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.

After a zebra danio vet visit, write down the vet's findings on body shape and spine straightness across the group, fin condition, and the water results from your sample. Danios are active enough to hide early problems, so add your home notes on appetite, any fish dropping out of the group's constant movement, and…
After a white cloud mountain minnow vet visit, write down the vet's findings on the group's body condition and fin colour, the water temperature the clinic recorded, and any advice about the cool-water setup these minnows prefer. Note losses or new additions to the school since the last visit, and your home…
After a scarlet badis vet visit, write down the vet's findings on colour, body condition, and fin state for each fish discussed, because males in particular can fade or thin quietly in a busy tank. Note what the vet said about live food supply, since a badis that refuses dry food depends on small live prey, and record…
After a rummy-nose tetra vet visit, write down what the vet said about the school as a whole — nose colour across the group, body condition, and any fish that looked thinner or paler than the rest — plus the water results the clinic recorded. Rummy-noses famously blush or fade with water quality, so note the vet's…
After a pearl gourami vet visit, write down the vet's findings on its long thread-like ventral fins, gill movement, and the pearl patterning along its flanks, plus the results of any water tests the clinic ran. Add what you have noticed at home — appetite at the surface, time spent hiding in plants, and whether a male…
After every vet visit for a kuhli loach, write down what the vet found about its skin, barbels, and body condition, any results from the tank water sample you brought, and exactly what home care was advised. Note how the loach has behaved since — hiding more than usual, coming out to eat after lights-out, or rubbing…
After a harlequin rasbora vet visit, record the concern, the vet's findings on the black wedge marking, body fullness, fins, and breathing, how many of the school showed the same sign, and the follow-up instructions with the school-wide watch point. Rasboras are read as a school, so note what the vet advised for the…
After a guppy vet visit, record which fish went, ideally by colour and sex, the vet's findings on tail, body, and gills, whether the vet treated it as an individual case or a tank case, and the follow-up instructions with the spread sign to watch for. Guppies live in groups where problems travel, so also note what the…
After a goldfish vet visit, record the concern, the vet's findings on buoyancy, gills, body, and fins, the water results discussed, and every instruction including the recheck point in the vet's wording. Goldfish visits often hinge on water volume and feeding, so note any change the vet made to either. At home, log…
After a corydoras catfish vet visit, write down the concern, the vet's findings on barbels, belly, fins, and breathing, what was discussed about substrate and group size, and the follow-up instructions with the sign that should prompt a call. Corydoras read their world through their whiskers and live on the bottom, so…
After a celestial pearl danio vet visit, record the concern, the vet's findings on body fullness, fin condition, and the spotted pattern, how many tankmates show anything similar, and the follow-up instructions with their review sign. These tiny, shy fish are usually assessed as a group, so also write what the vet…
For a bumblebee goby, write down the concern, the vet's findings on body roundness, colour bands, and perching strength, the exact water salinity and temperature figures discussed, and every instruction with its call-back sign. These tiny brackish fish decline quietly and eat reluctantly in strange water, so log daily…
After a bristlenose pleco vet visit, record the concern, the vet's findings on belly, bristles, fins, and body condition, what the vet asked about driftwood, diet, and hiding places, and the follow-up instructions with their review point. Back home, note when the pleco resumed nocturnal feeding and whether it returned…
For a boesemani rainbowfish, record the presenting concern, the vet's findings on colour, body depth, gills, and fins, the school context the vet asked about, and all follow-up instructions with their recheck trigger. Note how the fish rejoined the school and whether its blue and orange colour returned at feeding over…
After a betta vet visit, write down the reason you went, what the vet observed about fins, eyes, gills, and body condition, the water results the vet asked about, and every instruction in the vet's own terms, including when to recheck. Add what your betta ate and how it swam in the first days back home, since recovery…
A white cloud mountain minnow diary should record water temperature above all, since this cool-water school drifts with room conditions, plus water test results, water changed, food taken, and whether the whole group is still schooling tightly. Note any fish losing its red fin colour or feeding away from the group.…
For a guppy, record water results, water changed, food offered, tail and body condition, and a headcount that separates adults from new fry. Guppies breed readily and hide illness in a busy group, so a weekly count and a note on any fish isolating itself catch changes a glance misses. Keep recent months in full and…
A goldfish weekly diary should record water test results, how much water you changed, what and how much you fed, appetite and swimming, and any change in buoyancy, breathing, or waste. Keep the entry short enough that you will actually write it after the water change, and note filter rinsing or gravel cleaning on the…
A weekly corydoras diary should record water results and temperature, how much sinking food reached the bottom and was finished, group behaviour at dusk, barbel and fin condition, and the substrate's state, because these bottom dwellers suffer quietly where faster tank mates hide the evidence. Note any cory resting…
A cherry shrimp weekly diary should record temperature, pH, and hardness readings, the water-change size and how change water was prepared, plus that week's molt shells seen, any berried females, new shrimplets, and a rough colony count. Add deaths with numbers, algae and feeding notes, and any new plant, stone, or…
A useful weekly betta diary records that week's water test results and temperature, the size of the water change, appetite and food type, fin condition, activity, and one dated photo, because a betta's decline is usually a slow fade across those exact lines. Add any new decor, tank mate, or odd behaviour the same week…
Start by recording the group size, the variety — standard, longfin, or a spotted pattern form — the source, and a photo of the blue-silver striping on arrival. Note tank length, temperature, and starting ammonia, nitrite, nitrate, and pH results, then keep dated lines on activity, appetite, and any fish that slows…
Record the shoal size, source, and an arrival photo of your white cloud mountain minnows, noting fin colour and any pale or thin individuals. The defining entry for this species is temperature without a heater, so log room and tank temperatures across the day alongside pH and the usual ammonia, nitrite, and nitrate…
Begin with how many scarlet badis you added and their sexes, because the vivid red fish are males and the plainer ones are usually females, and males stake out territories in even a small tank. Photograph each fish, note the source, log starting water results and temperature, and record which live or frozen foods each…
