holiday advice

I'm going away for 4-5 days; I have no worries about what to do with the
coldwater tank but the tropicals have me a little puzzled.

the other half will be busy and anyway I don't want to ask him to feed
them more than once daily as I'm a little scared he'll overfeed, so
would it be a good idea to take the temp down a degree?

there is a dwarf gourami, five black kuhlis and seven harlequins (one of
whom is about to be the subject of another post). The current temp. is
24degress.
