Freshwater Fish Frequently Asked Questions (FAQs)
Can freshwater fish live without a heater?
Most tropical freshwater fish require a heater to stay healthy, as they thrive in temperatures between 74°F and 80°F. However, some species like White Cloud Mountain Minnows, Zebra Danios, and Hillstream Loaches are more tolerant of cooler water. Always research the types of freshwater fish you're keeping to determine the right temperature range.
How to clean a freshwater fish tank?
To clean your freshwater fish tank, follow these steps:
- Turn off electrical equipment (heater, filter, lights)
- Use a gravel vacuum to remove debris and uneaten food
- Perform a 20–30% water change weekly using dechlorinated water
-
Gently wipe algae from the glass and rinse the filter media in old tank water
Regular maintenance ensures healthy water conditions for your freshwater aquarium fish.
How often should I clean my fish tank?
You should perform partial water changes weekly and a thorough clean once every 2–4 weeks, depending on tank size and stocking levels. Overfeeding and overcrowding can lead to faster waste buildup, so monitor your water quality regularly to keep your freshwater aquarium pristine. If you don't have time to do it yourself, visit and contact us for cleaning fish tank service.

Loved my visit to splashy fish. The staff were incredibly helpful/knowledgable and patient. I appreciated their help in selecting the appropriate plants and items for my new betta. Betta a little after a week seems very healthy, energetic and sassy.
I got 12 Congo Tetras over a month ago and they are all alive and colored up beautifully! I love them. All the fish I’ve gotten from SplashyFish have been thriving.
I never expected to be into Kuhli Loaches but holy cow they are the highlight of my tank! So much fun to watch them wiggle around.
Great selection & expertise. Staff was so helpful and knowledgeable.

Bought this plant as a culture on April 5th this year and look at it now left side of the tank from top to bottom trimming tonight

These fish are beautiful, healthy and were perfectly packaged. Shipment arrived quickly, one day I think! Fish still doing well 2 months later! Highly recommend this Seller. All my shipments from Splashy Fish have done well in my planted aquarium.
I really wanted gold guppies so when I found out they had some in stock I went to buy them, when I first looked on their website I was a little hesitant because of the coloration but in person the gold guppies are a lot more vibrant than the pictures show, you can also tell there is so much care for the fish at the store, plus my female gold guppy gave birth the day I got her.
