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.

Treat the pond and the tank as two different holidays. The indoor tank needs its water change done a few days before you leave, its lights on their timer, and a tested feeder or a briefed visitor. The pond needs its pump and skimmer checked, the net secured against herons and falling leaves, and the water topped up so…
For a short weekend, the healthiest choice for most established tanks is often the simplest one, because healthy adult tropical fish in a mature, stable aquarium come to no harm missing two or three days of food and produce less waste while unfed, which keeps the water cleaner. An automatic feeder suits a longer…
Two minutes is plenty when your neighbour follows one fixed order instead of improvising. Walk the tank together before you leave: every fish present and swimming normally, filter running with its usual trickle, heater light on, thermometer in its normal range, water level steady, and nothing wet on the floor or…
Bag fish the way the shops do: stop feeding the day before, catch each fish gently, and seal it in a strong bag one-third full of tank water with two-thirds air, doubled up for safety. Bags go upright in a dark insulated box, cushioned so they cannot roll, with a heat pack in cold weather, and travel in the car cabin,…
A hospital stay calls for the tank's simplest possible mode: ask one or two trusted people to share short checks, set an automatic feeder or pre-portion food into daily pots, put the lights on a timer, and agree that water changes wait unless something looks wrong, with a top-up using conditioned water as the only…
Build the cover around simplicity: one trusted person, a short written routine, and food pre-portioned into labelled pots so overfeeding, the biggest holiday killer, cannot happen. Show them the filter, the lights on their timer, where the water conditioner lives, and what to do if a fish dies or the power trips, and…
Start with temperature: float the sealed bag in the tank until the water inside matches, with the lights low and the room calm. For a short trip home from a shop, adding tank water to the bag a little at a time over half an hour or so eases the chemistry change; for fish that spent a day or more sealed in a shipping…
Yes — fish are shipped safely every day by breeders and shops, and the safeguards are well established: the fish are fasted beforehand, bagged in strong bags with plenty of oxygen, packed in an insulated box with a heat or cool pack matched to the season, and sent by the fastest overnight service early in the week so…
With elderly fish the sitter's real task is comparison: a frail old fish can look the same to a stranger on day one and day ten while declining, so checks must measure each fish against a baseline. Before you leave, note and photograph every fish, how it swims, where it rests and how eagerly it feeds, and have the…
Tell them the why, not just the rule, because a sitter who understands the reason will hold the line when the tank looks murky. Tank water is not dirty water awaiting replacement: it is the chemistry your fish are adjusted to, and a large change with cooler tap water can shock fish and stall the filter's bacteria.…
Do not panic about the fish: healthy adult fish in a filtered tank tolerate a feeding gap of several days far better than a well-meaning stranger's improvised rescue, so a short delay is a logistics problem, not an emergency. Spend your effort extending the human chain — ask your sitter to stretch to extra visits, or…
Feeding is the smallest part of a good visit: the real job is a five-minute inspection that catches problems while they are still cheap to fix. Your sitter should count the fish and watch them move, confirm the filter is running and the thermometer sits at its usual mark, check the water level against the line you…
Resist the welcome-home clean: the kindest first hour is spent watching, not working, because fish that coasted on light feeding for weeks are unsettled more by a sudden deep clean than by one more day of holiday routine. Test the water before touching anything, the readings tell you whether the tank needs a partial…
Ask first about water: will your fish live in the shop's central system or a separate tank, and how its temperature and chemistry compare with your home tank, because a fish boarded perfectly can still be shocked twice, going in and coming home. Ask what happens if a fish falls ill, whether new arrivals are…
Size changes everything: a mature koi can weigh ten times a pond goldfish, burns through a bag's oxygen far faster, and fouls its travelling water so quickly that journey length becomes the governing limit. Koi travel one fish per large, heavy-gauge bag, with generous water topped with pure oxygen, boxed upright and…
The sensible plan assumes the failure happens and makes it survivable rather than guaranteeing it never does. Split the life support so no fault stops everything: pump and UV on one circuit, and a small air pump on a separate socket keeps oxygen moving if the main trip goes. Ease off feeding in the days before you…
Leave the tank exactly where it stands and build the break around it: moving goldfish to someone's home for a few weeks stresses them more than a quiet, well-prepared classroom does. In the final school week, rinse the filter media in removed tank water, then do one large water change a day or two before the break and…
Cichlids burn oxygen like fish twice their size — they are active, thick-bodied and stressed in bags — so several in one vehicle need a deliberate air budget: bag each fish singly, with roughly one part water to two parts airspace, and have a shop fill bags with pure oxygen if the drive is long. Carry a…
Work tank by tank with one rule: believe the thermometer, not the heater dial. Confirm each tank's temperature sits in its usual band and the heater's light cycles on and off rather than sticking either way. Watch each light timer through a switch point, or advance it manually, so you know the cycle the fish will…
Restart smaller than your instincts want: offer a first feed at about half the usual amount — less for fish that have been bagged for a long journey — and watch whether it is eaten cleanly within a few minutes before offering anything more. Across the next two or three feeds, step back up to normal portions, because a…
Give every tank a code before anything is caught — T1, T2, T3 — and let that code follow each fish from bag to box to destination room. Write on each bag, in permanent marker on the bag itself and again on tape, the tank code, the species, the headcount and any warning that matters, like an aggressive male travelling…
Fry cannot be left to the adult rule — several small feeds a day is a real need, not a preference, so travelling with fry in the tank means arranging those feeds, not skipping them. The most reliable option is a sitter with micro-portions pre-measured for every feed, since fry food is easy to overdose. An automatic…
Healthy adult tropical fish in a settled tank can generally manage up to about a week without feeding, and many cope with ten days or so, because their metabolism is slow and they pick at biofilm and algae between meals. That window shrinks sharply for fry, tiny species like chili rasboras, and heavily stocked tanks.…
Use a small lidded pot — a pill organiser with one compartment per day works perfectly — for each tank, and fill every compartment with exactly one feed measured the way you feed it at home. Level the flake or count the pellets rather than eyeballing, because the whole point is that the sitter empties a pot and makes…
