I'm a first time fish buyer with a 25 Lt tropical fish tank?

Question

what sort of fish should i get for a first timer. much appreciated

Answer 1

25 liters tank is not so big.  just 2 platies are fine and they are very colorful and a cory. Or you can get 3 guppies and a cory . That's about it...

Answer 2

That's about a 6.6 us gallon tank

which is not that small, but also not that big

and before i read here somewhere goldfish, they DO NOT belong in a tank that small

you can do the following

if you have a heater

1 male or female betta

3 male platies

3 otocinclus

or

1 male or female betta

6 neon tetras

3 pygmy cories

or if you don't have a heater you can do

6 white cloud mountain minnows

3 panda cories

Answer 3

Stick with simple fish, like Mollies or Tetras, even guppies. The fish store should be able to tell you which ones and how many you should start off with.
