I have gotten further than last time.
The fry are about two weeks old now. I am pretty sure they were all dead by now last year. It's hard to count them because they are small and spread out and sometimes hiding but I see approx 100-200 still alive in the 60 gallon aquarium. There may be/should be a few hundred still alive in the greenwater tank too. They are 3-4x the size from the newborn. I would say they are about the size of newborn tilapia which are able to eat powdered commercial food, so i have started crushing up a couple of pellets to see if they will try to eat it. If they are i cant tell. I have to be careful because it's hard to vacuum with so many tiny fish and I have to worry about fouling the water more than it already is.
My daphnia, fairyshrimp and clamshrimp hatch attempt seems to have failed so i dont have bigger zooplankton to feed them. They are going to have to eat chunks of algae or powdered food to sustain themselves in the interim if they are going to survive.
These pictures are from last friday so they are about 4 days old.
The green water was still very green.. But now the green water is clearing up. I started a second ibc about a week after the first so i should still have green water for a few more days. From my understanding you cant keep green water going indefinitely. Oddly enough The algae produce an enzyme that will inhibit algae growth. I will end up discharging this water into my aquaponics system as evaporation and transpiration calls for top-ups. I *think* i will have to collect new rain water or treat some municipal water to start a new one.
I dont know if these are some kind of mayflies or mosquitoes or what, but they think they can land on the water but they find that the air stone causes no surface tension and instead of landing, they dive and they drown.
It's possible to see the fry now but still cant get a good picture. The spots i circled show dark spots which are mostly fry.
I am optimistic i will get 100 or so to live this time. I am still learning a lot and there's a few changes i will make to my process the next time i get a spawn.
