Helene, those are fantastic looking fishes and your photos really capture the beauty of them :cheer: . These really are tricky to ID not knowing the collection location – the several forms just look very similar. I think Peter’s explanation of this whole situation in a previous thread around these fishes, is well taken by me.
Today my P. spec.”TCE 2015″ spawned (see my photos there). My fish look similar, except that when spawning today, the male showed almost no red.
I have recieved P. tweediei from a verified collection location, Sri Bunian, in Johor, Malaysia. These are F1 fishes of the ones Lawrence Kent and Peter Beyer collected in Dec. 2014. (Photos of those wild fish is in the species account on the website.) Once they grow out I will photograph them and post to the forum for comparison.
In any case, good luck with raising the young. (What water parameters do you have, maybe something with temperature or pH affects ratio of males to females. As with other fishes this could be something with which to experiment).
