  i am getting a started betta kid and i am getting my betta the same time i get my tank how much time dose it take to make the tank cause i dont my betta to be the plastic bag for too long thank you
A betta starter kit can range from 1 gallon through to 5 gallons i just want to advice you that a minimum for a betta is 3 gallons 5 is better and you should cycle the tank first before adding the betta just make sure the kit comes with a filter and heater
depending on how fast you are the betta could be put in a bowl or cup of water just make sure the waterr is dechlorinatted and he wont die then once youre done making the tank put him in
depends on how well you can follow instructions
