It really depends on the setups, and the estimated time with this job , how replaceable the fish are, other people in the household and the availibility of new homes..
Is this a temp job or a longterm job?. If this is planned to be a temp situation, then possibly ride it out. If it's planned to be long term, it may be better to attempt to re -home the fish. Of course if there are no new homes, this option may be eliminated.
How much attention do the setups require?, any special feeding or water requirements?, are these fish that have routine emergencies?. Fish that need specialized or emergency care are not going to last long when attention and care is reduced.
Are there other people in the household willing to do at least basic checks and call when something is wrong?.
This situation sounds a lot like boarding.
Given the experiences I have with boarding, I find it a compromised situation. especially if you live alone or nobody is checking on the fish care.
For boarding situations, you need good solid setups that are setup for low care.
You need to prevent emergencies from happening as much as possible. In the end you'll have to accept your fish will probably eventually be lost to something preventable because you were not home to correct it.
Also, if you will be at work more then home, why not move your tanks there where they'll get more attention?...Just a thought.
