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.

Keep one book, but never one merged record: give each tank its own clearly divided section with an identical layout, so the system is shared while the data never mixes. Start each section with a header page covering that tank's stock, equipment, feeding schedule, and its normal test ranges, then add dated one-line…
Keep one diary per tank and write an entry every time a heater or filter behaves oddly, even when the fault clears on its own. Record the same details for the entries the diary covers, note the date each time, and review the diary monthly for repeats such as a heater that drifts each cold spell or a filter that…
Track the trend instead of chasing an exact census. Once a month, on the same day, make one log entry with five fields: the date, the full number of shrimp you can count in one photograph of the feeding area, the size groups present, the number of berried females you can see, and the number of fresh empty molts you…
Keep one folder for each tank, and inside it one equipment entry for each filter, heater, light and pump. Give every entry the same six pieces: the receipt, the guarantee card, the purchase date, the date the item went into service, the model and the serial number. Photograph or scan paper copies during the week of…
Log every snail or shrimp delivery on the day it arrives, using one line per batch with six fields: the date, the species, the number added, the shop, the destination tank and an observation covering the following 14 days. Write deaths inside that observation field rather than leaving a silent gap, and record odd…
Give each goldfish a separate page that starts with four header details: its name, a clear photograph, its arrival date and its variety. Under that header, add one dated entry whenever something changes, and give each entry the same seven parts: the date, appetite, body marks, behaviour, a size estimate, any water…
Build the chart as a grid a tired relative can read at a glance: one row for each day, one column for each tank, and inside each cell the food name, the amount in plain measures such as one pinch or half a cube, the feeding time and a tick box. Add a bold footer rule that covers every cell on the chart: if a box…
Record temperature, pH, ammonia, nitrite and nitrate for every tank, plus KH and GH so you can see whether your pH is stable or drifting, and salinity as well if the tank is marine or brackish. Note the date, the result and any water change or new arrival alongside each test, because a single reading means far less…
Log seven things in a grid, one row per check: the date, temperature, ammonia, nitrite, nitrate, the percentage of water changed, and a behaviour and appetite note — with tick boxes for the heater and filter checks. Write the ranges at the head of each column (temperature 76–82 °F, ammonia and nitrite at zero, nitrate…
Put a dry-erase board beside the tank and agree one line per change, with four fields: the date, the percentage of water changed, the initials of the carer, and a tick once the dechlorinator was added. Whoever finishes the change writes the line before leaving the room, so the board shows the last change, who did it,…
Leave a short written sheet that removes every guess, because overfeeding by a kind helper is the classic holiday disaster. State the food, the exact amount per tank, and the feeding times, and pre-portion each day's food into labelled pots so the feeder never judges a pinch. Add the light timer setting, a daily check…
A useful angelfish stocking record tracks each fish as an individual, not just the tank as a whole. For every fish, write its variety and colour form, how many were bought together, the date it was acquired, where it came from, the price paid, its size on arrival, and the dates it spent in quarantine before joining…
Yes, keep a log, because memory is a poor record of slow changes and a written trend turns a puzzling fish problem into a solvable one. Record the date, the time, ammonia, nitrite, nitrate, pH, and temperature, plus any action you took such as a water change or a filter clean. Test weekly once a tank is settled, and…
Keep a separate log line for each of the three media types in the filter (the sponge, the bio-media, and the carbon), and record every touch in six fields: date, media type, action taken, water used, flow afterwards, and next due note. Follow one rule: only one media type is rinsed or replaced in any session, and…
Build the log around one line per test, with columns for the date, temperature, pH, ammonia, nitrite and nitrate, plus the size of any water change and a feeding note. Test on the same day each week, before the water change, and plot the nitrate readings on a simple line graph: a baseline that rises week after week,…
Keep one log for the tank with a line for every task. For each water change record the date, the volume changed, whether conditioner was added, and the temperature of the replacement water. For filter work record the date, which media you rinsed or replaced, and a simple flow note — normal, reduced or restored after…
Use one line per feeding with five fields: the date, the food offered, the amount offered, how much was eaten or left, and a short note on behaviour and leftovers. Plan the rotation on a weekly grid first — for example sinking pellets, a sinking wafer, thawed frozen food and a vegetable-based food on different days —…
Give every tank its own simple log and label everything with the tank name, from test kits to food. For each tank, note its livestock, water test dates, treatments used, and equipment changes in the same place every time, rather than relying on memory. A quick weekly update takes minutes and saves real confusion when…
Keep a living list of every fish, invertebrate, and plant, with when each was added and any notes on temperament or losses, and update it whenever something changes. That list helps you avoid overstocking, plan compatible additions, and spot patterns if a problem follows a new arrival. If you ever rehome a fish,…
Yes, noting the brand, model, and purchase date for heaters, filters, lights, and test kits makes replacements and troubleshooting far easier, especially when something fails suddenly. It also helps you track things like bulb age and filter media changes that are easy to forget. With KinsLe, keeping those equipment…
Build a simple recurring rhythm — daily feeding and visual checks, weekly testing and partial water changes, and monthly filter and equipment checks — and write it down where you'll actually see it. Consistency matters more than doing everything perfectly on one big cleaning day, which can actually stress fish and…
Log the date and the actual readings for temperature, pH, ammonia, nitrite, nitrate, and salinity for saltwater tanks, rather than just writing 'all good.' Over time those notes reveal slow trends you'd never spot from memory and make troubleshooting much faster. KinsLe's Pet Passport is built as your pet's records…
