SPOTTED SILVER DOLLAR (Metynnis Maculatus)

Maximum Standard Length

At least 148 mm.

Aquarium Size

An aquarium with dimensions of 180 ∗ 45 ∗ 45 cm or equivalent should be the smallest considered

Choice of décor is not as critical as water quality and the amount of open swimming-space provided; we have seen very healthy-looking specimens being maintained in completely bare set-ups for example.

That said, a set-up decorated with a sandy substrate, driftwood roots and branches, and perhaps some water-worn rocks and boulders would provide a more natural-looking spectacle. Aquatic plants are best omitted since they will almost certainly be eaten.

It is intolerant of organic waste and require spotless water in order to thrive. Moderate levels of dissolved oxygen and water movement are also recommended, meaning additional powerheads, pumps, etc., should be employed as necessary, while weekly water changes of 30-50% should be considered mandatory.
