Your New Betta
A Take-Home Care Guide
Congrats on the new betta. Whether this is your first fish or your tenth, the next few days set the tone for everything that comes after.
The betta wall at the shop. Pick yours, take it home, then keep reading.
This guide is the short version of what we'd tell you if we had another twenty minutes at the counter. Practical stuff, no fluff, and honest about the parts most stores skip. Keep it handy for the first week. After that, most of it becomes second nature.
Day 1: The First Few Hours
The ride home is stressful for a fish. Keep the bag upright, out of direct sun, and don't shake it. When you get home, follow these steps in order:
- Float the bag in the tank for 15 to 20 minutes to match the water temperature.
- Skip the "dump the bag in" trick. Net the betta out and release just the fish into the tank. The bag water has ammonia in it, and you don't want that going in.
- Lights off for the first night. Let your betta settle in the dark. Don't feed yet.
- Watch, don't poke. If they hide, sulk, or clamp their fins for the first 24 hours, that's normal. They just moved house.
Tank Requirements
This is where most betta problems start. The cup at the big-box store isn't a home. It's shipping packaging. Here's the real minimum:
- 5 gallons, minimum. Bigger is easier, not harder. More water means more stable water.
- A heater. Bettas are tropical. Aim for 78 to 80°F, year-round. Room temperature is too cold in most houses.
- A filter with adjustable or gentle flow. Bettas don't love being blasted around.
- A lid. Bettas jump. We've seen it. Cover any gaps around cords too.
- Live or silk plants. Plastic plants tear fins. If you can't pull pantyhose across it without snagging, it isn't safe.
Tank shape matters less than tank volume. A wide, shallow 5-gallon beats a tall, narrow one. Bettas breathe air at the surface and prefer easy access to it.
Water Care
Keeping the water right is 90% of fishkeeping. The other 10% is feeding. That's the whole job. Here's what to test for, and how often:
Ammonia and nitrite are the two that can kill a fish overnight. Watch those first.
| Parameter | Target | How Often |
|---|---|---|
| Ammonia | 0 ppm | 2× per week (first month) |
| Nitrite | 0 ppm | 2× per week (first month) |
| Nitrate | Under 20 ppm | Weekly once cycled |
| pH | Stable (6.5 to 7.5) | Weekly |
| Temperature | 78 to 80°F | Daily glance |
| GH | 4 to 8 dGH | Monthly |
| KH | 3 to 6 dKH | Monthly |
For testing, we use a two-tool setup. The Fritz 6-in-1 Test Strips are perfect for quick daily or weekly checks (six parameters in under a minute). For accurate liquid panels and confirming anything that looks off, we reach for the Fritz Master Test Kit. Think of it this way: strips for the daily glance, master kit for the deep dive. For a dechlorinator, we use Fritz Complete, though Seachem Prime is also great and we stock several other options in-store. Whatever you use, treat every drop of tap water that goes into the tank. Untreated tap water has chlorine and chloramine that will burn gills.
GH (general hardness) and KH (carbonate hardness) are the advanced rows in the table above. Most kits don't include them out of the box. Lawrenceville tap water sits in a comfortable range for bettas right out of the faucet, so most beginners never need to adjust either one. They start to matter more if you get into planted tanks, breeding, or fancy strains. If you ever see a wild reading or your pH won't hold steady, bring us a water sample. We'll talk you through it and point you at the right adjuster.
Cycle the tank. Cycling is the process of growing two beneficial bacteria in your filter that turn fish waste (ammonia) into nitrite, then nitrite into the safer nitrate. Without cycling, ammonia builds up fast and burns gills. With a cycled tank, your filter does most of the heavy lifting and your water changes handle the rest.
There are two paths from setup to cycled:
- Fishless cycle (ideal). Set up the tank with a heater, filter, and dechlorinated water. Add an ammonia source (a small pinch of fish food, or pure ammonia) plus a dose of FritzZyme 7 to seed your bacteria. Let it run with no fish. Test every few days. When both ammonia and nitrite read 0 within 24 hours of dosing, you're cycled. With FritzZyme 7, usually 7 to 10 days. Without it, more like 4 to 6 weeks.
