My First Tank

[graemespence1]

Hello guys i'm a new fish hobbyist and was wanting some general advice from experts.
I have a aquastart 320 tank which is 28 liter capacity I have had the tank for coming up 3 weeks and I have the following fish
4 Neon tetras
2 Mollies
I being told by my local store not to start a water change till I had the tank for 3 weeks I did a test for PH and nitrites with testing strips and everything is ok should i do the water change soon.
I also wanted advice if I could add more fish or not cause i was fancying a fighting fish but i heard they kill little fish so left that out but wasn't sure if i could put more fish in or not.
I also have a plant in if thats any help as i was told having a plant in helps the fish as well.
I thank anyone in advance for any advice they can give me

Its possible that you could fit a betta in there (fighting fish) but your fist purchase should be an API freshwater master kit , testing kit so you can test your own water. You need to read up on filter cycling in the beginners section, linked in my signature. gluck

If you have yet to get a decent kit, buy once and get salifert test kits not API. The difference is night and day, you hear API users saying "i have never a problem" they never used salifert
