It looks very good to me, i dont know the specifics, but most cories prefer sand to smooth rock as they can filter it.... you probably know waaay more than me so i guess keep it going!!!

I researched extensively about the topic which is why it looks so good ,as for the corydoras catfish the reason why I started keeping them is because they were part of the tank when I started cycling it a little over a year ago and I liked them so much that I kept them and they have survived since then,I also use an undergravel filter which is the reason why I can't use sand.

This is the final result of my south american biotope blackwater aquarium as it looks like after adding a few new plants such as 10 fully grown floating plants and some other types on the bottom.

Each and every fish species in this tank exist or are even native to Brazil such as the corydoras duplicareus catfish which can only be found in a small portion of the Rio negro river in the wild.

The rummy nose tetras are my newest addition to this tank and they have been there for a couple of months by now and they are doing incredible.

What do you think of the tank so far?

It take dedication to do a tank like that, just curious what species , plants, etc there are...

This is very beautiful and even more impressive considering the thought that went into recreating a portion of a natural ecosystem. I would love to keep rummy nosed tetras someday. However, the catfish in my 75 gallon would definitely eat them and my 6 gallon couldn't possibly support a shoal (and is already occupied by the meanest betta I have ever seen).

Cories may prefer a sand substrate but in its natural habitats, they can adapt and thrive in areas which do not have a sandy bottom.
