Day 59, 26, 23.

I noticed today that a couple of the stage five zoeae aren’t orange like all the others have been, they’re an unusual blue (sort of grey-blue like an uncooked shrimp). In this picture, you can see the blue one above the two shells (center) and an orange one just to the right of the shells for comparison. Quite a difference. More than just a food thing (because they are all fed the same), I think this means that the last surprise spawn actually WAS from the small Ecuadorian that I saw near the pool (I adopted three late this summer and have been mostly leaving them alone so they could adjust to the new digs). I’m not prepared to call it as 100% an E, but I think this makes a lot of sense, especially given the level of cannibalism I’ve seen in this newer group. It’s off the charts—and they are fierce about it, too. Plus, many of the zoeae have been extremely fast and acrobatic in the wastewater when I try to put them back in the tank and many also haven’t colored up as quickly as the last batch. If so, I’m really stoked that this may be the case, but also worried for all the remaining PPs that are currently transitioning and getting eaten before I can even get to them to move them to safer waters. I probably lost several hundred today. Since they tend to transition first thing in the morning after I turn on the light and feed them, my new strategy is going to be trying to spot as many as I can (first thing in the morning) either pre-molt or mid-molt and move them over to the intermediate tank where they actually have sand and small shells to hide in while they harden up. Let’s hope it works.
