Betta Tank Setup Checklist: Everything a New Betta Actually Needs

Bettas are one of the most popular fish for beginners, but they're also one of the most commonly misunderstood. Despite what those tiny cups and vases at some stores suggest, a betta needs a real, thoughtfully set-up tank to thrive. If you're about to bring one home, this checklist walks through everything your betta actually needs — so you can set it all up before the fish arrives.

Tank Size: Bigger Than You Think

Bettas are not "bowl fish." The bowls and cups you often see are holding tanks, not homes. A single betta does best in a proper aquarium with stable, filtered water and room to explore. A larger volume also keeps water parameters far more stable, which means a healthier, more active, and more colorful fish. Skip the bowl and start with a real tank — browse our glass aquariums for the right size.

Heater and Thermometer

This is the step most new betta keepers miss. Bettas are tropical fish and need consistently warm water — they become sluggish, stressed, and prone to illness when kept too cool. That matters even more in Cheyenne, where homes can get chilly and temperatures swing between day and night. A reliable aquarium heater plus a thermometer to confirm the temperature are non-negotiable for a happy betta.

Gentle Filtration

Bettas need a filter to keep their water clean and cycled, but they're weak swimmers with long, flowing fins that can be tossed around by strong currents. Choose a filter with gentle, adjustable flow, or baffle the output to soften it. Our aquarium filtration collection includes gentle options well suited to betta tanks.

Live or Silk Plants and Resting Spots

Bettas love to explore, hide, and rest near the surface. Provide plenty of cover with live or silk plants — avoid hard plastic plants that can tear delicate fins. A few broad-leaved plants near the top give your betta a place to rest. Easy live options are a great start; see our beginner aquarium plants.

Substrate, Decor, and a Lid

Add a soft substrate, a couple of smooth hides, and — importantly — a lid. Bettas are jumpers and will leap out of an open tank. A lid also reduces evaporation, which is especially helpful in our dry Wyoming climate.

Water Conditioner and Cycling

Before your betta ever goes in, you'll need a water conditioner to remove chlorine from tap water, and ideally a cycled tank so beneficial bacteria can handle waste. Never add a betta to a brand-new, uncycled tank on day one. Our guide on how to cycle a new aquarium explains exactly how, and you can pick up treatments from our water conditioner collection.

Your Before-You-Buy Checklist

Before bringing your betta home, make sure you have: a properly sized tank, a heater and thermometer, a gentle filter, live or silk plants and resting spots, soft substrate and hides, a secure lid, and water conditioner — all set up and running.
