Male Galaxy Short-Tail Betta (Betta splendens) is the buyer-friendly name for Petra's Betta spl. male / short tail galaxy listing. It is a single male short-tail Betta from a Galaxy colour/pattern line, so individual speckling, marbling and colour balance can vary from fish to fish.
This is a territorial male labyrinth fish for a mature heated aquarium, not a generic community fish. It is best planned as a display Betta with calm surroundings, gentle filtration and easy access to the surface for air breathing.

|---|---|
| Common name | Male Galaxy Short-Tail Betta |
| Scientific species | Betta splendens |
| Supplier size | XL |
| Fish type | Freshwater labyrinth fish |
| Temperament | Male Betta; territorial and usually kept singly |
| Diet | High-protein Betta pellets, micro granules and small frozen foods |
| Best setup | Heated, covered aquarium with gentle flow, resting cover and open surface access |
Use a fully cycled heated aquarium with stable water, a secure lid and a low-flow or baffled filter. A short-tail male Betta still needs clean water, swimming space, soft plants or smooth decor for cover, and open access to the surface.
A 20 litre aquarium is a practical minimum for a single male, while a larger tank is easier to keep stable. Keep the water warm and steady, around 24-28 C, and avoid strong currents that make the fish work constantly.
Feed a varied, high-protein diet. Quality Betta pellets or micro granules can be the staple, with small frozen foods such as daphnia, brine shrimp or bloodworm offered as variety. Feed modest portions and remove uneaten food.
Male Bettas are territorial. Do not keep two males together, and avoid fin nippers, aggressive fish or bright long-finned tank mates that may trigger displays or fights. Many keepers choose a single-male display tank for the calmest result.
In a larger peaceful aquarium, some male Bettas can live with calm bottom dwellers or small non-nipping fish, but compatibility depends on the individual fish and the layout. Add tank mates cautiously and be ready to separate them if chasing, clamping or stress appears.
The Galaxy Short-Tail Betta is bought for individuality. Galaxy-style Bettas can show speckling, marbling, patches, metallic tones and shifting colour balance from one fish to another. The short-tail form keeps the outline tighter than a long-finned Halfmoon, so the fish often looks more athletic while still carrying strong colour.
Compared with long-tail Bettas, short-tail males can look cleaner and more purposeful in motion. Compared with a Plakat-style Betta, the Galaxy pattern is the visual hook: each fish can feel like a one-off. It is still a male Betta, though, so the display should be planned around one territorial centrepiece rather than a busy mixed group of similar fish.
Choose this Betta if you want a single centrepiece fish for a mature, heated aquarium with gentle flow. It suits keepers who enjoy watching individual behaviour: surface breathing, short patrol routes, flaring displays, resting under leaves and responding to movement outside the glass.
The best setup is calm rather than crowded. Soft plants, smooth cover and a secure lid make the aquarium feel settled, while open access to the surface is essential. Avoid fin nippers and do not keep two males together. If you try tank mates in a larger aquarium, choose them cautiously and be ready to separate if the Betta or the companions show stress.
Add this fish only to a mature aquarium with zero ammonia and nitrite. On arrival, float the bag, acclimate slowly, keep the lights low and avoid heavy feeding on the first day. Watch breathing, posture, fins and appetite during the first week.
