The critters in the bowl are now about 2mm long, I can clearly see that at least one is a fairy shrimp and the others are triops, they already look like miniature versions of the adults!

I'm going to try to clean out their bowl and do a small water change with water from the tank today.
Speaking of the tank, I got two moss balls and a snail. The moss balls actually seemed to make the tank water clear up a bunch and the snail is happy and active. I'll probably still need to do a 25% water change on the main tank soon since it has no filter and all.

I don't know whether to be proud of myself for being so responsible about taking care of my pets or sad that it's one of the only things in my life that I'm responsible about.
