Like BlkG35 said..... you should decide on which variant and then you'll get a better idea of the costs. Bluechipaquatics has a pretty nice collection to choose from also..... but if you're looking to buy from a fellow hobbyist, try Cyphos.com and/or Cichlidforum.com in the buy/sell section. If you were closer I'd sell you the last of my collection, just Burundi's though.
i looked through the different kinds and i really dont care about the subtle differences, i just want them at the right size, the cheapest kind are fine with me lol, which are the least expensive and how much should i be lookin to pay for 6"-8" 1M/3F?
