Is your tank a good fit?
See tank setup →A warm, planted freshwater tank gives him room to swim and rest. Plan a home for one male, with regular feeding, water checks and partial water changes.
| Tank space | Start with 5–10 gallons for a standard-size male; choose more room for larger varieties |
|---|---|
| Warm, gentle water | A heater, thermometer and fully cycled filter with low flow |
| Everyday food | Quality betta pellets in small portions |
| Care routine | A daily look at your fish and a weekly water check |
| Places to rest | Live plants and smooth shelters for comfortable resting spots |
|---|---|
| Room to explore | Open swimming space suited to his size and activity |
| A covered top | A secure lid with access to air at the surface |
| Tank mates | Choose for your tank and his temperament · explore options |
A home just for him is a great starting point. Keep male bettas separately. Adding companions calls for more space and a compatibility check. Female bettas also need their own everyday home; see our breeding guidance if you’re planning ahead.

Get his tank ready.
See two tank ideas ↓Prepare and cycle the tank before he arrives. Cycling means growing helpful bacteria in the filter that process fish waste. The setup guide below explains the steps and how to check that your tank is ready.
| Heater & thermometer | Keep the water warm and let you check its temperature |
|---|---|
| Gentle filter | Supports clean water with a flow he can swim in comfortably |
| Plants & smooth decor | Give him places to rest, hide and explore |
| Secure lid | Keeps him in the tank while allowing access to surface air |
| Water conditioner & test kit | Treat tap water for chlorine/chloramine and check water quality |
| Temperature | 76–82°F / 24–28°C |
|---|---|
| pH | 6.8–7.5 as a guide; keep it stable |
| Ammonia & nitrite | Both 0 ppm · check with your water test kit |
| Nitrate | Track the reading to help plan water changes |
| Hardness | The water’s mineral levels; check these when planning tank mates too |
pH describes how acidic or alkaline water is. ppm means “parts per million,” the unit on many water tests.
Check the water before adding him. Complete the cycling process and confirm ammonia and nitrite both read zero. If either is present, follow the setup guide to get the water ready first. Leaves and wood are optional additions; both tank styles still need a heater, filter and regular care.
Follow the betta tank setup guide →A routine you can follow.
Shop betta food →A few regular habits help you keep his water clean and get to know his appetite and behavior.
| Daily | Feed & watch him eat. Offer small meals once or twice a day and watch how he eats. Bettas have very small stomachs, so follow the food label’s portion guide and avoid overfeeding. Remove uneaten food, and check the thermometer and filter. |
|---|---|
| Weekly | Test & refresh the water. Start with a 25% partial water change and adjust to your test results. Treat replacement water with conditioner and match its temperature to the tank. |
| As needed | Clean the filter gently. Rinse dirty sponge or biological filter media in water removed from the aquarium to help preserve the useful bacteria. |
Add variety to his meals.
Use quality betta pellets as his everyday staple. Offer small portions of bloodworms or blackworms for variety, replacing part of a meal rather than adding extra food. Choose aquarium foods from a reliable supplier and thaw frozen food before feeding.
Need help adjusting the routine? Check temperature and water quality first if his appetite or behavior changes. Email Tropicflow for guidance.
Welcome him home.
Read the first 24 hours guide →Have his cycled tank, heater and filter ready before delivery. Keep the first day calm and follow the steps below.
- Bring him indoors
Bring the parcel inside promptly, dim the room and tank lights, and check the unopened bag.
- Help him adjust
Before opening the bag, read Tropicflow’s first 24 hours checklist. Acclimation helps him adjust to his new water. Follow the instructions supplied with your order and keep transport water out of the tank.
- Give him time to settle
Keep the lights low at first. Follow Tropicflow’s guidance to wait 12–24 hours before offering his first small meal.
- Get to know his routine
During the first week, watch how he swims, rests and eats. Keep checking temperature and water quality as he settles in.

Simple answers to help you feel ready for your new betta.
What helps my male betta feel at home?
Start with a cycled, fully aquatic aquarium, a heater and a gentle filter. Keep the water stable at 76–82°F, then add live plants, smooth resting spots and room to swim. Our betta tank setup guide walks you through the basics.
Should I choose a planted or blackwater tank?
Both can make a lovely home. Choose a planted aquarium for fresh greenery, or add aquarium-safe botanicals for a warm blackwater look. Keep heating, gentle filtration and regular care in either setup. Add botanicals gradually and check the water as you go.
How do I choose tank mates for my betta?
A planted home just for him is a great option. If you’d like companions, consider your tank size, water conditions and his individual temperament. Our tank mate notes help you compare fish and shrimp. Watch how they settle in, with separate housing ready if needed.
What if I’d like to explore breeding?
Male and female bettas each need their own everyday home. For experienced keepers planning to breed, prepare a dedicated breeding tank, supervised introductions, separate housing for the adults and food for the fry. When you’re ready to plan, explore our female bettas.
What’s a simple feeding routine?
Offer quality betta food in small portions, following the feeding guide on the package. Suitable frozen or live foods can add variety. Remove any leftovers after feeding to help keep his aquarium clean.
YOUR BETTA’S HOME
Two tank ideas for your betta.
Start with live plants, warm water and a gentle filter. Then choose the look you like.
01 / PLANTED TANK
A tank with live plants.
Live aquatic plants give your betta places to rest and explore. Add a heater and a gentle filter to keep his water warm and clean.
- Live plantsGive him leafy places to rest and hide.
- Gentle filterChoose a low flow so he can swim comfortably.
- Heater & thermometerKeep the water temperature stable at 76–82°F.
02 / BLACKWATER TANK
A tank with leaves and wood.
Blackwater gets its tea-colored look from natural leaves and wood. Use materials made for aquariums, along with live plants, a heater and a gentle filter.
- Almond leaves & driftwoodAdd a little at a time and check your water conditions.
- Plants & swimming spaceLeave space between plants for him to swim.
- Heater & gentle filterKeep the same warm water and gentle flow as a planted tank.
Before adding your betta, cycle the tank so its filter can process fish waste. For both setups, use a secure lid, allow access to air at the surface and keep one male per tank.
