Goldfish Tank Mates: Safe & Unsafe Companions Explained
The article asserts that the only truly safe tank mates for fancy goldfish are other fancy goldfish with similar swimming abilities, such as Orandas or Ryukins. It strongly advises against keeping them with faster single-tailed goldfish (Comets, Commons), which will outcompete them for food. Most tropical fish are unsuitable due to differing temperature requirements. Notably, it warns against popular bottom-feeders like plecostomus, which can harm goldfish by sucking on their slime coats. The central message is that avoiding stress, injury, and competition is paramount, making a species-only tank the safest and most recommended option.
