6103. Caring for a 3-month-old red-eared slider in an apartment.

 

 SINGAPORE - 24 JUN 2026: A small plastic tank with water to house a 3-MONTH-OLD RED-EARED SLIDER. it has a green basking platform (R), 50-watt heat lamp (R, corner), submersible heater set at 28 to 30 degrees C set on for 24 hours and a water filtration pump with sponge and charcoal filters which must be replaced 1-2 monthly. The set up is in a pet shop selling sliders.

 

 

Caring for a 3-month-old red-eared slider in an apartment requires a 15 to 20-gallon tank (upgrading to 40+ gallons as it grows), a submersible water heater (76°F -- 85°F water), a dry basking dock, and specialized UVA/UVB and heat lamps. Feed them daily with high-quality pellets, insects, and dark leafy greens. FEED them in a separate tank to keep the main tank water clean.

Tank Setup & Water Quality

• Tank Size: Start with a minimum 15 to 20-gallon tank, but keep in mind they grow rapidly and need 10 gallons of water per inch of shell length. [1, 2]
• Water Depth: The water should be deep enough so the baby can easily flip over if needed, usually around twice the length of the shell.
• Filtration: Turtles are extremely messy. Use a high-quality submersible or canister filter rated for twice the volume of your tank to keep ammonia and nitrate levels safe. [1, 2]
• Maintenance: Perform weekly 25% water changes. According to a consensus among keepers on Facebook, you should do 50% changes when nitrates are high, but never clean the filter media and change the water during the same week to protect beneficial bacteria. [1, 2]
• Substrate: Use either bare bottom or large river rocks that are bigger than the turtle’s head to prevent choking. [1]
