What kind of fish should i get? ?

Platies

Mollies

Swordtails

Zebra Danios

Barbs

Tetras

PS: Dont go for a Betta Splenden (Siamese Fighter) because they are territorial and will not tolerate other fishes of their own size and colour. Though they are beautifully colourful, they will restrict your choices and options greatly. Also you can't put more than 1 male betta since they do nt tolerate other male bettas in their territory. Dont go for goldfishes either, since they will need more space once they grow to their adult size.

Surf the net and figure out the species whose adult size is 2-3 inches.

Even with your current tank volume, you won't be able to successfully keep more than 4-6 of the fishes I've mentioned above.

If your is a new tank, I suggest you put in 2-4 Mollies as they are hardy fihes and will be excellent for cycling. Research more on 'cycling the tank'.

A Siames Fighting fish

They can come in beautiful colours and can live up to 6 years :)

neon tetras are great fish maybe get a school of 6 or 7 also zebra danios or glofish are great school of 5 or 6

Goldfish

get a couple mollies and platys. you can get guppies too but just males. (or females therenot as pretty though) usually theres a reason why people put amae and a femal guppy together.

You can get mollies, platys and tetras (in groups of more than 6) or a male betta, by itself.

axolotl they r only like 35 bucks off the internet if you find the right people

Koi. There beautiful, live forever, and are baller status... Or piranhas
