Bloodworms have pigment from other group - hemoglobin. Hemoglobin is metabolized at the digestion and I am not sure if it may have influence on eggs color.
BTW - Hemoglobin lets bloodworms live in very polluted water.

There is very much fat in eggs and so eggs color is strongly dependent on diet.
Pigments dissolved in fat (lipochroms: red - carotens and lycopens, yellow - xanthophyll) migrate from food to eggs practically not changed.

No - I catch plankton in natural reservoir. Therefore from April to November - during winter it is to cold to dabble :wink: . But this year it is so warmly that last Sunday I caught a portion:

Generally you are right: higher conductivity has negative influence on spawning of blackwater species, but we should be aware of fact where this higher conductivity comes from. When conductivity is a result of "mineral" ions concentration, it may affect the successful spawning, but when it is a...
Mike - what wrong is in higher conductivity? This conductivity originate from ions H+ (and Cl-) and (I suppose) is harmless for fishes. When pH is droping from 8 to 6 concentration of ions H+ is rising 100 times.
The conductivity originating form "mineral" ions: Na+, K+, Ca++, Mg++ is harmful...
Ask - I'll answer if I can.
I use granulated peat, but not to much - 200ml [12inch^3 - I'm not sure what unit would be best in US :-) ] 1 time/~3months.

Thanks
pH~6, GH <1dH, KH <1dH, T 25-26C [75-77F] (june/july ~28C [83F]). Water 100% RO.
This was first time. Tank 50x40x35cm [20x16x14"]. No other fishes. Water changes - weekly 20-25%. Lots of java-moss, a bit of algae ;-).
Juveniles ~1month
~2months 10-12mm [0.4-0.5"]
~2,5months...
