Day 4 and I'm down to about 20. I no longer have to add rotifers since they are reproducing faster than they are being eaten, I believe that is due to the dwindling population of fry. I am continuing to add the oto a but there isn't too much interest just yet. I'm experiencing more losses than I would have though so I'm stepping up my water changes today in hopes that that will curb the death toll. The first few days I did a few small water changes, basically just replacing what ever water was lost due to syphoning out the dead fry about 32-48oz. Today I'm basically doing water changes all day. I'm removing about 16oz at a time and slow dripping it back in. When I notice the cup is empty I'll repeat the process. I've done about 48oz so far. I've also noticed that the fry are less active when the water is clearer. A couple times after I've come home to find the water has cleared up the fry are at the bottom and along the sides. When I tint the water they swim around more. Not sure if letting the water clear up too much might be responsible for some of the deaths. My ammonia alert badge is still reading safe and I also added a few drops of prime on the evening of day 2. I'm not keeping notes, though I should, other than what I post on here so I'm keeping track of everything I've done to help out with the next clutch.
The last time my picassos took 12 days before laying the next clutch with means they should have laid yesterday. The female is absolutely huge so I'd be surprised if she didn't lay today. They are spending a lot of time in the pot so we'll see. They have always laid in the same pot but this time I've switched it out when I pulled the pot to hatch, I wonder if that is the reason for the delay?
In other news my snow onyx pair have been showing some serious nesting behavior. I even saw the male taking a few practice passes. I've read that if you have multiple pairs in one system and one pair is breeding that the others will pick up on it and start breeding too. I guess we'll see if there is any truth to that.
