I have even accidentally moved fry trapped in the brine shrimp net to little bowls of water when I am collecting larva and find them weeks later-fine and grown getting mass water changes from rain since the bowl was under the drip line of the house....
If your 10gal tank is full to the top...add a second female and see if that will help and stop changing the water-just top off and don't let it get too much direct sun-cover the top if needed with slats so you get shade but good air circulation and use floating plants like water lettuce....Let it get so dark you can't see in it-add more oak leaf and some live plants to float...also allow some of the leaves to float on top for the male to nest under-mine seem to like the dark brown leaves better than the yellow leaves.
Usually its the barometric pressure they are responding to with the storms
I like to use a brine shrimp net for my microworms-they will slowly work their way through it for the fry to eat, but personally I like newly hatched BBS.
Love to see some pics....
Thanks for your input.
I have about 30 oak leaves in the tank. The water is pretty dark. just before I went to bed I was thinking of going to Michael's to look at the possible materials I could use to filter the worms. When I woke up I had the idea of using silk. Pretty much like the brine shrimp netting. Perhaps if i can't find any silk I will test the brine shrimp net I have and possible sacrifice one since they aren't too expensive.
I have been trying to decap Brine shrimp eggs and then hatching without salt. I found an article online where a guy hatched this way just using baking soda. So far no success. perhaps I needed a heater or a higher PH. It was my hope I could introduce the eggs hatched without salt into the tank and the bbs would be able to live in the tank with the spawn and get eaten as needed. lol
I am pondering a way of modifying a tank to be able to create artificial low pressure to trigger spawning.
