That’s good that you will be asking questions before just jumping at a new tankBeen thinking and I agree, theres too many fish in such a small tank. If not the waste, ammonia issue it's also the stress and general space for them to swim in is not enough. I'm buying a 100 litre tank tomorrow so will probably be asking questions re cycling etc.
Thanks for input etc
Ask as many as you like but there’s a good section on this forum about cycling, feel free to read that in the mean time
