So over a year ago(like a year and a half?) I got cultures of vinegar eels and microworms to try feeding the bettas to see if that would help the sick ones I kept getting to be stronger and such. Well, I completely forgot I had the vinegar eels. Like after I set them up in their neat 2 litre with apples and vinegar, I just forgot I owned them(I put them in a cabinet, pretty sure that's why). I just re-found that 2 litre today. And guess what! Not only are they still alive, they're big enough that I could totally pick them up with tweezers and feed them to my fish.
How creepy is that? Also, you can totally see their innards. Like plastic worms or something. Tempted to see how they fair against my usually ravenous betta boys and girl. O.o
