No specific holidays that I'm aware of, although as long as you call at least a day before, we can usually schedule something around our service calls and livestock pickup.
As far as the corys go - those were the last of those C. paleatus I'm afraid. Plenty of c. habrosus left. I'll be getting more paleatus in but I'm picky about my cory sources so I'm not sure if it will be "soon" -- I'd rather have no cory's than crappy ones.
ps - I will NOT be in the shop this weekend, but we should be getting some new plants in on Friday. The list includes:
Anubias sp 'nana'
Dwarf baby tears on rock
Tropica sword (Echinodorus parviflorus 'Tropica')
Pygmy chain sword ( Echinodorus tenellus)
I'll update things once I get the order unpacked and settled in.
I also put away some nice dwarf lily plants last week.
