Blue Gularis -Reply
I am not an expert on Blue Gularis. Bob S. on killietalk should really be the
one to answer this as he is much better. Most people have bad luck
water incubating gularis eggs encountering a 50% or more fungus rate. If
you water incubate you can expect the fish to hatch in three weeks at
75F. In water incubation the fish lay their eggs in mops and the hand
picked eggs are kept in a dark container and the fungused eggs removed
frequently. You must also change the water a couple of times.
If I hand pick the eggs I place them in a petri dish with clean water of
similar temperature and chemistry as the parents. I add 1 drop of
methylene blue. 10 minutes later I drain off the water and replace it with
fresh water. The bad eggs will be a different color than the good eggs. I
then add 1 drop of acriflavine and store the eggs in a dark place for a
week. After a week I remove the bad eggs, change the water and add
fresh water only no chemicals. Fish should begin eyeing up soon.
To peat incubate blue gularis you place a bowl with peat moss in the tank
and let the fish spawn there. After a week, remove the peat and place it
in a big brine shrimp net and rinse with fresh water. Then spread the peat
out to dry. As soon as the edges turn from brown to gray bag up the peat
in a plastic bag. This peat dryness is referred to by killie members as
Langton #2 in honor of Roger Langton and an excellent article he wrote
about drying peat. I like to fluff up the peat and fill the bag with air, then
seal. Keep dark. Should hatch in six weeks. So in about 5-7 weeks place
the peat in water and the fry should hatch out over the next week.
Several articles have been written about spawning blue gularis and if you
are not an AKA member I would suggest joining and then asking the library
committee for back articles on spawning gularis. I especially remember
several very good ones about continuous set-ups.
I use a combination of the above methods. I spawn my killies over mops
but instead of picking eggs I just bag the eggs up in plastic bags.
Sometimes I add a pinch of peat moss. After 4 weeks I take the mop out
of the bag and place it in a one gallon jar with a lot of aeration. A week
later I turn off the air. The next day the eggs hatch. I have been told that
the increase in carbon dioxide either makes their shells weaker or scares
them into hatching out for air. Who knows.
I have sold out of most of my killies but should have some more for sale
next month, including eggs of blue gularis. Best Wishes Bob
