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.

Feed koi by water temperature: in spring, restart with small, digestible meals that grow as the water warms and their appetite rises, then taper amounts through autumn as the water cools. Stop feeding once the water holds below about 50 °F (10 °C), and leave the fish unfed through properly cold winter water, resting…
Get the landlord's written agreement first, because a large tank is heavy, holds a lot of water, and a pleco will outlive most tenancies — plan now for how the fish and tank move when you do. Check floor strength for the filled weight, water-damage cover and where the tank sits, and agree what happens if a future move…
Arrange the tank before the baby arrives: simplify the setup, put the lights on timers, and settle into one thorough maintenance session each week that covers the water change, glass, filter check and gravel clean in a single sitting. Postpone new stock and rescaping until the household finds its feet again, because a…
Child safety is settled before any koi arrives, by one of two real routes: a rigid grille or mesh held just under the surface, strong enough to bear a child's weight, or a fence around the pond with a self-closing, latched gate. A loose net alone does not protect a child and should never be the safety plan. Any pond…
A snail-friendly planted tank works as a living-room centerpiece when contrast does the showing: dark substrate and a dark background make pale and patterned shells stand out, broad-leaf plants give the snails shaded grazing and resting surfaces, and gentle lighting keeps the whole display calm to sit beside. Leave a…
Plan the household calendar around the tank: during sprays and paint fumes, the tank is covered and surface exchange is stopped — air pumps off, covers on — until the air clears. Party guests are briefed before they arrive: no tapping, no feeding, and food and drinks are kept off the tank top, where a spill goes…
Plan a tall angelfish tank for the adults it will hold: tall planting at the back, open swimming water in front, and lighting strong enough to still reach the lower leaves as the plants grow up and shade themselves. Stock for adult territories, not for the small juveniles in the shop tank — plan for the adult fish,…
A koi pond needs filtration in a fixed order — mechanical removal of solids first, then biological capacity — and the whole system oversized for the pond rather than matched to its bare volume. Fit a bottom drain and surface skimming so waste reaches the filter instead of settling in the pond. Size everything for the…
A multi-tank home needs its load added up honestly: calculate the total load of heaters, filters, and lights, spread tanks across circuits, fit drip loops on every cord, and label plugs per tank so nothing is unplugged by mistake. The outage plan runs battery air pumps first for oxygen, insulates tanks to hold heat,…
A breeding guppy setup changes the home it sits in: spare tanks are needed for grow-out and for separating the sexes, because fry left with adults get eaten and sexes left together breed again before the first young have grown. The week changes too, with more frequent feeding, water changes, and sorting built in, and…
Besides algae, plecos graze on vegetables offered weighted or clipped so they sink, algae wafers, and sinking staple foods, and they rasp biofilm and soft driftwood as part of the diet itself. Feed shy species after lights-out, remove uneaten vegetables before they foul the water, and remember that some pleco species…
Baby corydoras eat food small enough for tiny mouths and soft enough to manage: crushed sinking foods and powdered fry food, plus tiny live or frozen foods when available, all offered in small amounts several times a day. The food has to reach the bottom of the tank, because the fry shelter among plants and cover down…
In a 10 to 20 liter tank, start with a group of ten cherry shrimp, and expect a settled colony to grow into dozens through breeding rather than buying the final number on day one. The real limit is food surface and water stability, not a stocking formula, so no per-liter or per-shrimp rule decides when the tank is…
Layer several defenses instead of trusting one trick: remove the shallow wading shelf a heron needs by keeping depth and steep sides at the edge, stretch a taut net or a fishing-line grid over the surface, and give fish underwater hiding cover and planting to vanish into. A heron is a patient wading hunter, so each…
Prepare the whole pond, not just the feeding: taper food gradually as the water cools and the fish slow down, stopping the rich summer pattern rather than cutting it off overnight. Work through a staged pond and filter clean before deep winter, net fallen leaves out before they rot on the bottom, and plan to keep a…
Set the tank against a calm wall, out of direct sun, away from doors that bang and speakers that thump, and where foot traffic passes slowly rather than streaming past the glass all day. Give the school a solid background and planting to retreat behind, so the tetras feel covered instead of exposed on every side, and…
Plan safety into the design itself: edges that are visible and stable underfoot, a fence or barrier that keeps young children from reaching the water alone, or a rigid safety grid sitting just below the surface, plus an exit slope so a dog or child who slips in can climb out. Site the pond away from ball games and the…
Start at the tank in a small apartment: a close-fitting lid or cover glasses cut evaporation sharply, and evaporation is where the extra humidity begins, long before windows stream or paint starts to suffer. Then manage the room through winter with brief daily ventilation even on cold days, a dehumidifier where…
Trace the sound before changing anything: a low hum usually points to vibration through the cabinet, splashing points to the return, and a rattle often points to a worn or gritty impeller. Seat the filter firmly, cushion every contact point with the stand, clean the impeller, keep the water level high enough to quiet…
Keep the shrimp tank tightly covered at all times and treat the air around it as part of the water: never use aerosol sprays near the tank, and apply cleaners to a cloth away from the counter instead of spraying surfaces beside it. If the kitchen itself must be treated, seal the tank top, cover it, and ventilate the…
Make the tank physically hard to harm: a solid, tip-proof stand a toddler cannot rock, a secure lid a small child cannot lift, filter cables tucked out of reach, and fish food stored where little hands cannot pour it in. Then teach one clear rule — no tapping the glass — and give the toddler a supervised job instead,…
Keep a corydoras species tank interesting for years by deepening it rather than remaking it: keep corydoras as one species in a group large enough to act together, on sand substrate with leaf litter, and let that group be the whole bottom community. Make small seasonal changes to light, litter, and layout instead of…
Use a proper aquarium stand that supports the full footprint of the tank, sits level, and cannot rock, then place it against a load-bearing wall with the tank running across the floor joists rather than mid-span. Plan on roughly ten pounds per gallon once the tank is filled — a planning estimate that counts the water…
Cherry shrimp breed readily in a mature planted tank with moss and biofilm, sponge filtration, no fish, and a starting group of 10 or more mixed shrimp. Berried females carry eggs under the tail until tiny babies hatch and shelter in moss, grazing the same biofilm the adults eat. Stable water is the keeper's whole…
