Which cory type for my 75liters tall?

This 75 liters (19g) used to house a dwarf gourami who recently passed... My fish seller has restocked a variety of cories and I was hoping to get some, after replacing the bottom sand and micro pebbles with fine sand.

Here are the options:

* Green Cory.

* Julie Cory.

* Similis Cory.

* Sterbai Cory.

* Black Venezuela Corydoras.

* Gold Laser Corydoras.

Is there one you would recommend that could live well in this setup? Or would it be too small for all of them?

TIA!

My dwarf gourami suddenly passed :(

I had him in my heavily planted 19 gallon tall for about a year. In the past few months he had suddenly become very shy hiding behind plants and wood, but seemed otherwise healthy and eating well. Today I found him dead next to the sponge filter :((

My parameters currently are ammonia 0, nitrite 0 and nitrates ~30. Tankmates were 4 otos who seem to be doing well and chilling.

I couldn't spot anything wrong on his body, the coloration seemed normal and there were no lesions or bloating.

What could I have done wrong?? I feel pretty terrible for my sweet boi.

After a water change my Harlequins are schooling. I think I may have accidentally lowered the temperature by about 1C (from 28ish to now 26.5). Are they going to be ok? Anything I can do at this point?
