Would this brackish water tank work?

Question

I was thinking.

2 green spotted puffers

1-2 archer fish

1 flounder/sole (dont know what type is brackish water. If you know, Tell)

2-3 black sailfin mollies

Plants:

java moss

cryptocoryne

anacharis

I dont plan on getting these fish, i just thought it would be cool to have a tank like this.

Also, if this setup would work, what size tank is acceptable.

Answer 1

i'm pretty sure those plants are freshwater, not brackish.

Answer 2

The puffers will eat the mollies and the archer could try and eat the puffers

but if you want the archers try to keep at least 4 archers as they are a shoaling fish. It is wise to buy them at the same time and keep them all the same size as large specimens can pick on smaller ones. The flounder I have no clue but these fish aren't a good match, puffers do be in a species only tank and at least 30 gallons for them.
