you will likely
have a filtration system. Optimally the water for keeping healthy
Bettas should be soft, warm, with a neutral to slightly acidic pH.
Water movement should be kept to a minimum and this means that power
filters and powerheads are not suitable.
The PH of your tank should be about 7.0. You can get a PH testing kit
at your pet store along with solutions to minimize or increase the PH
of your water.
All tanks need biological and mechanical filtration to maintain a
Three Types of Filtration
In aquariums there can be three types of filtration processes - biological, chemical, and mechanical.
All tanks need at least some form of biological and mechanical
filtration to maintain a healthy environment. It's a good idea to
understand the basics of each type of filtration so you can make an
informed decision when selecting a filter.
Mechanical filtration involves the removal of particles of waste by
passing water continuously through foam or other porous material. The
filter traps particles of debris, and is periodically cleaned or
replaced. Because solid waste is constantly being produced in your
tank, a mechanical filter of some type is a must.
Chemical - In
chemical filtration water is passed though material such as carbon,
which removes at least some of the dissolved materials. Toxic metals,
ammonia, and even odors can be filtered out chemically. While chemical
filtration is not absolutely required, it can be useful combined with
other filtration methods. Chemical filtration is particularly helpful
when starting a new tank, because it can remove ammonia
Biological - Fish produce wastes which cannot be filtered completely
using mechanical or chemical methods. Unless these wastes are removed,
over time they will build up to a lethal level.
In Biological filtration,
of beneficial bacteria known as "nitrofiers" grow in the tank
and convert harmful wastes into something less harmful. All aquariums
need to have successful biological filtration in order for the fish to
remain healthy.Typically it takes about a month to establish a
flourishing biological colony that will effectively filter all the
Basic filter types include:
Box filters, Cannister filters
Fluidized bed filters
Power filters - do not use with Bettas
Underground filters (UGF)
Check with your local pet shop for more information on what type to use
with your particular set up.
I like using Fluval ceramic rings to promote water purifying bacteria.
