Betta fish are naturally found in Thailand and Cambodia, usually in small ponds, rice paddies and slow moving rivers with lots of thick vegetation. To be able to survive in these areas, where the water often dries up to small puddles in the dry season, Betta fish have developed the ability to jump from puddle to puddle and breathe small amounts of oxygen from the surface using something called the
labyrinth organ.
This is likely what spawned the myth that they can live in small amounts of unfiltered water, like cups and vases.
Betta requirements
Contrary to belief spread mainly by pet stores, Betta fish cannot live in a cup, and won’t ‘freak out’ in larger spaces. They are tropical fish that require a heated, filtered and preferably rectangular tank of at least 5 gallons with a lid. Bettas can breathe air at the surface, so they should always have the possibility to do this. To make them feel safe, a planted tank and calm tankmates are recommended.
Tanks like the ‘Betta peace lilly’, wall mounted bowl, tiny “aquaponics systems” and “self cleaning tanks” are
not proper living space for a betta and should always be avoided.

The Betta’s upturned mouth reveals what it likes to eat in the wild: insects that have fallen in the water. Mosquito larvae, zooplankton and occasionally small amounts of vegetable matter are also in the wild Betta’s diet.
In captivity, Bettas should be fed a varied diet, consisting of high quality Betta pellets like
Omega One Betta Buffet Pellets or
New Life Spectrum Betta Formula and other foods containing animal protein, like mosquito larvae, bloodworms, brine shrimp and small live shrimp.
Be sure not to overfeed your Betta. Although they are great at begging for food and seem hungry all the time, they only need a small amount of food once or twice a day. Skipping a day, for example when you’re away, is not a problem.

Although most guides list building bubble nests as the best indicator for whether a betta is happy and healthy or not. However, even sick bettas in tiny cups will sometimes do this, so whether your betta makes bubble nests or not says nothing about its condition. A healthy, happy Betta is curious and active, and will usually flare when confronted with a mirror. Other signs that your Betta is doing well are begging for food, getting excited when you enter the room and patrolling the tank.
When provided with the right kind of aquarium, Bettas are gorgeous fish with a huge personality towards both their owner and their tankmates. If you’d describe your Betta as ‘boring’, then there’s probably something wrong. Sick or unhappy Bettas show symptoms like lethargy, paleness, fins rotting/”melting” away, hiding, scratching or being skittish.

As for your goldfish:
Tank size 100 gal (380L) per fish
Temperament Peaceful
Diet Omnivore
Temperature Seasonal
pH 7-8
Name:
Carassius auratus, single tail goldfish. This includes common goldfish, comet goldfish, and shubunkin.
Goldfish natural habitat:
The goldfish as we know it does not naturally appear in the wild. Its ancestor, the Prussian carp, is mainly found in Asia.
Goldfish appearance:
Single tailed goldfish can be told apart from fancy goldfish by their tail (surprise, surprise), but also by their body shape. While some fancy goldfish types do have a single tail, they have a much rounder body than actual single tail goldfish. Single tails come in almost all colors, including yellow, orange, green/brown, calico and white. They have a long, torpedo shaped body that is similar to that of the Prussian carp and can grow quite large; up to 12 inch (30 cm) is sometimes seen!
Determining the gender of a single tailed goldfish can be a challenge, especially when they’re kept in a pond. However, it’s not impossible! Most males grow small white bumps on their operculum and pectoral fins; it has many a beginning goldfish keeper worried about disease, but it’s actually just a sign that your goldfish is ready to breed. During breeding season, you’ll also notice the females getting much rounder and being chased continuously by the males.
Goldfish requirements:
Single tail goldfish requirements come as a shock to many people. These fish can grow
very large, which makes them unsuitable for life in a goldfish bowl or aquarium. Contrary to what most pet stores will tell you, they will
not grow to the size of the container they are kept in. As mentioned before, if you’re wondering why exactly bowls and small tanks are not a good home for your goldie, check out
Why goldfish bowls should be banned.
So what is a good environment for your single tail goldfish to thrive in?
A pond!
Unfortunately, due to their size, activity level and need to live in groups, these fish are not aquarium fish. They should be kept in a pond year round with at least 2-3 other goldfish. The pond, at least around 300 gallons (1135L), should be filtered with
a pond filter that has room for biological filter material or very lightly stocked and filtered using lots of aquatic plants. I’d recommend the first option, because it’s much easier to keep a pond balanced with a good filter.
If you filter your pond well and go for around 100 gallons (380L) per goldfish, the fish will be able to thrive and grow to their true potential without the ammonia levels getting out of control.
And if that's not the type of goldfish you have, than you must have Fancy goldfish which surprise are even more difficult to keep
