how often should adf surface for air?

[mpmistr]

I'm a bit concerned because I've not seen my frog surface once in 6 hrs.
He spends most his time hiding in the ornament

Well, I doubt you've stared at your aquarium for 6 hours straight.

Honestly though go check on him, I am pretty sure after 6 hours he surfaced and you didn't see him do it.

I think how often they go for air is relative to how active they are. Like when my ACF are swimming around a lot, they breathe more, when they're being lazy, they don't need to get air very often.

Side note: Do check and make sure he's not trapped.. they can easily get trapped under ornaments and drown.
