Seasonal Species Guide
Discover the best pets to welcome home each season. Find the perfect timing and species for you.
The best time to breed, grow, and welcome animals shifts with seasonal factors like water temperature, air temperature, and daylight hours. Matching the timing reduces shipping stress, improves breeding success, and helps you welcome healthier specimens. This guide covers care points (temperature, water changes, light, humidity) and recommended species for each season — for medaka, goldfish, tropical and marine fish, coral, and reptiles.
🌸Spring (March - May)
Spring is when animals are most active. With breeding season arrives, now is the best time to find your ideal pet from breeders.
15-25°C (59-77°F)
50-60%
Recommended Species & Categories
Medaka — Spring Breeding Season
Medaka spawn once two conditions align — water above 18°C and daylight of 13+ hours — which naturally occurs in spring. For active breeding, aim for 20-25°C. Popular varieties like Youkihi, Miyuki, and Tricolor are arriving as fresh fry.
Coral — Stable Temperature Window
Spring minimizes temperature stress during shipping. Perfect timing to add SPS and LPS corals to your reef tank.
Reptiles — Baby Season Starts
After winter cooling, spring brings breeding and hatching. Ball python, leopard gecko, and bearded dragon babies are available.
Tips for This Season
Tips for Spring Livestock Shipping
In March, request insulated packaging due to temperature swings. From mid-April, room temperature shipping is usually safe. Communicate your preferred delivery time to the breeder.
How to Welcome New Arrivals
Don't rush to place arrivals immediately. Fish need water acclimation. Patience is key.
Don't Miss Spring Sales
Many breeders run sales during spring breeding season. Add favorites to receive price drop notifications. Look for bundle discounts.
Care Tips
- Breeding season begins — Most animals become active. Best time to find listings from breeders.
- Ideal time for repotting and dividing plants — Complete before active growth begins.
- Watch for water temperature changes — Adjust heaters gradually.
☀️Summer (June - August)
Summer is peak season for aquatic life. Medaka breeding peaks, and insects are perfect for summer projects — while corals and tropical fish need careful heat management. Don't miss our heat management tips.
25-32°C (77-90°F)
40-70%
Recommended Species & Categories
Medaka — Peak Breeding Season
At 25°C+, medaka spawn almost daily. Master fry management, feeding, and selection for variety improvement.
Insects — Beetle Season
Japanese beetle season is here. Collect and breed domestic species, or buy exotic specimens directly from breeders.
Tropical Fish — Summer Water Management
Summer heat management is critical. Use fans and chillers to maintain optimal temperatures for breeding popular species.
Coral — Heat Management is Top Priority
Summer's strong light and nutrients can fuel coral growth, but heat management comes first. Most corals prefer 24-27°C; sustained temperatures above 28°C raise the risk of bleaching. Use a chiller, cooling fans, and good flow to keep temperatures down before pushing frag growth.
Tips for This Season
Summer Heat Management
Use cooling fans or chillers for tanks. Keep reptiles in AC rooms. Temperatures above 40°C can be lethal.
Summer Shipping Precautions
Insulated packaging with ice packs is essential. Choose morning delivery with the shortest transit time. Avoid shipping during extreme heat waves.
Starting a Hobby This Summer
Medaka and beetles are perfect starter pets. Consult breeders for the best specimens and equipment recommendations.
Care Tips
- Heat management is critical — Use air conditioning and cooling fans.
- Watch for water quality deterioration — Increase water change frequency.
- Great time to start a new hobby — Medaka and insects are beginner-friendly.
🍂Autumn (September - November)
Autumn means winter prep and great deals on post-breeding season specimens. Get ready for the cooler months ahead.
15-25°C (59-77°F)
50-60%
Recommended Species & Categories
Reptiles — Winter Prep & Cooling
Plan cooling schedules for breeding. Feed well to build reserves, then gradually reduce temperature and photoperiod.
Goldfish — Autumn Conditioning
Show season conditioning. Enhance feed quality for body shape and color. Last growth sprint for young-of-year fish.
Birds — Chick Season
Spring-summer chicks are now ready for hand-feeding. Get cockatiel, budgie, and finch babies directly from trusted breeders.
Tips for This Season
Winter Preparation Checklist
Check heaters, replace thermostat batteries, and prepare insulation by October. Equipment failure in winter can be devastating.
Autumn Sale Tips
Breeders often have surplus stock after breeding season. Follow your favorite breeders and enable notifications for deals.
Care Tips
- Time to prepare for winter — Inspect heating equipment early.
- Great deals on post-breeding season specimens.
- Autumn-growing plants enter active growth — Ideal for repotting.
❄️Winter (December - February)
Winter is the season to rediscover indoor keeping. Heated tanks for tropical fish and coral, and reptile cooling management.
20-28°C (68-82°F) (heating required)
40-60%
Recommended Species & Categories
Tropical Fish — Indoor Aquarium Season
Cold winters are perfect for settling into indoor aquariums. Most tropical fish stay stable year-round at 25-28°C with a heater, and breeding is achievable. Winter raises heater load, so check the thermostat and choose equipment with capacity headroom. A great time to add new tankmates.
Marine Fish — Winter Stability
In winter, heater-controlled tanks stay more stable, reducing temperature stress and the outbreaks it triggers. Note that marine white spot does not simply disappear at low temperatures, so always quarantine new arrivals for a few weeks before adding them. Start with hardy beginner fish like clownfish and firefish.
Goldfish — Outdoor Wintering & Low-Temp Care
Goldfish are hardy; kept outdoors, they slow down and enter winter dormancy as the water drops to around 5°C. Their digestion also slows, so withhold feeding (generally no food below 10°C) and keep water changes minimal. Watch for surface freezing and oxygen depletion, maintaining aeration as needed. Indoors, a heater above 15°C keeps them active — but avoid sudden temperature swings.
Tips for This Season
Winter Heating Solutions
Combine overhead heaters, heat panels, and heat bulbs with thermostats. Keep hand warmers and styrofoam boxes as power outage backup.
Winter Shipping Tips
Insulated boxes with heat packs are essential. Specify daytime delivery and the shortest route. Consider delaying shipping when temps drop below 5°C.
Winter Shopping Opportunities
Year-end sales and winter bonus events offer great deals. Medaka and insects are available at off-season prices. Start preparing for spring!
Care Tips
- Heating is essential — Keep backup heaters and heat mats ready.
- Rediscover indoor keeping — Enjoy heated tanks and terrariums.
- Year-end sales and off-season prices offer great deals.
Note: Optimal temperature and humidity vary significantly by species. Manage conditions according to the specific needs of your animals/plants. Consult breeders or specialty shops if unsure.
