Is this container set up okay?

-4 female bettas
-2 platties
-1 goldfish
-2 julii cories
hmmm. i would own to say no just beacuse the goldfish are cold water fish, even though they can live within tropical temperatures...
they also need at least 30-55 gallons as okay since they are so messy.

otherwise good set up!
Like human beings, do fish drink wet...
yes, but if you are just setting up the tank don't put that masses fish in all at once , start w/ 4 fish for about 4 weeks consequently add 2 at a time
w/ the weeks to follow ( two per week ) you have to get an atmosphere started within the tank 1st before you put in a bunch of fish
nope sorry
2 glofish (not goldfish) chasing the 3rd?
take away the gold ingots fish they get to big
What size of cistern should I own...
Answers:    What's the tank size you're keeping them in? If you're merely asking if they get along then it's ok although depending on the goldfish he can carry pretty big and will be more like a pond koi, at least 20 gallons to start with but you will probably enjoy to upgrade as they grow larger.
Where do you find those containers that betta breeders put their males within?   Can a oscar fish live within a 20 gallon cistern?   How do you know whether your beta fish are hungry?   Can you put rattan sticks/rods bought from widespread stores surrounded by an aquarium?
