🌍🐠 Blog: What is the optimal tank size for keeping angelfish? 🐠🌍
The overall aquarium size is one of the most important points to consider when choosing a setup but it does depend on which species you are planning to keep. Due to its size, the Altum scalar needs a larger and, very importantly, taller tank than for the Pterophyllum scalare or Pterophyllum leopoldi.
The BMEL (Federal Ministry of Food and Agriculture), which recommends the minimum requirements for the keeping of ornamental fish, states that the aquarium must have be at least 100cm long to keep Pterophyllum scalare. However, a 100cm long aquarium is often only 40cm tall and thus clearly too low! Not to forget that in most aquariums there is a substrate with a depth of 5-10cm!
