I'm new to this so please bear with me - I'm so glad I found this informative site. So I've just purchased what the shop assistant described as a brilliant starter tank. Having since discovered this site and read various guides me thinks I was lied to!! Anyhow, I am left with a 6 gallon tank with undergravel filtration. pH = 7.0, temp =25C, and I have just started fishless cycling using food flakes. I shall be buying a water test kit soon to monitor progress. Assuming all goes well, I am after some advice on the best types of fish and numbers of fish for this small tank. I was thinking along the lines of 6 cherry barbs and a couple of platys or a betta- is this too many fish? Any suggestions on what fish and numbers which would be suitable for my tank would be most welcome.
