Originally I Put 10 down for cories(started with 15 a few years ago) but after watching the tank for a few hours, I could only verify 7 cories. So that's 17-3.
At the posting time I thought my albino rainbow shark had passed... but he's still alive so, 14+1. I also cleaned my mini pond outside and found 6 Rosy Reds still alive. 15+6= 21
