Hello, I have been interested in getting into this hobby for awhile, so after research, I was thinking about doing this for a 20 gallon tank.

5 Corydoras
5 Tetras
5 danios
1 gourami

Would this be considered overstocked? I think it might be, but I want to see if more experienced people think so. If it is I would greatly appreciate feedback and suggestions.

No. You should be aiming for 6 schooling fish per group. And tetras... well I keep neons, rhummy nose and congos... all vastly different. What types? Same for danios. What type?

Hope that helps!

I was considering neon tetras and rose danios. Would 6 of each schooling fish be overstocked? If so, what do you suggest I change?

I'm not sure I'd do that many schools in a 20. I'd do the cories, then pick which you like more: The tetras or the danios. And what kind of gourami?

Is this a 20 gallon high or long?

Either way it would be better to stick with one middle schooling fish

What type of gourami?

I personal believe that upping your stock to 6 from 5 wont do much difference but more.is.always better for.schooling fish

Thank you everyone for the feedback! I am planning to use a 20 gallon high and using a dwarf gourami. I think I'll go tetras over danios. So right now I'm planning on going with this:
6 panda corydoras
6 neon tetras
1 dwarf gourami

If there's a good top dwelling fish, or top dwelling gourami that I could replace the dwarf gourami with? From what I've heard they're bottom dwellers.

Maybe mine were strange, but my honey gouramis stayed towards the top. They're smaller and more peacefuul than DGs, but very social. I kept 2 males in my 20 long without many issues, just occasional chasing.

I would up the cories and neons to 8, you have room for more and they are happier in larger groups

Thanks so much for the input! I'll do some research on those. In the meantime, if anybody has some more suggestions for top dwellers, let me know.

About uping the Cory and tetra count, I'm not sure I'd have enough room. Once I have everything set up and there's room, I'll be sure to add more.

I'd up the neons but not the cories. Just my opinion though.

Someone correct me if I'm wrong but don't panda cories need cooler temps then the DG? Other then that ur stocking sounds great. I would start with the neons and then the corys and add the DG last.

Also I was wondering, could I replace the gourami with 6 rose danios? I really prefer small schooling fish, so if there's other suggestions, feel free to give them.

No, I would just do one mid dwelling school in a 20 gallon (unless they are tiny nano fish like CPD or ember tetras)
1 DG takes up a lot less tank space than 6 rose danios

So now it looks like I'm doing:
6 neon tetras
6 panda corys
1 honey gourami

I would still prefer a few small fish over the HG, but this seems great. Thanks everyone for the feedback!

I think you could pull off two HG, but I'm a notorious 'overstocker'.

Neons are fragile, I wouldn't even buy them. Cardinals instead?

You could replace the honey gourami with 2-3 nicely colored male guppies.

I think 8 neons, 5 corys, and 3 guppies is very doable. If you are just starting, I would suggest starting with just the 5 corys and 3 guppies. Once established, and tank is good to go, you can add in the more sensitive neons, maybe 4 one week, and 4 more a few weeks after that. This gives your beneficial bacteria/biofilter time to catch up.

I feel like neons would nip at the guppies fins. And you'd need more than 2-3 males for a successful fraternity (personal experience).
