Pygmy corydora questions

[Aquarium.girl]

Hello,

I have a 10-gallon with 2 neon tetras, 4 dalmatian mollies, and 1 ghost shrimp (I'm going to get 2 more). How many pygmy corydoras should I get?

You need to get more neon tetras because they are school fish, at least 10 specimens, although it is likely that with the size of your tank you will have to remove those mollies or you will have overpopulation. 5-6 pygmy corydoras should be fine.

i would get rid of the mollies and get 5-6 more neon tetras they need to school and get 3 pygmy cories for that size of tank.

Do Pygmys work on cleaning up the substrate? I’ve heard they spend more time in the water column unlinked other corys.
