Ugh. I don’t even know where to start. Was feeling so good about everything yesterday when I closed the door and turned off the light at 8pm. Woke up at 3:30 am and couldn’t get back to sleep for thinking of all the things I have to accomplish and how I might do that. Finally got back to sleep sometime after 5, then overslept and didn’t start the first water change until 8:15. Went to light up the newly hatched brine shrimp only to discover that somehow the air pump had gotten knocked last night and stopped working–lots of brine shrimp, but all dead and already stinky. Couldn’t feed those and that is currently the only thing the zoeae are reliably eating–probably because they are such killing machines they like their food alive and kicking.
The later water change (from oversleeping) meant that at least 300 megalopa were already dead because they had morphed and gotten killed by the blue stage-five zoeae while I wasn’t there to intervene. SO. MUCH. CARNAGE.
And they aren’t just killing for eating anymore, it’s clear, They target them and dispatch them quickly. it’s just straight up killing. I think it’s a resource competition thing…or the fact that once the megalopa harden up, THEY start to kill the zoeae. I don’t believe in an ONLY competitive model of animal survival (cooperation is seen a lot, too, just not generally in babies). When it comes to babies of any species, that selfish gene rules the day. Babies will do anything to outcompete their siblings because it really is a matter of life and death. And these zoeae aren’t even siblings of the PPs (I don’t think–still pretty convinced they’re Es). But I think they are “smart” enough (in a selfish gene sense) to know that it’s kill now or be killed later, so they are killing now with a vengeance.
And the carnage isn’t even the problem. per se–there are still tons of zoeae, and truthfully I couldn’t handle 300 more megalopa right now. I’m already incredibly overwhelmed just by the ones I’ve managed to save. BUT once dead, the carcasses foul the water quickly and then more die just from the fouled water. OR I work my butt off changing the water SO MANY TIMES …you get the idea. Woe is me.
Threw out my back around 9am–putting on a sock. How does that even happen? That made the water changes even more fun.
Had a 10:30 appointment for my back that I barely made after the carnage. Got home around 12:30 and got right back into it only to have more catastrophes. I’m too tired to relate that whole story (still ongoing), but suffice it to say that the transition tank collapsed, creating an IMMEDIATE emergency with no quick solution. So exhausting, so nerve wracking. I’m getting tired of continually being forced to think on my feet and avert disaster. And sadly it wasn’t entirely averted, but I did my best. I sure hope we have some left come morning, but I am absolutely burned out. Hopefully the backup brine shrimp will start hatching soon.
I figured out comments! Have at it.
