Need back choosing a diverse freshwater cistern?

I'm just posting up the same question as formerly but differently
i have 2 angelfish, 2 irredessant sharks, and 2 plecos
all of these fish are less than 2 inches long so can't i hang on to more fish in the tank as well?
i don't want any stern or territorial fish (like chilids)
also no guppies(i have a 10 gallon with them so dont need any)
I want colorful fish
Thank you whether you posted a anwser
What I put surrounded by my tank was a Blood Parrot (it is a ciclid) but not aggresive and a bright orange. It will feathery up your tank.
get some neon tetras there cool or get xray tetras you can see right through them its awsome
Answers:    Why not neon tetras and zebra dianos? both are colorful fast moving school fish And I have some black mollies that are my moment choice.
Fish compatibility question?   What do I nurture my Plecostomus fish?   AFRICAN   Malawi  CICHLID?   I bought a chinese algae  eater yestrerday?
