Galaxy accents across a mixed palette

Galaxy is the name used for the scattered, reflective highlights in this multicolor line. Their density and placement vary, as does the base color beneath them. The Mystery selection offers a different combination in each fish rather than a matching set of patterns.

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.

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.

Betta Care FAQsCommon care questions

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. Learn how to set up your tank →
