My wife's got a bearded growler.
The man in the pet shop said they'd grow no bigger than a carp. Costing me a bloody fortune in krill so far plus I haven't seen one of my mates for weeks since she went to feed the buggers
Barrel,cute now but like you say can grow to twenty inches and live over 15/20 years !
You should have saved your money.
They don't eat krill
Not a bearded clam
It is growing some ginger fuzz now, though, and I'm wondering if the pet shop shaved him.
