Tropical aquarium fish small

Stocking a Small Aquarium

Smaller aquariums in the range of 10-20 gallons are the ideal size for the serious beginner. In addition to being economical, they are compact enough not to take up too much space in your home or office, but large enough to provide the perfect habitat for some of the most intriguing and beautiful miniature species.

When stocking your small aquarium, think scale: a community of tiny, active, and colorful tropical fish can make even the smallest setup appear grand.

Stock for balance and visual interest
Selecting your small community is a matter of compatibility, behavior, and beauty. Choose peaceful species, keeping in mind each may prefer a different diet, swimming area, and activity level. Use this diversity to create a balanced, healthy community that's both interesting to observe and easy to care for.

Schooling Fish
The majority of your community should consist of schooling fish of the same species. Schools create repetition of pattern and color, harmony of movement, and the illusion of several fish acting as one mind. The effect is both calming and dramatic. Ideal schooling fish include Rasboras, Danios, White Cloud minnows, and smaller varieties of Tetras.

Showcase Fish
In contrast to a unified backdrop of schooling fish, choose one or two fish that stand out in both appearance and behavior. These fish become the "stars" of your community. Dwarf or Pygmy Gouramis make interesting choices for small aquariums, though extra care must be taken to keep pristine water conditions.

Algae & Detritus Eating Catfish
Put some fish in your community to work on cleanup duty. While many algae-eating Plecos grow far too large for small aquariums, the Dwarf Otocinclus Catfish is sized just right. This hardy worker seems endlessly busy, seeking out any plant or structure with a hint of algae. Another small catfish, the Cory Cat, patrols the bottom of your aquarium, vacuuming up excess fish food and plant leaves before they can rot and turn into dangerous ammonia and nitrite.

Remember to research the specific requirements for each fish you choose, including water conditions, habitat, compatibility, and diet. Frequent, partial water changes and regular testing are especially important in compact ecosystems.

Fish question

by Ivarsgirl

I'm fairly new to keeping tropical fish but I love it :)
I have guppies, danios, mollies and plecos together in a tank. I noticed today at petsmart the guppies and mollies had a note "requires aquarium salt" but the danios and plecos did not. I picked some up.
I assume the plecos and danios will not be harmed by the salt if I put it in for the benefit of the others - but you know what happens when you assume.
Anyone out there know if it's OK to put it in?

Easy in a way...

It is easier to care (longterm) for a larger tank than a smaller one, but it still takes work.
First, don't mix tropical fish and turtles. They have different needs (in terms of tank set-up) and anyway, the turtles will just snack on your fish. So figure out what you want in the tank first.
Starting a new fishtank takes a bit of time, because you shouldn't just go out, buy a tank and some fish and set it up all at once. Talk to some people at aa aquarium specilty store (please not a petsmart kind of place-they are clueless) an they will help you figure out your equipment needs, tank set-up etc.
