Out of curiosity, how long can a
betta go without access to the air at the top of the tank?
Only, I'm sure I read somewhere that they do actually sleep? I stayed at my mum's last night, popped round on my way to work to give Hamish his breakfast (so spoilt!!) and he was lying at the bottom of his tank - soon as I put the light on he flew up so I assume he was resting/sleeping as it was dark.
How long can he do this for then without grabbing air from the top?
First time I've caught him sleeping! I guess where I wasn't there he was having a bit of a lie in!
