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 about $50 in gravel, conditioner, food, a net, and a liquid test kit. That makes a workable first setup about $170 before fish, not the $500 cart that shows up in a lot of aquarium videos.

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 somewhere level, away from direct sun, and close enough to a wall outlet for the filter and light.
2. The internal filter: Aqueon 10-Gallon Starter Kit The filter circulates the water and gives the beneficial bacteria a home. Those bacteria process ammonia from fish waste, so the filter is not an optional decoration. Leave it running continuously, and replace its cartridge only when it is worn out. Rinse filter media in removed tank water, never under a chlorinated tap.
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. Put the light on a timer for about eight hours a day. Longer is not automatically better. Too much light usually means algae before you have learned the rest of the routine.
4. The preset heater: Aqueon 10-Gallon Starter Kit The heater handles the temperature for tropical freshwater fish, but check the water with a thermometer before stocking. The kit removes a major shopping decision, not the need to watch the tank. If the room is cold or the temperature swings, a separate thermometer is a cheap safety check.

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 + $6 + $5 + $20 = $50. 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 is not optional because tap chlorine and chloramine can damage fish and the bacteria you are trying to grow.

Cycle the tank before stocking it

Add the gravel, fill the tank with treated water, start the filter and heater, and add an ammonia source. Test ammonia and nitrite every few days. The cycle is finished when both read zero after the tank has processed an ammonia dose. Two to six weeks is a normal range. A bottled bacteria product can shorten the wait, but it does not replace the test kit.

When the numbers are ready, add a small first group of fish. Feed lightly, remove uneaten food, and change about 20% of the water each week. Test weekly for the first month. That short routine matters more than fancy wood, a CO2 system, or a cabinet full of water 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 conditioner + $6 food + $5 net + $20 test kit = $169.99, or about $170 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.
