What Do I Need to Start Fishkeeping (2026): One Kit, Four Parts, About $120

If you are asking what you need to start fishkeeping, buy one 10-gallon freshwater kit and learn the water routine before you buy fish. The Aqueon starter kit was $119.99 when checked and puts the tank, internal filter, LED hood, and preset heater in one box. Add $72.74 in gravel, conditioner, food, a net, and a liquid test kit. That makes a workable first setup $192.73, or about $193 before fish, not the $500 cart that shows up in a lot of aquarium videos.

Stocking, temperature, and water targets depend on the species, so confirm those details with a reputable care guide or aquatic veterinarian.

A 10-gallon tank is a good beginner size because it gives the water some room to absorb small mistakes. A filled tank weighs close to 100 pounds, so use an aquarium stand or a piece of furniture rated for that load. Do not put it on a flimsy shelf just because the empty glass tank felt light in the store.

The four parts in one purchase

1. The 10-gallon glass tank: Aqueon 10-Gallon Starter Kit This is the part that sets the scale for the whole hobby. Ten gallons gives a beginner more stable water than a tiny bowl without taking over a room. Put it on a level, load-rated surface away from direct sun. Check the kit's electrical instructions and local GFCI requirements before filling it.
2. The internal filter: Aqueon 10-Gallon Starter Kit The filter circulates the water and gives beneficial bacteria a home. Those bacteria process ammonia from fish waste, so the filter is not an optional decoration. Follow the maker's care instructions; many fishkeepers rinse reusable media in removed tank water rather than chlorinated tap water to preserve the bacterial colony.
3. The LED hood: Aqueon 10-Gallon Starter Kit The low-profile hood keeps fish from jumping and gives you a simple light for viewing the tank. About eight hours a day is a common starting point, then adjust for the species, plants, and algae growth.
4. The preset heater: Aqueon 10-Gallon Starter Kit The heater handles the temperature for many tropical freshwater fish, but confirm the target range for your species and check the water with a separate thermometer before stocking.

The four numbered parts above are one $119.99 purchase. They are not four separate $119.99 items.

The cheap pieces beyond the kit

You still need gravel, water conditioner, fish food, a small net, and a liquid test kit. A sensible local-store budget is $11 + $8.75 + $6 + $5 = $30.75 for the first four. Use any aquarium-safe gravel you like. The cheap answer is fine here, but rinse it until the water runs clear and never use soap. Water conditioner matters because tap chlorine and chloramine can damage fish and the bacteria you are trying to grow. One common option is Seachem Prime 250 ml Freshwater and Saltwater Conditioner: its label says a 250 mL bottle neutralizes chlorine, chloramine, and ammonia in roughly 1,000 gallons of treated water, far more than a 10-gallon tank will use in its first year. The liquid test kit is the one purchase worth upgrading to a named brand. The API Freshwater Master Test Kit, 800-Test Freshwater Aquarium Water Kit is about $41.99 and tests pH, high-range pH, ammonia, nitrite, and nitrate. It includes four glass tubes, a holding rack, and reagents for about 800 tests. A strip kit may cost less, but many omit ammonia; compare the tested parameters before buying.

Cycle the tank before stocking it

A common fishless-cycle approach is to add the gravel, fill the tank with treated water, start the filter and heater, and add an ammonia source. Follow a reputable care guide for dosing and test ammonia and nitrite every few days. The cycle often takes two to six weeks, but use the target readings for your species rather than the calendar. Bottled bacteria may shorten the wait; it does not replace testing.

When the readings and species guidance say the tank is ready, add a small first group of fish. Feed lightly and remove uneaten food. Many small freshwater setups start around a 20% weekly water change, but adjust that routine using test results and species-specific guidance. Stable water matters more than fancy wood, a CO2 system, or a cabinet full of additives.

What to skip

• A 1-gallon betta bowl. The small volume swings quickly and leaves little room for reliable filtration.
• Saltwater or reef equipment for a first tank. It is a different hobby with a longer learning curve.
• Fish on setup day. The tank needs a working nitrogen cycle first.
• A "self-cleaning" plastic bowl. Fish waste still needs filtration and water changes.
• A giant aquascaping kit, automatic feeder, or expensive centerpiece fish. Buy those after you have kept the water stable for a month.

The total

The real first setup is $119.99 for the four-part kit + $11 gravel + $8.75 conditioner + $6 food + $5 net + $41.99 API test kit = $192.73, or about $193 before fish. If you already have a clean bucket and a small container for water changes, the cheap path stays close to that number. The free part is the patience: cycle the tank, test the water, then stock it slowly.
