Hi all Completely new to the forum so please bare with me! Hoping to start keeping some pet fish, I’ve been given some equipment but to be honest I do not know what I have an what I don’t! I also don’t know how many litres my tank holds. I’ve (hopefully) attached some photos.. can anyone shed light on what I have and what I’m missing? & what kind of fish a tank like this would be suitable for? Any help is much appreciated thank you!
