20 gallon stocking question

ive had this tank for a while now about 6 months its planted with soil.
filter - Marineland for up to 50 gal. with bio wheel
light - t5HO 48 watt purple/red bulbs.

currently its got a few wisteria plants and an amazon sword with some micro swords.
theres 3 pieces of driftwood on top of each other in the middle. im planning on removing the wisteria and adding four leaf clovers and baby tears with some floating plants. now heres what im planning to stock it with:

2 dwarf gourami OR 5 sparkling gourami
12 lambchop rasboras
its got 4 bronz corydoras already

is this gonna work or does this list look problematic?

only potential problem with the stocking is if you go with the dwarf gourami, be sure to research this fish as it can have health issues and can present problems in a community tank because of its temperment

Seems over stocked for a 20 gallon....

Beautiful tank though :o

How about 3 Female bettas?

They are peaceful and their wonderful colours will complement your plants.

Just gonna jump in and say that minimum number for female betta groups is 4, preferably 5 fish. And they are not peaceful with each other, many sororities fall apart. I'd head over to the betta section, we have some stickies about them if you're interested.

Dwarf gourami limits you to one fish, two will fight in that size a tank... One dwarf, the lambchops and cories should be a good choice.
I think you should be able to fit in 4-5 sparkling gourami with maybe 8-9 lambchops, plus your cories.

I agree with Quantum. I wanted dwarf gourami, too, but once I learned about the dwarf gourami iridovirus I quickly changed my mind as it is not curable and is transferable to other species. Fortunately, the honey gourami has a very similar shape (and better temperament) and is not commonly a carrier of the dg iridovirus. You could easily have a trio of one male and two females in your tank (Two dwarfs also might be a bit cramped as the males, what are commonly sold, are territorial.)

I would also add a few more cory cats, too. These guys are going to be much happier in a larger group.

Your numbers of lambchop rasbora sound great. Even if a few deaths happen, you will still have a good school. It boggles my mind when people insist on keeping schooling fish at the bare minimum recommendation.

EDIT: I did just think of one extra thing. Gourami don't like water flow. I have that filter on my 55 gal and it puts out a pretty good flow. I highly recommend baffling the water flow. I use a small aquarium sponge. The Rena brand sponge fit down in between the water outflow and the hood and really slow down the flow. It also will remove any surface current which your floating plants will like. Just cut it down to about 3 inches tall and it won't even be visible unless you remove the hood.

haha i realized i should have posted it in another section after i made the new thread i realized you cnt delete older thread so i let it be.

thanks for the feedback i really appreciate it, im gonna go with 5 sparkling gouramis and the harlequins the corys seem pretty happy, i originally had six but one of my female bolivianrams bit two of them to the point where they just looked like faces. that ram is gone now i realized bolivian rams arent really good for a 20 gallon. so i will pick up 2-3 bronze corys if i come across some, would it be okay if i got 2-3 corys of differn species?

In that small of a tank, it's probably better to just stick with one species. Bronze cories are some of the most common cories around. I'm sure you'll find some more.

I agree with others on the fish issues and your final choice. You did mention floating plants though none show in the photo...this is crucial for any gourami. The sparkling gourami will remain close to the top among plants, and they will build their bubblenest among floating plants and spawn. You will have regular spawning in that setup, and some fry will be able to survive if the floating plants are thick enough.

i mentioned that im planning on getting some, the stores nearby dont have any floating plants as far as i know. will stem plants like cabombas do good as floating plants? temporarily until i can get some amazon frogbit. i have some duckweed for now.

i asked the store owner at the shop nearby to order the sparkling gouramis for me this is the tank so far in the new house. i am aware of the sunlight, i will tape some black paper to the sides or make a DIY mini curtain for the sides, i think that would look pretty cool and unique.

oh and i also got tricked into buying some purple waffle as you can see in the picture i later realized its not aquatic but it looks awesome.
