Aquariums
Learn the essentials of aquarium keeping—from tank setup and filtration to water chemistry and fish care. These quizzes help you review common terms, best practices, and troubleshooting ideas for both freshwater and marine tanks.
Quizzes
Community fish compatibility and stocking
Build a peaceful community tank by learning which fish mix well—and which combinations cause stress, fin-nipping, or worse. This quiz covers temperament, size, water parameters, and stocking density decisions for popular freshwater species. Pick your question count and difficulty, then test your compatibility instincts with no timer pressure.
Aquarium filtration: types and maintenance
Get confident with aquarium filtration by comparing sponge, HOB, canister, and sump setups, then learning how to maintain them safely. This mixed-difficulty quiz covers flow, media choices, cycling, and troubleshooting so you can keep water clear and fish healthy.
Freshwater tank cycling and testing basics
Build confidence with the nitrogen cycle and the water tests that prove it’s working. This quiz covers cycling methods, ammonia/nitrite/nitrate readings, and what “safe” looks like for fish and plants. Expect practical scenarios, common mistakes, and clear testing basics for everyday freshwater tanks.

What you’ll practice
These Aquariums quizzes focus on practical knowledge: cycling a tank, maintaining stable water parameters, choosing compatible species, and preventing common health issues.
You’ll also review key equipment and concepts like filtration types, lighting, substrate choices, and routine maintenance habits.
How the quizzes work
Each question has 4 answer options and there’s no timer, so you can think through scenarios like algae blooms, cloudy water, or stressed fish behavior.
Quiz difficulty and length can vary across the set—some quizzes are quick refreshers while others go deeper into terminology and care details.
Aquarium facts and context
Aquariums are small ecosystems where biological filtration (beneficial bacteria converting ammonia to nitrite and nitrate) is central to keeping fish safe. Even minor changes in temperature, pH, or stocking levels can shift the balance, which is why consistent testing and gradual adjustments matter.
- Identify core water parameters (ammonia, nitrite, nitrate, pH) and what they indicate
- Match equipment to needs (filters, heaters, air pumps, lights)
- Recognize signs of stress or disease and common causes
- Understand cycling, stocking limits, and compatibility basics
- Apply maintenance routines: water changes, gravel cleaning, and filter care
