It's weird how sometimes these work out, while other times they fail miserably. And before anyone gets mad, I know several of these fish will grow out this aquarium and they have options already lined up for when this happens.
16g bow front
7 -female bettas
1 -African Butterfly fish
1- Blue Gourami, who won't be a permanent resident.
1 -bamboo shrimp(I think, I couldn't find him this morning but he hides really good)
1 -otocinclus, when my gourami moves to another aquarium I'll buy him some buddies.
1 -1" long fin bristlenose
1 -2" bristle nose, letting him grow up some so I can put him with my cichlids
In my opinion a over stocked aquarium can only happen in a tank that is designed so they feel they are in a bigger space because there's more to explore but not over crowding the space with objects.
The large plant in the back is a tiger lotus, it grows extremely fast and eats up ammonia. The amazon swords don't get nearly enough light and stay small in size which I think is actually pretty. Java moss, and some long thin grass like plants which appear to not do well because of the light. floating anacharis, 2 anubias, marimo moss ball.
In the back right corner there is a 20g internal filter
