I have a Sterbai Cory fry in a 2l hang on breeder box that must be about 5/6 weeks old now. I am off on a city break which seems to extended from three to six days. I have no issues leaving the tank and inhabitants for that long but not sure about the fry. I am currently still feeding them LiquiFry with the odd crumb of sinking tablet but not sure they can go that long? The two people I would normally ask to pop in are both away at the same time. Do you think they will be OK for that period of time (there is a flow of water from the main tank into the breeder box and there is also an air stone in there) or do I need to see if I can get the in-laws around to stick a drop of LiquiFry in?
