Hello, and Welcome to the wonderful world of being a betta Mommy..and yes, this site is great!! You will learn a lot about betta's and what to do to give them the best life possible:)
When we first got our betta, Sammy.. I upgraded the standard size bowl, to a critter keeper, to a 3 gal tank, because I was unaware of what a betta's needs are.. (Sammy is my daughter's fish) but I already take care of him all the time..
I give him Haikari Gold micro pellets, according to feeding dir. and he has a Tetra 2/10 heater and the temp is a consistant 78d.
And don't forget to add a thermometer to watch the temp to see if it's a 78-80deg. (which it should be)
And I have a combo of Silk and one Live plant..and a place to hide away..to rest and sleep.. and of course some gravel, and overlying stones, for decor..
And yes, you will want to invest in a good Gravel Siphon for Vaccuming..Hope this helps..
Glad to have you here..Can't wait to see pix of your baby soon:)
