First welcome. Second have you researched caring for goldies? One Goldie requires a 20g & then each additional Goldie requires another 10g so for just two you need a minimum of a 30g tank. They have a huge bio load so they may require more water changes than other fish especiallymif you have multiples. Also they need a varied & good diet that includes veggies. As for your 10g if you want to do a fish LESS cycle it typically takes a little less time, my suggestion is to, if possible, have both filters running on your larger tank for a few weeks & then move the one to the 10g & your tank will pretty much be cycled, if your larger tank is cycled. You should read the stickies regarding cycling & then ask questions. A Betta will absolutely LOVE a 10g tank. Oh, if it doesn't have an adjustable heater which I doubt since you had Goldie's in it, you need to get one because Bettas are tropical & need water 78-80. They love lots of plants (java fern, annubias, hornwort, water wisteria, water sprite, swords) with some that are floaters or tall enough they can rest on them close to the surface. They also like caves. You can use sand, I like the pea gravel so its all personal preference. In 3 of my tanks I have real & silk plants, the silk were because my real plants weren't tall enough yet. Even though your filter has a low setting you may still need to baffle in some manner but you'll have to see once you get your Betta. As for food I have a variety, New Life Spectrum pellets, Omega One flakes, Top Fin Betta Bits, frozen blood worms, brine shrimp & daphnia, as well as on very rare occasions freeze dried blood worms.
