Start the note with how a pleco lives
Written instructions for a bristlenose pleco should open with the fish's daily pattern, because everything else follows from it. A bristlenose spends daylight hours wedged in a cave, under driftwood, or behind the filter, then emerges at dusk to graze algae, rasp on wood, and patrol the glass. A sitter who does not know this will report a missing fish on day one. State where its favourite hide sits, roughly when it appears, and that seeing only a tail or a whiskered snout at midday is a perfectly good sighting. If a male is guarding eggs inside a cave, that fact goes at the very top in capitals: the cave is not to be moved, lifted, or peered into with a torch.
The feeding paragraph, in portions
The feeding section of a bristlenose pleco note must be measured, because good intentions overfeed this fish fastest. Bristlenoses need more than tank algae: the instructions should specify a sinking algae wafer or pleco pellet on set evenings, pre-counted into containers, plus a piece of blanched courgette or similar vegetable clipped or weighed down once or twice during the trip. Uneaten vegetable comes out the following morning before it clouds the water — write that removal step explicitly, since sitters often assume vegetables can stay. Warn against feeding at midday out of sympathy; food dropped for a sleeping pleco feeds the filter bacteria and little else.
Driftwood, caves, and the no-rearranging rule
Habitat instructions for a bristlenose pleco protect its furniture. Driftwood is not decoration for this species — rasping wood forms part of its grazing — so the note should forbid removing, scrubbing, or repositioning the wood and caves during the holiday. The sitter's decor duties are limited to confirming nothing has toppled onto a hide entrance and that the pleco's usual cave remains shaded. If eggs or fry appear in the cave, the instruction is simple: leave everything exactly as it is and message the owner a photo. Rearranged aquascapes stress a pleco far more than a week of slightly untidy plants ever will.
Waste, water, and filter notes
Waste management deserves its own paragraph in a bristlenose pleco note. This compact fish produces long, conspicuous waste trails and loads a filter more heavily than its size suggests, so the owner should complete a water change and gravel vacuum before leaving and write the sitter a short list of observations: filter running, water level steady, no sour smell. Topping up evaporation with conditioned water is the only water task to delegate. If the water clouds or the filter stops, the sitter calls the owner rather than attempting a water change with unfamiliar equipment and buckets in someone else's home.
What the sitter should report
Reporting instructions for a bristlenose pleco focus on a few clear triggers. A pleco that has not touched its wafer across two evenings, shows a sunken belly, pale patches, or shredded fins, or is found outside its hide in daylight looking listless should be reported the same day, with a photo if possible. Contact details in the note should run owner first, then a knowledgeable local fish shop or aquatic vet for genuine emergencies such as multiple fish deaths. End the note with thanks and permission to do less rather than more — for a pleco, restraint is care. Stored in a KinsLe Care Pass, these bristlenose instructions give your sitter temporary access to the routine, so the wafer schedule and cave rules survive even if the paper note goes missing.
