Don't beat yourself up over it. Hopefully he pulls through. They're always a bit timid at first anyways. Both mine hid for the first week or so Before they became very active. As long as you're keeping the water safe for him, that's the best you can do. I'd suggest you also go pick up the API master test kit, it's a liquid test kit that will out last and out perform the test strips. Just so you can be sure of the water parameters at all times. It's one of the best investments I've made since I started.
