I ordered 2 pairs to replace the a. ortega that turned out to be hybrid but received 8 fishes. My understanding is they would be a purple fish - but these aren't that purple. They are approx 1.5 to 2 inches long; show amazingly little aggression with an occasional flare. I know i have at least one male and at least 1 female but not sure of the split. My biggest concern is if they are not iprianga i need to reduce the temp (which i have at 81 right now); these photo are not great but hopefully they are good enough. The fishes are not that shy but show a lot of constant movement - the biggest surprise is what appears to be nearly 0 aggression. The tank does have a lot of layers of driftwood and rock for nooks and crannies if needed:
