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.

A pea puffer needs more daily attention than most nano fish: a proper meaty feeding it can hunt, a watch on who is eating and who is being chased, and a check that every puffer's belly is gently rounded by evening. Pea puffers rarely thrive on dry food alone and their ever-growing beaks need snails and other shelled…
A Norman's lampeye needs a short daily routine: small feedings taken at the surface, a check that the lid is secure, and a look at the glowing blue eye ring that gives this little killifish its name. Lampeyes school near the top and jump readily, so cover and surface food matter more than anything elaborate. A dull…
A nerite snail needs almost no direct daily care, just three quick checks: it is upright and moving, the lid is closed against its climbing escapes, and there is still algae in the tank for it to eat. Nerites graze constantly and cannot breed successfully in fresh water, so a too-clean tank, not neglect, is the common…
A licorice gourami needs quiet, precise daily care rather than much of it: a small offering of tiny live or frozen food, a check that the water is still soft, dark, and nearly still, and a patient look for a fish that may hide most of the day. These peat-swamp gouramis fade quickly when water turns harder or brighter…
A least killifish needs a gentle daily routine of small feedings and a careful look through the plants, because this tiny livebearer drops newborn fry often and both adults and babies are easy to overlook. Feed finely crushed food the small females can manage, and check daily whether new fry have appeared in the…
A hillstream loach needs little hands-on feeding most days, but it needs a daily check that its river is still running: strong flow, rippling surface, and cool, oxygen-rich water. These loaches graze algae and biofilm from smooth rocks all day, so daily care is mostly confirming the current never stopped and that…
A fork-tail rainbowfish needs a lively but simple daily routine: one or two small feedings of food sized for a small mouth, a check that the filter flow is running well, and a minute watching the school race and display. These active New Guinea rainbowfish show their best yellow forked tails when the water stays clean…
A clown killifish needs brief daily care centred on the surface it lives at: a check that the tight-fitting lid is fully closed, a small feeding of tiny floating food, and a look at the floating plants it shelters under. These little killifish jump expertly and feed almost entirely at the top, so food that sinks is…
A celestial pearl danio needs a short daily routine built around small feedings and patient observation, because these tiny fish are shy enough to go hungry quietly. Scatter fine food into the plants where they hover, then watch long enough to confirm the smaller fish and females actually ate. A daily glance should…
A cardinal tetra school needs only a few focused minutes each day, but those minutes have to be consistent. Offer one small feeding of fine food the fish finish quickly, glance at the heater reading, and count the school while checking that every blue stripe and red tail still looks bright. Faded colour in a cardinal…
A bumblebee goby needs attentive daily care for such a tiny fish: food delivered to the bottom where it perches, often small meaty items offered near its cave, plus a check that bolder tankmates are not eating everything first. Glance daily at its chosen territory, its colour and roundness, and the tank's temperature…
A boesemani rainbowfish needs modest but consistent daily care: one or two small feeds of varied food, a quick check that the whole school is active with males showing colour, and a glance at temperature, filter flow, and water clarity. These are large, energetic schoolers, so the daily habit that matters most is…
Vacuum a guppy tank with the flow deliberately weakened, by pinching the siphon hose, so small fish and fry are not pulled toward the intake. Clean open gravel in brief passes, hover lightly over planted areas where babies hide, and check the waste bucket carefully before you pour it away. Keep the session short and…
Goldfish root through gravel constantly, so vacuum thoroughly but unhurriedly, letting the fish wander away from the nozzle on their own. Push the siphon deep in each spot, since goldfish waste and uneaten pellets settle well down, and work in halves if the tank is large so one session never strips too much water.…
Corydoras feed on the bottom you are about to clean, so vacuum in calm sections and let the group shuffle ahead of the nozzle rather than scattering them with fast sweeps. Keep the siphon shallow around their favourite resting patches, because their whisker-like barbels are delicate and clean, undamaged gravel…
A betta's long fins and weak swimming make gentle technique essential: use a small siphon, pinch the hose to soften the flow, and vacuum in short passes away from where the betta rests. Keep sessions brief, never corner the fish with the nozzle, and watch that no fin edge is drawn toward the intake. Replace the water…
Work the gravel vacuum slowly on the opposite side of the tank from where the angelfish are holding, and let them retreat rather than chasing debris into their territory. Keep your hand movements low and unhurried, pause if fins clamp or the fish press into a corner, and vacuum only part of the substrate each session…
Zebra danios are hardy and fast, so the main risks are jumping and chasing the siphon. Keep the lid ready to cover gaps, remove about a quarter of the water while siphoning the gravel, and count the fish before and after because a danio can slip into the bucket unnoticed. Refill with conditioned water close to tank…
Kuhli loaches hide in substrate and under wood during the day, so siphon gently and never plunge the vacuum blindly where they may be buried. Remove about a fifth of the water, working in visible areas and checking the bucket before emptying it in case a slender loach was drawn up. Refill with conditioned water…
Harlequin rasboras are a peaceful schooling fish that dislike sudden change, so keep the swap modest, around a fifth of the tank, and match the new water closely in temperature before it goes in. Condition tap water to remove chlorine, siphon debris lightly from the substrate and plant bases, then trickle the refill…
For guppies, remove roughly a fifth to a quarter of the water with a gentle siphon, taking care around plants and any tiny fry hiding near the surface or in floating cover. Treat tap water to remove chlorine, match its temperature by hand, and pour it back in slowly so the current does not toss these small fish…
Goldfish produce heavy waste, so remove about a quarter of the tank water on a regular schedule, siphoning from the gravel where uneaten food and droppings collect. Fill a bucket with tap water, treat it to remove chlorine, and let it sit until it feels the same temperature as the tank before adding it back slowly.…
Change water in a corydoras tank in modest portions, hovering the siphon just above the substrate instead of digging it in, because corys rest on the bottom, startle as a group, and can be drawn toward an unguarded intake. Vacuum waste from the surface of sand or smooth gravel, keep the removed portion moderate since…
Before siphoning a bristlenose pleco's tank, check every cave and the underside of driftwood, because your pleco is probably clamped to one of them and must never be lifted out or sucked against the tube. Siphon out roughly a quarter of the water while vacuuming the generous waste these fish produce, leave some algae…
