When the colours are a little bit washed out you dont always see the black at the head clearly.
I have very white sand.
I am sure they are Winemilleri.
The only question is what is the little guy at the first three pics.
I know this is question is off topic, but how about a good pic of that pleco photo-bombing pics one, two and three? Looks like a L025? Fin colors are great!
