Ask About the Lid, Every Time, Without Exception
Ask whether the sitter will close and check the lid after every interaction with the tank, because zebra danios jump, and they jump most at feeding time and when startled by a shadow or a lifted lid. Find out whether they will feed through the smallest opening practical and look at the floor around the tank at each visit as a matter of routine. Ask what they would do if the count came up one short: search the floor and the filter area first, then call you. A sitter who has kept active fish before will treat these questions as normal; one who laughs them off will eventually lose you a fish through a gap you warned them about.
Ask How They Will Feed a School That Attacks Food
Ask the sitter to describe how they would feed zebra danios, because the surface explosion these fish produce convinces almost everyone that the portion was too small. Agree the pre-portioned amount, scattered along the tank so the whole school feeds rather than a knot at one end, and the firm rule that the show is what well-fed danios look like, not hunger. Ask whether they will remove any food still floating after a couple of minutes and note it, since this group's appetite is such a reliable gauge that uneaten food is itself a warning sign worth reporting the same day.
Ask How They Will Count Fish That Rarely Slow Down
Ask how the sitter plans to get an honest count, because zebra danios in full flow blur into stripes and are famously easy to miscount. The reliable moment is the first seconds of feeding, when the school rises and bunches in open water. Ask whether they will count then, count again, and report the number they actually got rather than the number they expected. Show them the group's size and its usual split, since danios often run in a main school with a couple of fish working the far end, which a new eye reads as strays or missing fish.
Ask About Heat, Flow, and Summer Absences
Ask what the sitter would do on a hot day, because zebra danios come from moving, well-oxygenated water and a warm, still tank is where their hardiness runs out. Agree the signs to watch: the school hanging at the surface, faster gill movement, or fish going quiet in the flow. Ask whether they will check the thermometer at every visit, keep the filter outlet running as set so the surface stays broken and moving, and call you before improvising with ice, open lids, or cold water changes. Improvised cooling shocks fish; a phone call never does.
Ask What 'Normal' Looks Like for This School
Ask the sitter to tell you back what this zebra danio school does on an ordinary day, because absence cover fails when every behaviour looks alarming or nothing does. Cover the constant motion, the chasing that is hierarchy rather than injury, the brief rests in the current, and the way the group tightens when someone approaches the glass. Ask them to flag the genuine changes instead: one fish unable to keep up, a danio sitting on the bottom, torn fins spreading through the group, or the whole school refusing food. Those specifics, agreed in advance, turn a nervous sitter into a useful pair of eyes.
Run One Visit at Full Speed Before You Go
Have the sitter do a complete visit while you watch from another room, because zebra danio care is a performance task: lid, portion, scatter, count, note, lid again. Review the message they send you as a trial update and ask whether it would tell you what you need if you were already travelling. Fix the routine where their version and yours differ. With that rehearsal complete, KinsLe Care Pass gives your sitter temporary access to this school's routine and key tank details for the length of your trip.
