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.

Yes, as a condition log rather than a weighing routine: catching an Apistogramma to weigh it causes stress and risks fin damage, so track body shape, colour, appetite, fin condition, and breeding behaviour in writing, backed by photos taken from the same angle. Add water test results to every entry, since these dwarf…
Yes, but reshape it: weighing individual amano shrimp is impractical and stressful, so log health instead through moults, a head count at feeding, colour and activity, and the water test results that govern moulting. Note empty moult shells, any shrimp carrying eggs, and failed moults or unusual stillness, alongside…
Guppies are not routinely vaccinated, so organise records by tank and breeding group rather than by individual fish: strain and sex mix, births and growing fry, water test results, new arrivals and quarantine, and any sickness signs seen across the group. One log per tank, updated at water changes, keeps a…
Pet goldfish have no routine vaccination schedule, so their records should follow growth and water over a long life: variety, size over time, tank or pond and filtration details, water test results, appetite, swimming, and any vet visits. Keep one log per fish if individuals can be told apart, and update it at each…
Corydoras catfish are not routinely vaccinated, so organise their records as a group health log: how many fish are in the shoal, water test results, substrate type, sinking foods offered, and notes on barbels, activity, and any losses or new arrivals. Because individual corydoras look alike, track the shoal as a unit…
Bettas are not given routine vaccinations, so their records are a health history rather than a vaccine card: where your betta came from, water test results, water changes, foods, appetite and fin condition notes, and any illness signs or aquatic vet visits. Keep one running log in entry order, with clear photos of the…
For threadfin rainbowfish, log temperature, pH, ammonia, nitrite, and nitrate, and watch pH and hardness for the soft, slightly acidic water these delicate fish display best in. Keep warmth steady in the mid seventies to low eighties Fahrenheit and treat any ammonia or nitrite as serious, since threadfins are…
For peppered corydoras, log temperature, pH, ammonia, nitrite, and nitrate at every test, and use the temperature column to prove the tank stays on the cool side this hardy species prefers, often comfortable from the mid sixties into the mid seventies Fahrenheit. They accept a broad pH range, so the log's value is…
For panda corydoras, log temperature, pH, ammonia, nitrite, and nitrate, and treat any ammonia reading as urgent, because these small bottom-dwellers live where waste settles and their barbels suffer in dirty substrate. They prefer cooler, soft water, roughly the upper sixties to mid seventies Fahrenheit and slightly…
For kribensis, log temperature, pH, ammonia, nitrite, and nitrate every test, and check hardness regularly, since this West African dwarf cichlid prefers water slightly acidic to neutral rather than the harder alkaline water many cichlids want. Note cave use and spawning beside the readings, because a breeding pair…
For honey gouramis, log temperature, pH, ammonia, nitrite, and nitrate, with hardness checked often enough to confirm the water stays soft to moderate and steady. Honey gouramis suit warm water in the upper seventies to low eighties Fahrenheit and pH from slightly acidic to neutral, and as shy fish they suffer more…
For hillstream loaches, log temperature, pH, ammonia, nitrite, and nitrate, note the strength of flow and aeration beside each result, and pay unusual attention to temperature staying cool rather than tropical. These river fish are generally kept from the upper sixties to the mid seventies Fahrenheit, and a warm spell…
For ghost shrimp, log temperature, pH, ammonia, nitrite, and nitrate, and track general and carbonate hardness carefully, because shrimp moult and need stable minerals to form a new shell. Ammonia and nitrite matter even more here than in many fish tanks, since shrimp are small invertebrates with little tolerance for…
For Endler's livebearers, log temperature, pH, ammonia, nitrite, and nitrate, and give general hardness real attention, because these small livebearers do best in harder, mildly alkaline water rather than soft water. Note fry appearances beside the readings, since a colony that keeps producing young adds waste load…
For discus, log temperature, pH, ammonia, nitrite, and nitrate at every test, with general and carbonate hardness close behind, because these warm-water fish react to small shifts that hardier species shrug off. Discus are usually kept hot, in the low to mid eighties Fahrenheit, and in soft, slightly acidic water, so…
For convict cichlids, log temperature, pH, ammonia, nitrite, and nitrate every time you test, plus general hardness and carbonate hardness often enough to catch drift in this hardy but messy fish's water. Note each reading beside what the pair was doing at the time, because a breeding convict pair eats more, digs…
For clown plecos, log temperature, pH, ammonia, nitrite, and nitrate, and watch nitrate most closely of all, because a wood-eating pleco produces heavy waste in a small territory and levels climb quietly between water changes. Pair each test with two home notes: whether the driftwood is being rasped and shrinking, and…
For chili rasboras, log temperature, pH, carbonate and general hardness, ammonia, nitrite, and nitrate, and keep the log focused on stability above all, because these tiny blackwater fish live in very soft, acidic water and react to swings that larger fish would never notice. Small tanks drift fast, so test in small,…
For bronze corydoras, log temperature, pH, ammonia, nitrite, and nitrate, and treat the nitrogen readings as the priority, because these bottom dwellers live exactly where waste settles and their sensitive barbels suffer first when the substrate zone turns foul. Add a brief barbel and behaviour note with each test:…
For Boeseman's rainbowfish, log temperature, pH, general and carbonate hardness, ammonia, nitrite, and nitrate, and give hardness and alkalinity real attention, because this species comes from hard, alkaline lake water and loses its famous colour in soft, acidic conditions. Add a note on how the males look at morning…
Log temperature, pH, ammonia, nitrite, and nitrate for blue gouramis, and make temperature a headline figure, because these warm-water fish sulk and lose colour in a tank that quietly runs cool. Add a line about behaviour at the surface: normal trips up to breathe are expected from a labyrinth fish, but constant…
For bamboo shrimp, log temperature, pH, ammonia, nitrite, and nitrate, plus general and carbonate hardness, and pair every test with a note about feeding behaviour: whether each shrimp is fanning the current or picking at the substrate. A bamboo shrimp sweeping the gravel with its fans is usually hungry, because a…
Log temperature, pH, carbonate and general hardness, ammonia, nitrite, and nitrate for apistogrammas, with pH and softness at the top of the page, because these dwarf cichlids live in soft, acidic water and breeding behaviour often follows small shifts in it. Add a short note on which fish coloured up, held territory,…
For amano shrimp, log temperature, pH, ammonia, nitrite, and nitrate on a regular rhythm, and add general and carbonate hardness, because successful moulting depends on the minerals those two readings describe. Note each moult you find, any shrimp carrying eggs, and what you changed about feeding or water on the same…
