💧 Freshwater Fish: Your Journey Begins Here

Freshwater tanks are the classic starting point for many aquarists, offering a vibrant array of species and relatively straightforward care.

Community Tank Harmony

Choosing the right tank mates is crucial for a peaceful environment. Before you introduce any new species, always research their temperament, adult size, and preferred water parameters.

• Top Picks for Beginners: Looking for tranquility? Species like Neon Tetras, Guppies (see our Guppy Fish Care Sheet), and Corydoras Catfish are excellent community fish known for their peaceful nature.

• The Big Question: Which Fish Can Live Together in a Community Fish Tank? The general rule is do not mix aggressive predators with smaller, slower-moving fish. Also, be wary of fin-nippers, which can stress out long-finned species like Angelfish or Bettas.

❤️ Health & Wellness: A Proactive Approach

Preventative care is always easier than treating illness. A healthy tank starts with good water quality and observation.

Common Fish Illnesses & Care
