Well if you’re going to get a jack demspy, at least get an electric blue jack dempsy. Those things are wow
Personally though I’d do something like this-
4 Bolivian Rams
12 pseudomugil gertrudae
10 Threadfin Rainbows
8 Neon Dwarf Rainbows
3 Goby Plecos
Toss in 20 odd rcs or ghost shrimp or amanos for clean up.
The setup could be an eheim cantister filter (like a 2217, that will keep it CLEAN), fine sand substrate with lots of manzanita for hiding (Rams really love caves, they breed in them), maybe some rock piles scaped in. Wrap java moss, christmas moss and java ferns on the manzi. Then add easy plants. Crypts towards the front with dwarf sag, then swords and easy stems in the back. Add floating plants like frogbit to the top for cover.
The Rams could either be two male/female pairs or a male with three ladies. Two males will spar a little and establish territory, but a single male with all those ladies will just be happy. Rainbows are incredibly entertaining schooling fish, which is why I listed the Pseudomugils, threadfins and Neon Dwarfs. Also all three are very different in terms of shape and size, do you’d get a lot of variety. The three goby plecos (more commonly known as pitbull plecos) are killer glass cleaners. They are roughly the size of ottos but are a lot tougher. Finally the small amount of shrimp it to just give the tank something to clean up the scraps as well as a little live food for the fishies. The shrimp will pick up bits of food and if they have any babies they may be snacked on by your community (which, deepens the color of your fish
Anywho, that’s just my suggestion. You’re near the bay area which is where I live, and all of the fish I listed are readily available down here. Rainbows are on the pricier side, but if I was going to do a 40 gal, I’d make it one of those whoa tanks, ya know? You could also try aquabid.
