Whew! Your thread is making me dizzy, my head is spinning (Tommy James & The Shondells reference, lol...yep, I'm old ). So you have 2 angels in a tank barely big enough for them (but 1 is stunted) & want to add how many dwarf cichlids of how many species? And tetras ? & maybe something else? NO!!, You have or want more than 3 smallish tanks can handle healthfully.
Can you please update the fish & tanks you realistically have or will have very shortly. Breeding fish needs room, water changes, appropriate foods & usually space away from the adults. Oh & a plan for any fry that will (hopefully) grow to a sellable size? I've been there, even "cool" fish need a market...especially 1s like cichlids that may breed every 30 days...
I'm not trying to crush your dreams, just suggesting you slow down. Get a bit of experience with 1 species & at least another tank or 2. I understand the economics of buying a bunch of fish at 1 time...but it doesn't hold up over time, a short time....& then there's the work of many tanks.. Go slow is my best advice, think some more!
