Now the reference-species: Three times Parosphromenus alfredi “Sedili” self caught 2009.
First pic shows a male after capture in Sedili (pic N. Neugebauer), they are very red because of shrimp
Second a male of F2 or F3-generation (shows the lack of red markings in caudal, dorsal and anal fin)
Third shows a young male of F5-generation (alter getting grindal, fed with beta-carotinoids)
Fourth is the famous P. cf. alfredi “Mimbon1998” with only a little red colours because we didn`t know to feed carotinoids They had very nice long whitish ventral filaments. In my opinion also a. P. alfredi from another origin.
We can see a lot of difference (also) in cause of food.
