Before I will show some more pictures of species references with shure origins, I will try to clear something:
The first picture-group of 5 paros, none picture shows a paro we could assign to one of the described species. They are undescribed forms from other origins, probably peninsular Malaya.
The second 4 pictures show P. alfredi. I am shure the Sedili-Paro is an alfredi. The cf. alfredi “Mimbon 98” is i. m. o. P. alfredi too, but a little different in colouring and the larger lenght of fins and especially ventral-filaments. The other differences you mention Peter are variances or illusions (perspective). Nothing to do with food. The long filaments of alfredi “Mimbom98” in this stock have been very constant, like it is not so in alfredi Sedili-stock.
Now we know that the red pigments, which are put on a base of a reflecting tourquise zone, are very instable and depend on carotinoids food must contain (ore contains not). The red markings get their brightness from this iridescent base. All bright red coloured paros are concerned. If the red pigments are gone, a tourquoise colour appears.
The brownish-red colours of P. quindecim or linkei for example surprisingly are not.
Every species (tweediei, alfredi, rubrimontis, opallios and shurely the undescribed others too) should be very red in nature (all I cought). They loose the reed pigments by get fed with carotionless nutrition over long time. Since I feed them with beta-carotin-bostered grindal, I had this effect nevermore.
