A healthy aquarium is a balanced one — water chemistry, filtration, stocking and feeding all work together, and most fish problems start with the water.

In its first six months a young angelfish should grow from a small, round-bodied juvenile into a tall, triangular fish with lengthening fins, steady deepening of the body, and bolder behaviour at feeding time. Watch for even growth on both sides, fins that extend without tearing or clamping, and a youngster that holds…
A young white cloud mountain minnow in its first two months does best on two or three very small meals a day, each eaten within a couple of minutes, because its stomach is tiny and growth is fast. Rotate finely crushed flake, tiny micro-pellets, and small frozen or live foods so no single food dominates, and siphon…
Feed a young guppy four to five tiny meals a day during its early weeks, using finely crushed flake or powdered fry food it can swallow, then taper to three meals as it juveniles and two a day approaching adult size. A healthy adult guppy needs only one to two small meals daily, and every stage should be portioned to…
For its first two months at home, feed a young goldfish three to four small meals a day, only what it finishes in about two minutes, using soaked sinking pellets sized for its mouth. As the goldfish grows, reduce to two meals a day, then one to two for an adult, keeping variety with occasional vegetables while…
In its first two months, a young corydoras catfish should get two to three small sinking meals a day, placed where the group rests so the food actually reaches the bottom. As it grows, settle to one main evening meal a day, with the group fed after the mid-water fish so pellets are not stolen before they sink.…
During its first two months, a young cherry shrimp mostly grazes biofilm all day, so offer only a tiny supplemental feeding every other day, small enough to vanish within a couple of hours. As the shrimp grows and the colony settles, shift to modest feedings a few times a week, letting algae, leaf litter, and plant…
During its first two months at home, a young angelfish should be fed three to four small meals a day, each eaten within a couple of minutes, mixing fine crumbled food with small live or frozen options as it grows. As the angelfish matures, drop to two meals a day, then one to two for an adult, watching that its belly…
A young white cloud mountain minnow needs a little more rest than an adult, around ten to eleven hours of quiet darkness versus about eight to ten for a healthy adult shoal. Youngsters rest together low in the tank with fins folded close, and because this species likes cool water, keep their night free of warm room…
A young guppy needs more rest than an adult, about ten to twelve hours of darkness each day against eight to ten for a healthy adult. Fry and juveniles drop into floating plants or rest low and still during the dark period, and they startle easily, so keep the light on a timer and the tank top covered. In KinsLe, Care…
A young corydoras catfish needs more total rest than an adult, roughly ten to twelve hours of quiet spread across the day in sheltered naps, while adults rest less and roam more at dusk and after dark. Youngsters doze together on the substrate in a group pile, so give them smooth sand and a cave or broad leaf to nap…
Young cherry shrimp do not sleep in the usual sense; they pause, graze, and hide in short still spells, and shrimplets need a longer lights-off period than adults, around ten to twelve calm hours versus eight to ten for adults. The young ones rest tucked in moss or under leaves where they also moult, so keep light…
A young celestial pearl danio needs a longer unbroken dark stretch than an adult, around ten to twelve quiet hours against about eight to ten for a settled adult shoal. These tiny fish rest low among plants rather than closing their eyes, and youngsters spook easily, so fade the light gradually and keep the tank away…
A young angelfish does not sleep with closed eyes, but it needs a longer, steadier dark period than an adult, ideally around ten to twelve hours of dim, undisturbed rest while a healthy adult settles well on roughly eight to ten. Keep the young fish's lights on a predictable timer and give it tall plants to hover…
Tell a young betta's sex by combining signs rather than trusting one: young males develop longer, flowing fins, richer colour and a larger flap under the gill that shows when they flare, while young females stay shorter-finned and develop a tiny white egg spot on the underside between the belly and tail fins. Very…
A young white cloud mountain minnow is growing normally when fry steadily gain length, the pale stripe along the side brightens, and the young fish school together in open water to feed. These are small fish that mature at only a few centimetres, so growth is measured in millimetres and patience matters more than with…
A young guppy is growing normally when fry gain size week by week, young males start showing colour and a pointed anal fin, and young females develop a dark spot near the belly. Guppy fry are born free-swimming and hungry, and with frequent small meals they change noticeably within their first month. A fry that stays…
A young goldfish is growing normally when it gains length steadily month by month, stays deep and well-covered through the body, and feeds boldly at every meal. Single-tailed types stretch out fast and lanky, while fancy types grow rounder rather than longer, so judge your fish against its own variety. Measuring…
A young corydoras is growing normally when its body deepens steadily, its barbels stay long and intact, and it roots through the sand with its group instead of resting alone. Juveniles of the larger corydoras types put on most of their growth in the first months, rounding out from a slim fry shape into the familiar…
A young cherry shrimp is growing normally when it sheds its shell often, gains visible size week by week, and grazes actively while its red colour deepens. Newly hatched cherry shrimp are only a few millimetres long and almost clear, and healthy juveniles leave pale cast-off shells on plants and gravel between feeds.…
A young betta growing normally lengthens steadily, its body thickening behind the head while colour deepens and the fins unroll and extend a little each week. It should patrol its tank, flare at its reflection or your finger, and attack meals with quick, accurate strikes. Slow growth — best judged against dated…
A young angelfish growing normally gains height as well as length, its body deepening into the familiar disc shape while the fins lengthen and stay unclamped. It should feed boldly alongside its siblings, hold a gently rounded belly between meals, and look visibly larger when you compare week to week rather than day…
Book a young betta's first full health check once it has settled and is feeding reliably, ideally within its first few weeks with you, or straight away if it arrived thin, damaged, or refusing food. Because many bettas are seen by an aquatic or exotic-animal veterinarian rather than a general practice, call ahead to…
In the first week, young guppies usually settle faster than almost any other fish, exploring the whole tank within hours and feeding confidently by the first or second day. Expect males to begin displaying to females almost immediately, with fin-flaring and persistent following that should stay playful rather than…
In the first week, young goldfish are usually the boldest new fish of all: many explore immediately, learn within days exactly where food appears, and begin greeting anyone who approaches the glass. Expect constant gentle foraging through the substrate, rapid visible enthusiasm at mealtimes, and a surprisingly heavy…
