How long has your flasher gone missing?

[Cubbies]

I bought a blue flasher 7 days ago. I didn't see it till 2 days after when I fed. I haven't seen him since then. I have lids on the tank and still check daily the outside with nothing. I had a filamented before and he was a scardy cat for about 2 months till he decided to fully come out. Thoughts?

So 5 days without a sighting? I would not worry yet, my Bell's hid for about a week one time. Scared the heck out of me but he came out and is just fine.
