3,895 answers about fish & aquatics
A healthy aquarium is a balanced one — water chemistry, filtration, stocking and feeding all work together, and most fish problems start with the water. This page gathers the fish and aquatics library of KinsLe Answers in one place, organized by topic for freshwater and saltwater keepers alike. Every answer is original, written by KinsLe, and tied to a real KinsLe feature.

Photograph the tank from the same spot, at the same time of day, with the room dark and the tank lights on, and file each shot with a short note of what changed since the last one. A fixed viewpoint turns snapshots into evidence: plant growth, algae creep and a layout slowly sliding out of balance all become visible…
Hand over the tank the way you would want to receive it: the stock list with ages, the water targets and recent test results, the feeding and maintenance routine, the equipment's age and condition, and an honest note of any illness the tank has seen. Put it in writing rather than running through it on the doorstep,…
Give every tank its own profile in one shared place, and fill each with the same set of facts: who lives there, the target temperature and pH, the feeding routine, the equipment fitted, and the maintenance rhythm that tank runs on. One profile per tank, never one page for the whole fish room, is what stops a water…
For nerite snails, log the results that decide shell health and survival: ammonia, nitrite and nitrate, pH, temperature, and general and carbonate hardness, plus a copper reading any time you add something new to the tank. Nerites need alkaline, mineral-rich water - a pH above 7 with real hardness - because acidic or…
For Bolivian rams, log ammonia, nitrite, nitrate, pH, temperature and, because these soft-water cichlids are sensitive to hardness swings, GH and KH if your kit measures them. Ammonia and nitrite should be zero, and the real value of the log for rams is stability: small, steady numbers matter more than chasing an…
For an oscar tank, log the core chemistry every time you test: ammonia, nitrite, nitrate, pH and temperature, plus the date of the test and any water change you made alongside it. Ammonia and nitrite should read zero in a cycled tank, and nitrate is the number you manage with water changes, because oscars are heavy…
Record the job as a before-and-after snapshot: test results taken before you started, how much water you changed and whether the replacement matched the tank's temperature, what you rinsed, trimmed or siphoned, and how the fish behaved an hour later. Note anything that looked off — media falling apart, a sluggish…
Note each loss the same way every time: where the batch came from, how the fish were acclimated, what they ate and refused, the signs you saw and the order they appeared, water test results on the day, and what happened to the batch mates afterwards. Add the quarantine tank's setup and anything shared between batches…
Log the pair as a relationship, not just as two fish: who eats first and who hangs back, where each one rests, how often they lip-lock, clean a surface together or chase, and how long chases last before things settle. Add daily water test results, feeding amounts, fin condition and any marks, plus what changed in the…
Your emergency notes should let a stranger keep the tank alive for a day without you: a stock list with a headcount, which plug runs the heater, filter and lights, your phone number plus a backup person and a local fish shop, and step-by-step cards for a power cut, a failed heater and a leak. Add where the buckets,…
A good handover note describes your betta's ordinary day so precisely that a sitter can spot the unusual: how he greets the front glass at feeding time, the exact amount he eats and how fast, his usual swimming level and resting spots, his normal colour and fin posture, and his typical sleep pattern. Add his tank's…
Keep five things in one place, and you have a record that answers every aquarium question you will ask it. Start with a setup page — tank, filter, heater, lights, substrate and how a water change is done in your house — then the heart of the log: water test readings alongside each change, in one list, so drift can be…
A good shop is not gatekeeping when it hesitates over sensitive cichlids; it is checking whether your water is stable, and a written record answers better than confidence does. The evidence that matters is a run of test results over time — pH and temperature in a narrow band, ammonia and nitrite at zero, nitrate…
Build the file around identification, because a claim fails when the pond fish cannot be proved to be the paper fish: keep a clear top-down photograph of every koi, with its variety name and a written description of its pattern, updated as it grows. Add each fish's source, dealer or breeder, the receipt or certificate…
Log each event while it happens, because memory edits outages afterwards: when the power went and returned, and above all the lowest temperature each tank reached and how fast it fell. Note what you did in order — lids closed, tanks wrapped, battery pump started, feeding stopped — and what each action seemed to…
Write the instructions for a willing beginner, not a fellow fishkeeper: foods named by their container and shelf, and the one idea that matters — too little food is a shrug, too much is a slow disaster. Then remove judgement entirely by portioning every feed into small labelled pots before you go, one pot per feed, so…
Photograph it before release, while the fish is still in its transport bag, close to the glass and unable to hide: both sides, one shot from above, and close-ups of any distinguishing marks, because those quirks identify this fish later. Add what the camera cannot hold — the seller's name for the species and variety,…
Give each clutch its own entry the day it appears: an honest egg count with a photograph, where it was laid, and which female most likely laid it, marked as a guess when it is one. Record the conditions behind it — water temperature, the air gap above the waterline the female needed, recent changes and the…
A baseline is three or four plain lines per tank describing normal on a good day, written so a later change has something to be measured against. Cover feeding response first — who reaches food first, who waits for it to sink, which shy fish is always last — because appetite shifts are the earliest warning most tanks…
Give every drop its own entry on the day you find the fry: the mother, the tank she dropped in, an honest count including any stillborn, and the entry's reference written on the grow-out tank's label so fish and paperwork never separate. Describe colour with a fixed personal shorthand — body colour, pattern, tail…
Start before you touch anything: photograph the failed tank as it stood and write the timeline of symptoms in the order they appeared, because that evidence goes down the drain with the first bucket. List every inhabitant and what happened to each, plus anything added in the weeks before — a plant, a rock, second-hand…
Write the card as decisions a worried non-fishkeeper can act on in under a minute, not as a description of your system. The first lines give the temperature the thermometer should show, the exact heater setting that holds it, and what a healthy filter sounds and looks like, because those two readings settle most…
Build the page around the minute your sitter spends at the tank, not around the equipment cupboard: feeding first — which tank, which food, exactly how much, and where it goes in — then the lights, a top-up line, the thermometer number to check, and one emergency contact. Before you leave, portion each day's food into…
Keep a session log for the planted tank with one entry per working session: which plants you trimmed and roughly how hard, what fertiliser you added written down the same way every time — the product and the measure you actually used, such as pumps or capfuls — and any CO2 change, whether that is the bubble rate, a…
