🐠 Fish Care Guide

Never drop a new fish straight into the water — the sudden change in temperature and water chemistry can shock it. Instead, acclimatise it:

• Float the sealed bag in your tank for 15–20 minutes so the temperature matches.
• Open the bag and add a little of your tank water into it every 5 minutes, for about 20–30 minutes, so the fish adjusts to your water gradually.
• Gently net the fish out and release it into the tank. Avoid pouring the shop/transport water into your tank.

Ideally yes. Keeping new arrivals in a separate small tank for 1–2 weeks lets you spot any disease before it spreads to your main tank. If you don't have a quarantine tank, at least watch new fish closely for the first week and avoid mixing many sources at once.

A rough guide is about 1 guppy per 2 litres of water, but more space is always better. Guppies are social and do well in groups. Keeping more females than males (e.g. 2–3 females per male) reduces stress on the females from constant chasing.

Feed small amounts once or twice a day — only as much as they can finish in about 1–2 minutes. Overfeeding is the most common beginner mistake: leftover food rots and fouls the water. A guppy's stomach is tiny (about the size of its eye), so little and often is best.

A good quality flake or micro-pellet made for tropical fish is the staple. Vary the diet for health and colour:

• Live or frozen foods like brine shrimp, daphnia, or bloodworms (a few times a week).
• Occasional blanched vegetables (a little spinach or cucumber).

Variety keeps them healthy and brings out their colours.

Fry need tiny, frequent meals. Crushed flake powder, baby brine shrimp (newly hatched), or commercial fry food work well. Feed small amounts 3–4 times a day. Good feeding in the first weeks gives the best growth and colour.

Healthy adult guppies can go 2–3 days without food safely. For longer trips, use a slow-release holiday feed block or ask someone to feed pre-measured small portions — never leave a big pile of food, as it will pollute the water.

Guppies are livebearers — the female gives birth to free-swimming fry rather than laying eggs. If you keep males and females together, they will breed readily, often every 3–4 weeks. You can tell a pregnant female by her rounded belly and a darkened "gravid spot" near the tail.

Adult guppies (including the parents) will eat fry. To save them:

• Provide dense plants (real or artificial) where fry can hide.
• Or move the pregnant female to a separate tank / breeding box just before she gives birth, then return her after.

Fry grow quickly with good food and clean water.

Guppy fry typically show colour by 4–6 weeks and reach near-adult size by about 3 months. Females can begin breeding from around 3 months old, so separate by sex early if you want to control breeding or keep strains pure.

Guppies are hardy and adapt well. They prefer water that is slightly warm (around 24–28°C) and neutral to slightly hard. Stable conditions matter more than perfect numbers — avoid sudden swings in temperature or chemistry.

Change about 20–30% of the water once a week. Regular partial water changes are the single most important habit for healthy fish — they remove waste and keep the water fresh. Use a de-chlorinator if your tap water is chlorinated.

A filter keeps the water clean and houses helpful bacteria that break down fish waste. A new tank should be "cycled" — run the filter for a couple of weeks (ideally with a source of ammonia) so these bacteria establish before adding many fish. Adding fish too fast to a brand-new tank is a common cause of losses.

In a warm climate like much of India, indoor tanks often stay in the guppy's comfortable range without a heater. In cooler areas or air-conditioned rooms, a small heater helps keep the temperature stable, which guppies appreciate.

Hardy, low-maintenance plants are best to start: Java fern, Anubias, Vallisneria, and Java moss all tolerate a wide range of conditions and don't need special lighting or CO₂. They also give fry great places to hide.

Yes — live plants absorb some waste, provide shelter and shade, and help keep the water healthy. They also make the tank look natural and beautiful. Even a few easy plants make a noticeable difference.

Most easy plants just need reasonable light (a basic aquarium light for a few hours a day) and the nutrients already in the tank from fish waste. Trim dead or yellowing leaves, and don't bury the crown/rhizome of plants like Anubias and Java fern — tie them to wood or rock instead.

Cloudy water in a new tank is usually a harmless bacterial bloom that clears on its own in a few days. In an established tank it often means overfeeding or too much waste. Reduce feeding, do a partial water change, and make sure your filter is working.

White spots like grains of salt suggest "ich" (a common parasite), often triggered by stress or temperature swings. Clamped fins and listlessness signal stress or poor water. First steps: test and improve water quality, keep temperature stable, and treat with a suitable aquarium remedy following the instructions. Isolating affected fish helps. This is general guidance — for persistent illness, consult an experienced aquarist.

Gasping at the surface usually means low oxygen or poor water quality. Do a partial water change, make sure there's surface movement/aeration, and check you're not overstocked or overfeeding. If it's sudden and severe, a larger water change is the safest immediate step.

The basics cover most of it: don't overfeed, do weekly partial water changes, don't overcrowd, keep conditions stable, and watch your fish daily so you notice changes early. Healthy water means healthy fish.
