Which aquarium for the Redhook myleus?

Specific aquarium preferable . In a community tank, plan a 1000 L tank (220 Imp Gal / 264 US Gal). Just like the Silver Dollar, the Redhook myleus is an avid plant eater. Therefore, avoid plants that are too thin that your fish would eat on the spot. Instead, prefer very robust plants with large leaves and large dimensions such as Echinoderms. However, even these hardy plants will need to be replaced regularly. A final alternative to this problem is artificial plants.

Peat filtration is recommended as well as a high flow rate to ensure good oxygenation.

Finally, install hiding places and floating plants that will shade areas of the aquarium and reassure the Redhook myleus.
