Propinqua: New arrivals came in today. They are acclimating to their tank as I type.
Ninja Zoea: Quite a few zoea still with me. Fed them a mix of Spriulina and Golden Pearls. I'll add a little phyto later on as well. I'm doing something a little different with these guys by attempting to offer the GPs at an earlier age. Just a small fraction so not too bad.
Amano Zoea: Captured one more shrimpet and will try to catch it up to the others that started upstream yesterday. The salinity isn't too far off but have to be very carefull about it. There is one more free floater in the tank. Once he/she morphs that will be a wrap for that test.
Now the fun stuffs...
While mixing the feed for the Ninja zoea (I use fresh salt water for this), I had to restart the syphon in the jug. When I noticed it starting to flow, I fumbled a bit in trying to shut the valve. I was doing this over the tank hold the expecting Amano female. I wound dripping about 1-2ml of salt water in her tank. I then moved the tubing and wound up putting about the same amount in the tank with the expecting Ninja mother! Drat!!!! Very, very small amount so not overly concerned with it.
Fed the Ninja zoea and immediately performed water changes on both the tanks. I'm slowly driping in new water. Just went down to check on things and the water level is perfect for Mrs. Amano and move the tube over to the Ninja lady. I then go and check the Oto tanks for few minutes. Go back to check on the Amano lady and find her water has gotten really cloudy. What in the world??? Closer exam....HATCHLINGS! We have zoea. And a ton of them to boot. Awesome deal. She still has a ton of eggs in her carriage so this is going to be a very large group to work with.
Disaster! Went to turn out the lights and found both females dead! WOW! Unreal! Don't know what to say. Hard to believe that that little amount of salt would have caused that. I'm simply speechless at the moment.
Lights on this morn and all is well in zoea land. All of the new Amano zoea perked right up and hit the jet stream (a.k.a current via bubblers ). They will be washed out to sea today. Amano shrimplets doing fine so far on their journey upstream. Another salinity change in order for today.
I saw a berried Amano lady in the main tank that looks like she is close to hatching out. Not sure how I missed her. I'll try and get her moved as well...very, very carefully.
Last nights disaster has definately motivated me to push to get the rack complete. Should have and would have been prevented with better management. I'll be tied up Saturday so will really hit it hard on Sunday. I'll get the tank that had the Ninja lady in it cleaned out and move another female over. No telling how far I would be in this project if I factor out the human error piece of it. I've got some big plans that will aid in the management of these tanks which will mean less "hands on" and will greatly reduce the possibily of error.
Newest batch of Amano zoea being washed out to sea. This will be the second time I use an airstone. It is in combination with a bubbler. So far it has really kept the current nice without being rough on them. Fed about 1.5ml of phyto. Still have the one remaining free floater. I lost one of the Amano shrimpets. Seems getting them back to fresh will be just as challenging. The air is a little different in the tank so less oxygenation. May be a factor but then again, the other still looks good.
Bad news on the Propinqua front. Most of the ones I just got yesterday have already expired. So not happy with this. Guess the trip was hard on them only thing I can think of being that they went into a well established tank with Props already living in there.
Cleaned out the old Ninja tank and gently moved the other expecting Amano in there. She was very easy to catch. Now the question will be if she will drop any eggs from the transfer or not. Preferrably not. Not sure how far along she is but looks like they could hatch very soon.
