I have seen them now. They’re not tweediei but have a lot of blue in their fins. White to light blue ventral filaments, so most likely alfredi or some closely related form. I saw some of them displaying, so they seem to do fine in the store. Caudal fin band mostly brightly red, like in tweediei, with no significant blue part.
I’ll get some of them soon.
Does anyone know of a Dutch keeper of real tweediei? Seems like I am the only one in the country keeping this species… That’s way too few keepers for a safe population! I saw some fry last few days though, so there is hope…
