A healthy aquarium is a balanced one — water chemistry, filtration, stocking and feeding all work together, and most fish problems start with the water.

Start the file with the shoal size, source, and an arrival photo noting how red each rummy-nose tetra's nose looks, because that colour is a living water-quality gauge for this species. Log temperature, pH, ammonia, nitrite, and nitrate from day one, and keep dated notes on schooling behaviour, feeding response, and…
Record the pearl gourami's sex if you can tell it, its size and source, and a clear photo of the pearly spotting and throat colour on arrival. Note tank mates, plant cover, surface access for this air-breathing labyrinth fish, and starting temperature and water test results, then log appetite, fin condition, and any…
Start with the group size, source, and a daytime photo, even though kuhli loaches hide at first, because you need a baseline count for a fish you may not see for days. Record substrate type and depth, every cave and leaf-litter area, the lid fit, and starting water results, then add dated night checks noting how many…
Begin by recording the full shoal size, because harlequin rasboras should live in a group and losses change their behaviour, plus the source, arrival date, and starting water results. These fish favour soft, slightly acidic water, so log pH and temperature alongside ammonia, nitrite, and nitrate, and add dated notes…
On day one, note each guppy's sex, colour pattern and strain if known, where they came from, and how many males and females you added, because that ratio shapes stress and breeding from the start. Record tank size, temperature, water test results, and every tank mate, then keep a running line for fry appearances and…
From the first day, record where your goldfish came from, its variety and size, the tank volume and filter, and your starting water test results for ammonia, nitrite, nitrate, and temperature. Add feeding amounts, water-change dates, and dated photos, because a goldfish that looks fine today can show stunted growth or…
Start corydoras records with the species and number in the group, the source, individual markings, the substrate they landed on, and your first temperature and test readings. Build the log around sinking foods and what reaches the bottom, barbel condition, group resting spots, water changes, and growth, because…
Begin clown killifish records with the number and sex of the fish, the source, the lid and floating-plant setup they entered, and photographs of the males' striped patterning once settled. Because these surface dwellers jump, log the tank's cover arrangement and any gap you seal, alongside temperature, test results,…
Open celestial pearl danio records with the group size, the sex mix as far as you can judge it, the shop details, and photographs taken once the fish have coloured up after settling, because newly moved danios look washed out. Log temperature, test results, water changes, and the fine foods you offer, then follow…
Start bumblebee goby records with the number you bought, where they came from, individual banding photos, and most importantly the exact water they were kept in, including whether the shop held them in fresh or brackish conditions. Log salinity checks if your setup uses them, temperature, foods offered and accepted,…
Begin bristlenose pleco records with the fish's size, colour form, sex if the bristles give it away, where it came from, and a photo of its underside pattern if you can get one during acclimation. Log the driftwood in the tank, the vegetables and wafers you offer and what actually gets eaten overnight, water readings,…
Record the whole school, not a single fish: how many boesemani rainbowfish you bought, their sizes and sex mix if you can tell, the shop they came from, and a group photo before colours develop. Log tank temperature, test results, water changes, and foods, then track male colour and morning display behaviour as the…
Start a betta record on day one with the source and arrival details, a clear side-on photo, your tank's temperature and test results, and the exact foods and amounts you settle on during the first fortnight. Keep logging fin condition, appetite, activity, water changes, and any equipment swaps, because a lone betta's…
Share the one fact that surprises most sitters first: your white cloud mountain minnows thrive in cooler water, so the absence of a heater or a lower thermometer reading is intentional, not a fault to fix. Add the size of the school, the small foods you rotate, your water-change routine, and how active and bright the…
Tell a guppy carer the sex mix and head count, because a tank that starts with a few females can quietly gain fry while you are away, and note where newborn fry hide and that they should simply be left alone. Add the small measured feeds, your temperature and water-change routine, and which males or females you are…
Give a goldfish carer measured feeding amounts first, because overfeeding is the fastest way a helpful sitter fouls the water, then add your tank or pond temperature range, filter routine, and your normal generous water-change schedule with the exact conditioner amount. Explain that a goldfish who begs is not a hungry…
Tell a new corydoras carer how many fish are in the group, what sinking food they get and when, and that these bottom dwellers need food that actually reaches the substrate after the lights dim. Add your tank temperature, your usual water-change routine, and a note that intact whisker-like barbels and active snuffling…
Share stability above all else: your cherry shrimp tank's current temperature and test results, how much and how often you feed, and a clear warning that big water changes, sprays, and copper-based products near the tank can harm the colony. Leave notes on molting, because a pale empty shell on the substrate is normal…
Share your betta's exact feeding amount and schedule first, stressing that he must not be fed extra, then the heater and filter routine, water change pattern and the signs that mean call you at once. Tell the carer the tank lid stays closed, no other fish or cleaning sprays are introduced, and what his normal flaring,…
Give your white cloud mountain minnows one tank folder with sections for the shoal's purchase record, cool-water tank and flow equipment, water test sheets, feeding notes and dated behaviour pages. File a short description of the tank's usual temperature range and current setup at the front, since visiting helpers…
File guppy paperwork by tank rather than by fish, with sections for the founding group's purchase record, equipment and plant details, water test sheets, a population log and the feeding routine. Add a dated line whenever fry are moved, sold or given away, because an unrecorded population change makes later water…
Set up a goldfish folder with sections for identity and purchase, tank or pond and filtration details, equipment receipts, water test history and a growth plus feeding record. Goldfish live a long time and often move to bigger housing, so file each upgrade with its date and keep photographs that show size against a…
Create one folder for your corydoras shoal with sections for purchase records by group, tank and substrate details, equipment receipts, water test sheets and feeding plus behaviour notes. Add a front page listing how many corydoras you keep and their usual resting and feeding spots, because that summary is what a new…
Use one folder per celestial pearl danio tank with sections for the group's arrival record, nano tank equipment details, water test sheets, feeding notes and dated observation pages. Because these fish are tiny and shy, file a short note on planting and hiding places with the routine page so a helper understands why…
