update! they both seem to be doing really well this morning, swimming around, and giving me the "this is not bloodworms" face when I give them pellets, lol. for right now I'm calling the first one gray and the second one stripey, just to make it easier to differentiate between the 2 when I talk about them
Gray's looking like he has a bit more color already, and seemed to be a bit upset that I was looking in at him instead of immediately feeding him, lol

Stripey is almost constantly moving which makes taking pics difficult, lol. Stripey does seem to be a bit less stripey today, lol

right now they're in bare qt containers for treatment, but I'm thinking of getting some little rocks or marbles or something to put in there, just to give them something to look at because they both seem pretty curious
