I have a 110 litre tank and I would like a fish that isn't aggresive, can live on its own without its own species but with other types and is lively.
Thank you.
Its tropical
I am a little unsure about the question. Do you already have fish in the tank, and want to add one more? If that is correct, please list the fish already in the tank.
Is your tank empty, and you want each fish to fit that description?
