80 Gallon (48"x18"x22")

Greetings;
I'm wanting to rebuild my 80 gallon tank. Currently it has 1 Red Oscar and 2 common Plecos. They are going to a new home.
I'm thinking of going Amazon area dwarf cichlids, Apistogramma genus and some Characidae or Characin and or Rasboras to round things out.
I plan to stack flagstone making lots of caves and areas to grow live plants. Lots of live plants on a pool filter sand base.
I have well water and it is very soft 2 KH & 3 GH. Ph 6.7, out of the tap. I plan to put peat moss in the basket of my Mag 350 lowering the PH to about 6 - 6.5.

This is what my research has given me for ideas so far

Fish I am considering are

Apistogramma Cacatuoides
Apistogramma Steinadchneri
Apistogramma Macmasteri

Plants

Echinodorus amazonicus (Amazon Sword) (as a centerpiece background)
Heteranthera zosterifolia (Star grass)
Anubias Nana (Dwarf Anubias) (here and there plant)
Zephyranthes candida (Crinum "Dwarf" onion plant) (center)

So have I hit my mark or am I way off.
Wasn't sure where to put this and rather than posting it twice in Planted Aquariums and Cichlids so I thought I'd hope for the best and post it here.
Thanks in advance,
Jim

Well I got my sand today, #100 All-purpose sand.

I'm down to considering 2 or 3 schools of the following

Apistogramma cacatuoides sunburst

Agassizii Triple Red
Apistogramma Borelli Opal pistogramma
Apistogramma Macmasteri

Schools of

Corydoras Adolfoi

Corydoras Panda

I haven't come close to making up my mind about the Rasboras.
