A rimless fish tank is an aquarium built without the plastic or metal frame (rim) that traditional tanks have. This design creates a clean, modern, and open look, making the glass edges visible and unobstructed. Many aquascapers prefer rimless tanks because they showcase the aquascape without visual distractions.

It depends on your priorities:

– Rimless tanks look more modern and elegant.
– No rim means nothing blocks your view.
– Often made from thicker, high-clarity glass.

However, they can be more expensive and may require extra care when moving or cleaning.

Rimless aquariums are available in many sizes, from small desktop nano tanks (2–5 gallons) to large display tanks (50+ gallons). Popular sizes include:

- 2, 3, 5 gallons (great for bettas, shrimp, or small aquascapes)
- 10, 15, 20 gallons (ideal for planted aquariums or small community fish)
- 30–60 gallons (for more complex setups or larger fish species)

Yes, when made with proper glass thickness and high-quality silicone seams. Manufacturers use thicker glass to handle water pressure without the extra support of a rim. Always buy from a reputable supplier and place the tank on a level, supportive stand.

Most rimless aquariums are made from:

– For a crystal-clear view without the green tint of regular glass.
– Non-tempered is easier to drill for filters or plumbing, while tempered is more impact-resistant.

Not necessarily, but it’s recommended for:

- Preventing fish from jumping out.
- Reducing evaporation.
- Keeping dust and debris out.
Many hobbyists use clear glass lids or mesh covers to maintain the open look.
