The difference is easy: Hard ice cream comes in turtle cheesecake flavour and not soft. That's all you need to know.
Hodor is still on the missing list. I will do a another sweep Monday to look for him. Meanwhile I see there's a really big fast pond snail in the 5g. He better not lay eggs. There's enough algae in there to feed a vegetarian lion :/ And it's mostly on the back wall under the filter output which I planted plants in front of so I don't have to look at it. The Great Wall of Pond Snails.
