Frequently Asked Questions (FAQs)
1. Are round fish tanks good?
In a rounded tank sufficiently large for a fish to live in, the curvature is much less than in a tiny one, and would therefore distort the surroundings much less if at all. The issue of hiding spaces is worth noting, as another poster brought up, but in a sufficiently large tank, that's easy to solve.
2. What shape aquarium is best?
Rectangular fish tanks are best for better water quality and overall fish health. This is due to the larger surface area between air and water which allows for more efficient gas exchange.
3. Can fish live in round bowls?
Fish Bowls Restrict Oxygen Levels Undersized housing is bad for fish (or any animal) in any situation. However, bowl-shaped vessels are especially faulty. Part of this has to do with how the surface area of the air-water interface changes as you fill them.
4. Why are large aquariums circular?
Yes, it does matter. The primary reason is territory. Many fish are territorial and want to establish their own areas in the tank. The other is swimming space as some fish get stressed out if they cannot swim openly back and forth in the tank.
