Betta Fish Care Sheet
Betta Fish Care Sheet: The Ultimate Guide
The Betta fish (*Betta splendens*), or Siamese Fighting Fish, is a tropical pet requiring specific, high-quality conditions to thrive. Following these essential guidelines will help your Betta achieve its full lifespan potential of 2 to 4 years or more.
I. Essential Tank Requirements
Crucial Requirement: Never house a Betta in an unfiltered, unheated bowl or container under 5 gallons. These conditions drastically shorten their lifespan.
| Item | Requirement | Notes |
|---|---|---|
| Minimum Tank Size | 5 Gallons (19L) | Necessary for stable water parameters and adequate swimming space. |
| Water Temperature | 76°F – 82°F (24.5°C – 28°C) | A reliable heater is mandatory. Colder water weakens the immune system. |
| Filtration | Gentle Flow Filter | Must be low-current. Sponge filters or baffled HOB filters are ideal. |
| Lid/Hood | Required | Bettas are excellent jumpers and require a secure lid. |
II. Water Quality & Parameters
Maintaining pristine water quality is the single most important factor for Betta health and longevity. All water must be treated with a dechlorinator.
| Parameter | Ideal Range | Action if High |
|---|---|---|
| Ammonia (NH3) | 0 ppm | Immediate 50% water change. Indicates an uncycled tank or heavy waste load. |
| Nitrite (NO2) | 0 ppm | Immediate 50% water change. Indicates a failing or immature filter cycle. |
| Nitrate (NO3) | < 20 ppm | Perform a weekly water change to remove. |
| pH | 6.5 – 7.5 | Bettas tolerate a wide range, but stability is key. |
Understanding the Nitrogen Cycle is vital for all fish keeping.
III. Diet & Feeding Guidelines
Bettas are carnivores. Overfeeding is one of the quickest ways to cause fatal illness (swim bladder disorder, constipation, or organ damage).
- Amount: Feed only what the fish can eat in less than 2 minutes. This is typically 2-4 pellets, twice per day.
- Staple: High-quality Betta pellets (look for protein as the first ingredient).
- Treats (1-2x/week): Frozen or freeze-dried Bloodworms or Brine Shrimp.
- Warning: Never feed flakes or human food.
IV. Decor, Plants, and Enrichment
Provide a rich environment with cover, rest, and low-stress elements.
- Plants: Use live plants (Java Fern, Anubias) or silk/soft plastic plants. Sharp plastic decor will tear delicate fins and cause infection.
- Resting Spot: A Betta leaf hammock or large leaves near the surface allow them to rest without swimming far for air.
- Water Conditioning (Tannins): Add Indian Almond Leaves (Catappa) or liquid blackwater extract. The tannins released mimic their natural habitat, reduce stress, and have natural antifungal properties.
V. Special Care by Fin Type
Different fin types have different vulnerabilities, primarily related to their ability to swim and fight infection.
| Fin Type | Examples | Key Vulnerability & Action |
|---|---|---|
| Long-Finned | Halfmoon, Veiltail, Super Delta | Vulnerability: Heavy fins lead to swimming exhaustion. Action: Ensure the filter flow is extremely gentle. |
| Short-Finned | Plakat, Wild-Type | Vulnerability: Least vulnerable, highly active. Action: Can handle more flow and require more open swimming space. |
| Over-Finned | Double Tail, Rose Tail | Vulnerability: Highest risk of fin rot and tearing. Action: Must have absolutely pristine water quality and only silk/live plants. |
VI. Tank Mates & Social Rules
- Primary Rule: NEVER house two male Bettas together.
- Recommended Mates (10+ Gallons): Snails (Nerite, Mystery), Amano Shrimp, Pygmy Corydoras, or small, non-aggressive Tetras (Ember, Neon).
- Avoid: Fin-nippers (Tiger Barbs), aggressive species, or other colorful fish that may resemble a rival male.
