Yellow shrimp, brown head?

[punchbuggy]

Hi All,

I noticed that my yellows after a period of hot days a few days ago and now cooler temps (the water went from normally 23 to 26 and now back to 22) The heads, especially the females, are turning "brownish" By heads I mean what we would say the brain would be located. Mind you as well, all of these females are also showing a saddle.

Is this normal mating behaviour? I have one berried already, but i never noticed the brown shading before.

I guess this would happen for cherrys and blues and what not as well.

Also a thought, could it be tht they are grazing on a lot of brown-looking algae/film?

yeah it's normal... i think their stomach is in the "head" region.

ah yup. i just looked up the anatomy. no more brown foods for them!
