2.5 is the minimum but 5 or more is recommended
in other words 2.5 is ok but i wouldn’t recommend it but 5+ is great so if you can do more than 5 gallons that will always be appreciated by your betta
a little on the smaller side but an okay tankfor a betta, the filter might have too heavy of a flow for longer finned bettas and if you can get one bigger than this one pls do
perfect sized aquarium with a nice built in filter
another great sized aquarium with a built in filter
starter kit that has tanks from 5-55 gallons, comes with filter
please note that even if the tank comes with a filter you may have to replace it because the flow might be too strong
(all these tanks are from the petsmart website)
bettas NEED heater to thrive
they will be miserable or even possibly die with out one as they are tropical fish
-buy filters according to tank size
-bettas need 78-80 degree water so get one that is preset to that temp or get one that you can set the temp yourself
i have this one, it’s 25 watts and perfect for a 5 gallon tank
most heaters you will find in pet stores will be preset so you need to look for the temperature and watts
-the general rule for watts is 3-5 watts per gallon (so for 5 gallons you want about 25 watts)
-look for a preset temp of about 78 degrees
bettas are bad swimmers. thats just the facts. filters that are gentle enough for bettas are really hard to find but here’s the one i use
it has an adjustable flow so it accommodates betta fish very well
some tanks also have gentle flow filters or filters meant for bettas built in which are also good to look for
-remember that you have to change out the filter cartridges about every month
when you clean your tank you need a syphon
which is one of these bois
get one with a pump cause if you get one without it you will have to start it with tour mouth and we don’t wanna risk gettin diseases
you need to do a 10-20% water change every week and if that’s too much work than well my friend fish keeping is not for you because this is an absolute necessity to a happy and healthy fish
(for a 5 gallon tank changing out 1-2 gallons a week is recommended)
i made this for a friend who had some questions about betta care, i only brushed the surface in this post but feel free to ask me if you have more questions and please for the love of god do your own research because you should never rely on a single source
if i got anything wrong or used any bad products as examples in this post please correct me so i can change it
