Tiny Tanks FAQ

What is a Tiny Tank?

Here at TinyTanks4U.Com we consider the definition of a Tiny Tank to be just about anything from a cup to to a 10 gallon aquarium.

What about water Quality, water changing and filtration?

Water quality is the key to keeping a successful aquarium of any size.
In small tanks water can pollute a lot faster than larger tanks. Fortunately the easiest way to insure water quality is frequent water changes and with a tiny tank thats a lot less work.
Even tiny tanks can be cycled and balanced, just remember to never overstock, never overfeed and change some water every week or so, or any time you notice stress in the fish.
Many tiny tanks will be fine with no filtration at all, but if you need or want filtration try some one of the air driven sponge filters or possibly one of the new extra small power filters that are made especially for small aquariums.

How many fish can I keep in my tiny tank?

The standard rule is one inch of fish to one gallon of tank capacity. That is a very rough guide. For instance if you kept a 10 inch Oscar in a 10 gallon tank you would have trouble very quickly.
But a single 10 inch Oscar in a 100 gallon tank would be very comfortable.
So let's consider the body mass of a 10 inch Oscar equals approximately 150 cubic inches versus the body mass of a single 1 inch Guppy which has a body mass equal to approximately .065 cubic inches. That means that the 10 inch Oscar has a mass equal to 2,307 Guppies. You could logically assume that a 1 gallon aquarium could easily and safely house 23 one inch Guppies!

Most people would think that a little excessive but it does become clearly evident that a 1 gallon tiny tank can comfortably house several 1 inch Guppies, Heterandria or Pygmy Rasboras.
Always consider body mass. In my opinion the "one inch rule" applies to fish with a body mass like Bettas, Platies or Swordtails. If the fish you are wondering about has a body mass similar to those then you should have a good idea of how many fish to keep in a certain size tank.

What types of fish can thrive in Tiny Tanks?

Small Livebearers, Tetras, Bettas, Corydoras Catfish, Zebra Fish, Killifish, Dwarf Cichlids
Never keep large fish like Goldfish, Angelfish or any of the larger Cichlids in a tank smaller than 20 gallons.

What about feeding fish in a Tiny Tank?

Overfeeding is the number one source of problems with any aquarium, but even more so with Tiny Tanks.
NEVER overfeed. I recommend to never feed more than the fish will eat in 30 seconds. And always immediately clean up any uneaten food.

What about lighting a Tiny Tank?

Now days there are LED aquarium lights made just for Tiny Tanks. LED lights produce very little heat.
Normal aquarium lights can overheat a small body of water very quickly, so keep that in mind when you are planning or setting up your Tiny Tank.
Since the depth of our Tiny Tank is usually less than larger aquarium you can many times get by perfectly well on less light.

Isn't bigger better?

Is it? That depends on you. If you prefer a Tiny Tank then it definitely is not.
The only real differences in tank size is that the smaller the tank the faster it will: pollute, cool down or warm up, and/or get overstocked.
But, the smaller the tank the easier it is to: change the water, clean it up, decorate, plant, maintain.

What about temperature stability?

I keep all of my Tiny Tanks in a temperature controlled room in my house. Usually if you are comfortable then the fish will be too. If this isn't feasible for you then a heater might be needed. If thats the case this is one area that you cannot skimp on, you need a quality heater. Many fish have been lost due to a malfuntioning heater.
Always try to avoid sudden drastic temperature changes.
Most aquarium fish will do fine with temperatures within the range of 70 to 82°F (21 to 28°C).
