I currently have a 90L tank with an ever-growing population of guppies. Unfortunately I don't know many other fish keepers and currently only have the one tank, so the only solution I feel like I'm left with is introducing a predator fish to help control the population.
I'm stuck for ideas of what would be best suited for the job, does anyone have any recommendations for an ideal candidate?
