Funny I had breeder managuense back in the 80s that would produce about half dozen gold morphs (no black markings) per spawn, and used the golds as feeders.
Here's xCichlasoma ornatum, it's been available from a number of vendors lately
Got mine from Wet Spot last spring

Not quite sure why bar less festae are important, my female seems to go back n forth at will.

And here where I live, at times, at local aquarium auctions, dovii go for a buck a bag.
I bought a bag of 6 fry for $1 because there had been so bags, they had a hard time giving them away.
LFSs usually sell them for about $10-$15

My holy grail would be Nandopsis ramsdeni, Heterochromis multidens, and/or Iranocichla hormuzensus. Last I saw any of each on vendor lists, they were around $300 each, but because I prefer to buy groups of 6 or more, the price took me out of contention.
