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.

Give the tank stability in layers: the water itself is your first buffer, so a larger volume swings more slowly, and a lid plus insulation on the back and sides slows it further. Heat with a reliable thermostat heater — or two smaller heaters sharing the job, so one failure cannot cook or chill the tank — and add an…
Use a solid, opaque divider that fits floor-to-lid with no gaps at the edges, because two male bettas must never reach each other — or even spend their days watching each other. Each side needs its own share of heated, filtered water, its own resting plants near the surface, and at least a five-gallon share of the…
Treat the hatch like a medicine cabinet: the goal is that feeding happens on purpose, never by accident or enthusiasm. Fit a lockable automatic feeder over the hatch, or add a simple latch clip to the lid that small hands cannot work, and keep the food itself in a sealed container in a high cupboard rather than beside…
Celebrate the way the fish would choose: with food, novelty, and attention. Mark the day with a special treat meal it only gets on occasions — thawed bloodworms or daphnia, or a blanched pea feast for a goldfish — plus one change to enjoy, like a new plant, a rearranged corner, or an upgraded hide. Take the annual…
In outline: water leaves the display through an overflow, drains to a sump tank below, passes through filter media and equipment sections in order, crosses a refugium section if you include one, and a return pump sends it back. The non-negotiables are flood maths — the sump must hold everything that drains down when…
Yes — this is one of the best fish-and-shrimp pairings in the hobby. White cloud mountain minnows are small, peaceful, cool-water fish with mouths too tiny to threaten an adult shrimp, and they share the cherry shrimp's liking for cooler, gently flowing water, so neither species is kept at the edge of its comfort for…
Shrimp, honestly, no — tiger barbs are the classic shrimp-tank mistake. They are relentless, curious nippers that hunt as a group, and cherry shrimp are eaten, amanos are harassed and torn at while moulting, and even large shrimp live under constant siege. Snails fare better but not perfectly: mystery snails get their…
Snails yes; shrimp only in the right setup, and never a breeding cherry colony at full strength. Serpae tetras are beautiful but famously nippy — kept in small numbers they redirect that energy at tankmates, and adult shrimp get chased and picked at until they hide permanently or worse. A large group of ten or more,…
Yes — rummy nose tetras are among the safest fish you can keep with shrimp, with tiny mouths, a shy schooling temperament, and almost no interest in adult shrimp or even in grazing near them. Shrimplets still need moss or fine planting to hide in during their first days, as any fish will snap at something that small,…
Snails yes, shrimp only with real caution: rosy barbs grow much larger than most community fish — up to the length of a hand — and they are boisterous, hungry, and always foraging, so a cherry shrimp reads as a snack rather than a tankmate. Large amano shrimp sometimes hold their own in a big, densely planted tank,…
Generally yes for snails and adult shrimp, with the usual barb caveat about babies: odessa barbs are among the most peaceful barbs, busy shoaling fish whose males colour up a deep red, and they rarely bother an adult cherry or amano shrimp. Their curiosity is the limit — a shrimplet out in the open will be tasted, and…
Yes, with one clear exception: leopard danios are peaceful, fast-moving shoaling fish that leave snails completely alone and pay little attention to adult shrimp, but they will hunt baby shrimp out in the open. Add the shrimp first, so they learn the hiding places before the danios arrive, and give the tank dense…
Yes for snails and adult shrimp, gently qualified for babies: lemon tetras are calm, deep-bodied schoolers that ignore snails and leave grown cherry shrimp in peace, but newborn shrimplets in open water will be snapped up. Plant cover and a feeding routine that keeps the school satisfied make losses small, and a…
Snails yes, shrimp mostly no: gold barbs are boisterous, mid-sized fish that investigate everything with their mouths, and shrimplets and small cherry shrimp will be hunted down over time. Large snails are left alone, and the biggest amano shrimp can sometimes share a tank, but an ornamental shrimp colony should live…
Yes, with the usual shrimplet footnote: glowlight tetras are peaceful, small-mouthed schoolers that leave adult shrimp and all snails alone, though babies caught in open water in their first days can be eaten. A moss clump or cholla wood gives the colony a nursery the fish cannot reach into, and a breeding colony will…
Yes — ember tetras sit near the top of most shrimp keepers' safe lists: they are tiny, gentle schoolers whose mouths are so small that even newborn shrimplets usually survive alongside them. Snails of any size are completely ignored, and the embers' warm colour shows best against the green planting a shrimp colony…
Snails yes, shrimp only with real caution: Congo tetras grow to a size where an adult cherry shrimp looks like food, and a hunting school will steadily thin out a colony even if a few survivors hide well. Large nerite and mystery snails are unbothered, and big amano shrimp sometimes hold their own, but small…
Yes, and celestial pearl danios are among the safest fish you can keep over a shrimp colony: they are tiny, shy mid-water fish whose small mouths leave even most shrimplets alone, and they ignore snails entirely. Dense planting still helps, because these danios live close to cover and bolder babies venture further…
Yes — cardinal tetras are one of the classic shrimp-safe community fish, with small mouths and a peaceful temperament that leaves adult cherry shrimp and nerite or mystery snails alone. Baby shrimplets hiding in open water may still be picked off, so give the colony dense moss or fine-leaved plants where newborns can…
A hillstream loach needs a long tank rather than a tall one: around 30 gallons with a footprint near 80 centimetres long gives a small group room to graze and claim their own smooth rocks. The size is really about what the water must do - cool, highly oxygenated and moving fast - which a longer tank with a powerhead…
Yes - black skirt tetras can live safely with snails and with adult shrimp, provided the school is big enough and the shrimp have cover. A group of six or more tetras keeps their nippy energy inside the school, while a lone pair is far more likely to bother tankmates. Adult amano and cherry shrimp are usually left…
Chili rasboras come from soft, acidic peat-swamp water, and they suit a temperature of roughly 73 to 79 degrees Fahrenheit with a pH between about 5.0 and 6.5. They tolerate a wider span for short periods, but steady warmth and gentle acidity are what bring out their colour and confidence in a home tank. Because they…
Bronze corydoras suit almost any peaceful community fish that will not nip, chase or eat them: small tetras, rasboras, guppies and other livebearers, dwarf gouramis, and other corydoras species all mix well, and the bronze cory's own first companions should be more of its own kind, kept as a group. Avoid large or…
Boeseman's rainbowfish suit peaceful, active companions that enjoy the same warm, well-oxygenated water and mid-to-upper swimming space: other rainbowfish of similar size, larger tetras, rasboras, corydoras and peaceful gouramis all work well. Avoid fin-nippers such as tiger barbs, slow long-finned fish that get…
