Activity and numbers come first for guppies
A guppy carer should start each visit watching the whole tank, because guppies normally fill every level with movement, males displaying to females and the group surging to the surface at any hint of food. A guppy hanging alone at the surface, hiding in plants all visit or shimmying in place stands out against that usual energy and should be reported to you the same day, with a note of whether it ate.
Numbers matter with guppies because a dead fish in a warm, small tank spoils water quickly. The carer should do a calm count against the number you wrote down, check behind the filter and inside decorations where a body can lodge, and remove any dead fish with a net, noting the time. If you have fry in a breeding net or planted nursery corner, the carer also confirms the fry are moving and the net or plant cover is undisturbed, without trying to count every baby.
Heater, filter and the warm-tank routine
Guppies are tropical, so the daily equipment check for a guppy tank centres on warmth: thermometer within the range on your note, heater light cycling as usual, and filter flowing without rattling or slowing. A cold snap in the house shows up in a small guppy tank within hours, and the carer should message you if the reading falls rather than adding warm water from a kettle, which swings temperature dangerously.
The carer also checks the water level, since evaporation leaves filter outlets splashing and concentrates waste, and tops up only with the prepared water you labelled, if you left any. Surface scum, cloudy water or a sweet, stale smell at the lid are reportable changes. Lights should follow their timer, giving the guppies a real night; a light left on around the clock by a timer fault stresses the group and feeds algae.
Feeding beggars without overfeeding them
No holiday instruction matters more for guppies than the food portion, because these fish act starved minutes after a full feed and a kind carer will believe them. Leave each day's flake or micro pellet ration in a labelled pot and state plainly that one pot is the whole day's food, however eagerly the group crowds the glass. Uneaten food on the gravel means the next day's pot still stays the same size and you get a note about it.
The carer should scatter the portion across the surface so smaller females and young fish feed alongside assertive males, then watch for two minutes to confirm everyone eats. Guppy water quality collapses from kindness more often than from neglect.
Females, fry and the social balance
A guppy carer should also keep a light eye on the group's social picture, because a male relentlessly chasing one female or a female isolating herself near the heater can signal trouble brewing while you are away. If you have a heavily pregnant female, tell the carer beforehand that births may happen, that fry hiding in plants is expected, and that no rescue operation with nets and boxes is needed or wanted.
The carer must not separate fish, add a breeding trap or move a female mid-holiday on their own judgement. Observations go to you; interventions wait for your reply unless a fish is plainly suffering and you have agreed in advance what the carer may do, in which case your written note beside the tank governs.
The daily message that keeps you in touch
Close each visit with a short report to you: activity, count, temperature, filter, food given and anything odd, sent the same day rather than bundled at the end of the holiday. A quick phone photo from the front every other day lets you see colour, clarity and plant growth for yourself and reassures the carer that their work is being seen.
