This is what happens when you keep the brine shrimp too long:
So that's kinda what it looks like after 36 hours of starting the hatchery and then turning off the aerator. It was a pretty big disappointment when I couldn't find any viable brine shrimp to feed my hungry Betta fish with. Nevertheless, I have an alternate hatchery running and should have some brine shrimp ready for this afternoon. I'll just have to restart this hatchery and hope for the best by tomorrow.
So, as some of you may know, I have been keeping Betta Fish since the beginning of this school term (Spring 2010). I have had 2 batches of betta fry. The first died after I made some mistakes. The died within a week. The second batch is doing quite well. They are still doing fine and this is day 15 for them. I have had live plants in the tank, so when they first started out I didn't feed them brine shrimp until the 3rd or 4th day. Many of them couldn't eat it, but it was good for them to be curious about the brine shrimp. They started eating them by the 5th day, and I have been feeding them just the same ever since.
Brine Shrimp are annoying to hatch. I had to buy 4 soda bottles, salt, air pump, a light, and of course the eggs. The most difficult part about hatching them is learning to time it all out in advance. It takes 18-24 hours to hatch the brine shrimp, and they are only good for a day or less after they have hatched (in my experiences). Therefore, you must have an alternating hatchery so that you won't run out of food. I'm still trying to get the process down on when to start a new batch every day. Later, I'll add a link [here] to a Youtube video that I learned how to do this.
I'm really looking forward to the 4th week. From what I have seen on Youtube, they start to get larger. That's really a great thing, because I know during the 1st week I really had to strain my eyes in order to see them. After the 4th week, I'm going to have to learn the process of covering the tank with plastic wrap in order to prevent the fry from getting pneumonia. They start using their labyrinth during this time (5-7 weeks is what I read online).
With all that said, I currently have maybe 70 fry still thriving in my 20 gallon tank.