- Fish-in cycle (what most beginners actually do). Your betta is already in the tank, so keeping ammonia under control matters more than speed. Dose FritzZyme TurboStart 700 right away. It's the faster option and the one we reach for when there's already a fish in the tank. Test every couple of days. When ammonia or nitrite climbs above 0.25 ppm, do a small water change (10 to 25%) and dose your conditioner.
Adding bottled nitrifying bacteria can shave weeks off the wait. We stock several brands in-store, and Fritz is the one we use ourselves: FritzZyme 7 for a standard freshwater cycle (works in roughly 7 to 10 days), and FritzZyme TurboStart 700 when you need it faster. TurboStart is designed for instant-cycle setups when you're adding a fish to a brand-new tank. Other brands work on the same principle, so come ask if you'd like to compare.
The pro move: dose FritzZyme 7 on every water change for the first 4 to 6 weeks. Each water change dilutes the free-floating bacteria, and a small re-dose keeps your colony building back to strength. Once your tests have been stable (ammonia 0, nitrite 0) for a few weeks, your filter holds enough on its own and you can stop dosing.
Bottled bacteria help, but they don't replace water tests. Keep checking.
Weekly water changes. 25% per week is the standard. Don't deep-clean the filter. Rinse the media in old tank water when it gets sludgy. Tap water kills the bacteria you spent weeks growing.
Feeding
Bettas are little carnivores with little stomachs. Their stomach is roughly the size of their eyeball. Feed accordingly.
- 2 to 3 pellets, once or twice a day. That's it. Overfeeding is the #1 way new keepers tank their water quality.
- Pellets we stock and trust: Seachem NutriDiet Betta with Probiotics and New Life Spectrum Betta. Either one will do well, and we have a few other options on the shelf if your fish turns out to be picky.
- One fast day a week. Skip a feeding entirely. It helps digestion and prevents bloat.
- Treats are optional. Frozen bloodworms or daphnia once a week is fine, not required.
If pellets sit on the bottom uneaten, you fed too much. Net them out. Uneaten food rots and spikes ammonia faster than anything else.
Tankmates
Short version: most bettas are happiest alone. The "community betta" is real but rare. Some bettas tolerate snails, shrimp, or peaceful schoolers like ember tetras or kuhli loaches. Many don't. You won't know which one you have until you try, and "trying" sometimes ends badly for the tankmate.
If you want a community tank, we'd rather sell you a different fish than the wrong setup. Come ask. We're a small, family-run shop, and we'd rather lose a sale than send a customer home with a problem.
Signs of Trouble
Check on your betta once a day. You're looking for:
- Clamped fins held tight to the body (stress, water quality, or illness)
- White spots like grains of salt (ich)
- Cottony patches on the body or face (fungus)
- Fins fraying without a snag source (fin rot, usually water-quality driven)
- Lying on the bottom for long stretches when they used to be active
- Refusing food for more than two days
When in doubt, test the water first. Most "sick fish" turn out to be water-quality problems wearing a costume. If your parameters are clean and the symptoms persist, bring us a water sample and a photo. We'll help figure it out.
The Long Game
One of the boys at the shop. They really do recognize you.
A well-kept betta lives 3 to 5 years, sometimes longer. They learn to recognize you. They'll come to the front of the tank when you walk by. They have personalities. Some are mellow, some are tank bullies, some are dramatic about everything.
The boring habits keep them alive: weekly water changes, small meals, stable temperature, lid on the tank. Do those four things and you'll be the keeper most bettas never get.
If something goes sideways, come see us. We'd rather walk you through a fix than sell you a replacement fish.
Stuck on Something?
Bring us a water sample, a photo of the fish, or just the question. We're a family-run aquatics shop in Lawrenceville, and we'd rather help you fix it than sell you another betta.
