Hi there I am looking for some suggestions on what fish I can house in my 40 Litre Tropical Aquarium. (I have attached an image) 13453295 10209702222382035 2091767718 o I do have a couple of fish in mind e.g. Tetras and guppies however I am totally open to new suggestions. I am also open to adding some new/different decorations if this would benefit any potential future fish. My tank has been up and running for only a week, so I am not looking to add any new fish yet until it has fully cycled. I am simply exploring what type of fish people may have had in a similar sized aquarium and what worked well/not so well for them. I really appreciate everyone's suggestions.
