How Many Fish Can You House in Each Tank?

When stocking a small aquarium, there is always the temptation to overload the tank with too many fish. However, sticking to the recommended capacity ensures healthy water quality and active fish.

Understanding the \”Inch Per Gallon\” Rule

A common guideline for determining fish capacity is the \”inch per gallon\” rule. This suggests allowing 1 inch of adult fish length per 1 US gallon of water.

For example, in a 5 US gallon tank you could house:

  • 5 x 1 inch fish
  • 2 x 2 inch fish
  • 1 x 5 inch fish

This rule provides a rough estimate but has limitations. The shape, decor, filtration and other factors in your tank can further restrict capacity.

Key Factors Affecting Fish Capacity

Tank size – Small tanks under 10 gallons are best for housing a single betta, shrimp colony or micro school of petite fish. Larger tanks offer more flexibility.

Fish size – Stock small, slender fish for best results. Large fish need much more room.

Tank decor – Decorations, substrates and plants take up swimming space, so factor that into stocking.

Filtration – More powerful filtration supports higher bio-loads but creates strong currents that some fish dislike.

Fish behavior – Aggressive or territorial fish need more personal space than shoaling community fish.

Growth – Baby fish grow quickly, so plan space for their adult size.

With those considerations in mind, let’s examine popular tank sizes and fish capacity.

Stocking 5 Gallon Tanks

Best for:

  • 1 betta OR a single small species like guppies, tetras, rasboras
  • Shrimp colony
  • Snails

Avoid overcrowding by limiting to 1-2 inches of fish maximum.

Stocking 10 Gallon Tanks

Best for:

  • 1 betta plus a few small shoaling fish like neon tetras, harlequin rasboras
  • 1 dwarf gourami or honey gourami
  • Small community of micro fish under 2 inches long

Aim for only 3-5 inches of fish.

Stocking 15+ Gallon Tanks

Best for:

  • Pair of dwarf gouramis
  • Schools of small tetras, danios, rasboras or white cloud minnows
  • Betta sorority for female bettas
  • Community tank with medium tetra species

Limit to only 1 inch per gallon and select peaceful species.

BiOrb and Fluval Tank Sizes

Now that we understand general fish capacity guidelines, how do the tanks sizes of BiOrb and Fluval compare?

BiOrb tanks range from small 5-15 gallon nano models to larger 30-60 gallon tanks. They offer these popular sizes:

  • BiOrb LIFE 15 gallon
  • BiOrb FLOW 30 gallon
  • BiOrb LIFE 60 gallon

Fluval tanks start at 15 gallons and go up to 25 gallons. Their models include:

  • Fluval FLEX 15 gallon
  • Fluval SPEC 19 gallon
  • Fluval SPEC 25 gallon

Based on these sizes, BiOrb provides more choice for nano tanks under 10 gallons, while Fluval focuses on larger 15+ gallon configurations.

Both brands can comfortably house the small fish species, bettas, shrimp, and snails recommended for tanks under 20 gallons. Now let\\\’s analyze how the tank designs and functionality of each compare.

Spotlight on BiOrb Aquariums and Their Features

BiOrb favors round, spherical acrylic tank designs inspired by the natural shape of water bubbles. The curved tanks are stylish centerpieces, though the unconventional shape does impact functionality.

Key Features of BiOrb Tanks

  • Acrylic construction – Made of tough acrylic rather than glass for light weight.
  • Curved shape – Distinctive round shape has aesthetic appeal.
  • Nano to medium sizes – Ranging from 5 to 60 gallons.
  • LED lighting – Integrated LED light capsules in the lids.
  • Multi-stage filtration – Uses air-driven filtration without motors.
  • Starter kits – Most models offer all-in-one starter kits.

Let\\\’s examine some of these features in more detail.

Innovative Use of LED Lighting in BiOrbs

One highlight of BiOrb aquariums is the unique LED lighting built into the tank lid. The lights sit in a raised dome that amplifies illumination while also creating a shimmer effect.

The LEDs generate little heat, keeping water temperatures stable. Models use either warm white or RGB color changing LEDs. The lights are energy efficient and offer customizable intensity.

The Multi-Stage BiOrb Filter System

At the base of each BiOrb is the filtration unit. The patented filtration uses air pressure to drive water through various media stages.

The key steps in the filtration process are:

  • Oxygenation – Bubbles oxygenate the water.
  • Mechanical – Sponge removes debris.
  • Biological – Ceramic media houses beneficial bacteria.
  • Chemical – Activated carbon removes impurities.

This air-powered multi-stage filtration eliminates the need for motorized pumps and creates gentle water circulation. The media stages provide thorough mechanical, biological and chemical filtration to maintain clarity and water quality.

Acrylic Over Glass – Why BiOrb Prefers Acrylic

Most mass market aquariums are made using tempered soda lime glass. It\\\’s inexpensive but very heavy and prone to cracking.

BiOrb instead constructs their tanks from acrylic. Compared to glass, acrylic offers many benefits:

  • Lighter weight – Acrylic is half the weight of glass, making tanks easier to handle.
  • Impact resistance – Less prone to cracking or shattering if knocked.
  • Optical clarity – Transmits light better than standard glass for crystal clear viewing.
  • Thermal insulation – Acrylic is a poor conductor, reducing temperature fluctuations.
  • UV protection – Acrylic blocks more UV light that can trigger algae growth.
  • Color and design – Can be tinted, etched, molded or shaped more easily than glass.

The innovative curved designs of BiOrb tanks take advantage of acrylic\\\’s flexibility while also being durable and scratch-resistant.

Next let\\\’s overview some of BiOrb\\\’s most popular tank models.
