I'll definitely have to try that pea thing--is it okay if I freeze canned peas or do I have to buy them already frozen? I know that sounds dumb, but I dunno if there's something in frozen peas that makes them special, hehe...
Okay, my water results are as follows:
Ammonia: 0 ppm
Nitrate: 10 ppm
Also, the angelfish appears to not be freaking out as much, though he does still have a bump or two (albeit in different places than before) and the little flecks of ick on his fins and tail are still there. The only other fish acting noticeably is the phantom tetra--he keeps staying in one place and sort of twitching. He'll swim around for a bit but more often than not he'll be swimming in place.
