Re: Hatch rates

  Hi Patrick,

  Many thank for the good advice.

  Just  a few quick points of clarification-

  When you say "aged" water, are you speaking about water from the original tank, or water that has been treated separately.   Is it better to use RO water, or the treated water used in the killi tanks?

  Do you add ANYTHING to the hatch water?      I could see where the breeding mops would protect the eggs from light, thereby reducing the need for chemicals.      So scratch the acriflavine, but is blue still helpful?

  I will also try the peat method to see which is more successful, however I like the idea of swapping out the mops to reduce time in removing eggs.   Good suggestion for those short on time! 

  Thanks again and best regards,
  John

    Hello again,

    I have numerous eggs, but have had extreme difficulty in hatching them out.     Most are FP's, and I have been using moderate amounts of acriflavine and methyl blue in shallow water, but to no avail.

    Any ideas on how to improve hatch rates?      The only real luck I have had is to let the eggs hatch in the tanks, then removing the fry.      This does not appear to be a best practice, but it is at least effective.   I wonder if I have been wasting my time removing the eggs and placing them in petri dishes.

    The survival rate also seems to be better in the tanks than in the "dishpans."     On those few occasions where fry have hatched, they never last longer than a few weeks.

    If anyone has any helpful hints, I am all ears.

    Many thanks for the help.

    John
