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.

A white cloud mountain minnow should come with a receipt or transfer note naming the seller or breeder, the size of the school, and which variety you are getting, since golden and long-finned forms are sold alongside the classic type. Ask for the water temperature they were kept at, because these are cool-water fish,…
A sparkling gourami should come with a receipt or transfer note naming the seller or breeder, the number and sex balance of the group, and the water they were kept in, since these little labyrinth fish favour soft, gentle conditions. Ask for their recent foods and whether the group has spawned, as males build bubble…
A scarlet badis should come with a receipt or transfer note naming the seller, a note of how many fish you took and how the seller sexed them, and a feeding history, because many scarlet badis will only eat live or frozen food. Ask about origin too, as wild-caught and tank-bred fish settle very differently, and record…
A Norman's lampeye should come with a receipt or transfer note naming the seller or breeder, the size of the school you are taking, and the water it has been living in. Ask for its recent foods and any health history too, and note whether the group has spawned, since these small killifish scatter eggs in fine plants…
A fork-tail rainbowfish should come with a receipt or transfer note naming the seller or breeder, a count of the school you are taking, and the male-to-female balance the seller kept them in. Ask for their water history and recent foods too, and whether any eggs or fry have come from the group, since these are…
A bumblebee goby should come with a receipt or transfer note from the seller or breeder, and one record matters above all others: the salinity of the water it was kept in, written as a specific gravity reading. Add its recent foods, since many bumblebee gobies only take frozen or live food, plus any quarantine or…
A boesemani rainbowfish should come with a receipt or transfer note naming the seller or breeder, plus records of the group it came from: how many fish you are taking, the male-to-female balance, and roughly how old they are. Ask also for the water the fish were kept in, their recent foods, and any quarantine or…
An emergency contact plan for a guppy should list, in order, a backup keeper who understands small tropical tanks, someone who can enter your home, and the aquatic shop or vet you use, each with a phone number. Add the details a guppy colony depends on: the heater setting, the filter type, the tiny feeding amount, and…
An emergency contact plan for a goldfish should name, in calling order, a nearby backup keeper, a neighbour who can get into your home, and the aquatic vet or fish shop you use, with a phone number for each. Beside those names, record the tank size, the filter and air pump setup, exactly how much food to give, and…
A betta emergency contact plan needs three layers: your own details and where you will be, a nearby person who can physically reach the tank, and an aquatic vet or experienced fish shop that can advise by phone. Add the tank facts that a stranger would need — heater and filter setup, feeding amount, water change…
Yes, keep a simple health log — and skip the weighing, which a white cloud mountain minnow is much too small and lively to make worthwhile. These cool-water schoolers show condition through body depth, the red on fins and lips, and confident schooling, so record those weekly alongside water temperature, which matters…
A health log is a smart move for a threadfin rainbowfish, but do not weigh them — the males' long fin filaments tear easily, and a school this delicate should be assessed by eye, not by net. Record how many filament fins stay intact, whether the school feeds confidently on foods small enough for their tiny mouths, and…
Keep a health log for a sparkling gourami, but weigh nothing — these thumbnail-sized labyrinth fish are stressed by handling, and their iridescent spotting and croaking displays tell you more than a scale. Record whether males croak and tend a bubble nest, how each fish's sparkle looks under tank light, appetite on…
A health log is one of the best habits a scarlet badis keeper can build, and weighing never enters into it — this tiny predator is easily stressed and often reluctant to feed, so appetite records matter more than numbers. Log what live or frozen foods each fish actually ate, whether males hold their red colour, and…
Yes, a simple log suits rice fish well, though weighing adds nothing — medaka are small, hardy schoolers whose condition shows in body depth, spawning activity, and how they handle the seasons. Record when females carry egg clusters, how the group feeds, any thinning fish, and temperature swings if your rice fish live…
Keep the health log and drop the weighing: a Norman's lampeye is a small, quick killifish whose bright blue eye ring is a better health gauge than any scale could give you. Note whether that eye ring stays vivid in every fish, how tightly the school holds together, feeding response at the surface, and any fish…
For a nerite snail, a health log makes sense and a weight log does not — you cannot meaningfully weigh a snail that carries its shell and clings to glass, and prising it off surfaces for a reading risks damaging its foot. Track shell growth and condition, how actively it grazes, whether the foot grips firmly, and the…
A health log is especially valuable for a licorice gourami, while weighing is out of the question — these shy blackwater fish stress easily and hide for much of the day, so what you write down may be most of what you know. Record which cave or leaf each fish uses, whether males show their blue-edged breeding colour,…
Keep a health log, yes, but weighing a least killifish is not realistic — adults are among the smallest livebearers, and netting them for a scale reading risks more harm than the figure prevents. Track instead the females' body depth, the steady trickle of fry, feeding response on tiny foods, and any fish shrinking…
A health log is worthwhile for a fork-tail rainbowfish, but weigh nothing — these slim, fast schoolers are injured and stressed by repeated netting, so condition is judged visually. Record how the school feeds, whether the forked tails and yellow-edged fins stay intact, and whether males are displaying, since a fish…
Yes to a health log, but skip literal weighing — an Endler's livebearer is far too small and quick to weigh without stressful netting, so track body condition by eye instead. Note each male's colour intensity, each female's belly shape, who eats eagerly at feeding, and how many fry appear, because a breeding colony…
Yes, discus reward a careful log more than most fish, but base it on appetite, posture, colour, and breathing recorded at each water change, with growth judged from photos, rather than on weighing fish that stress badly when netted. Pair every entry with temperature and full water test results, because discus…
Yes, but make it a feeding and water log rather than a weight log: a bumblebee goby is far too small to weigh usefully, and its health shows in whether it eats, how round its belly looks, and whether it holds its perch and territory. Log accepted foods at each feeding, the salinity reading of its brackish water, and a…
Yes, in visual form: netting boesemani rainbowfish for weighing stresses a fast, easily startled school, so log colour intensity, body depth, growth estimated from photos, appetite, and any jumping or flashing instead. Record the group as a school, noting males separately when their blue and orange halves fade or…
