Aquarium Setup
Tiger Silver Dollars are active, large-growing schooling fish that need plenty of open swimming space and a securely covered tank, as they can be skittish and may jump when startled. A spacious aquarium with strong filtration keeps these big-bodied fish healthy.
Recommended setup:
- 75+ gallon aquarium (larger for groups)
- Open swimming areas with subdued lighting
- Driftwood, smooth rocks, and hardy or artificial plants (they nibble soft live plants)
- Strong filtration and regular water changes
- Soft, slightly acidic to neutral water
Diet & Feeding
Tiger Silver Dollars are primarily herbivorous omnivores with a strong appetite for plant matter. A varied, vegetable-rich diet keeps their bars bold and their digestion healthy.
- High-quality vegetable flakes and pellets
- Blanched vegetables such as zucchini, spinach, and peas
- Spirulina and algae-based foods
- Occasional protein treats like bloodworms or brine shrimp
Tank Mates
Peaceful despite their size, Tiger Silver Dollars do best with other large, even-tempered community fish. Good companions include:
- Other Silver Dollars
- Bala Sharks
- Tinfoil Barbs
- Severums and other peaceful South American cichlids
- Large Plecos
- Larger Rainbowfish
Avoid:
- Small tetras and nano fish (may be intimidated)
- Aggressive or fin-nipping species
- Delicate live-planted aquascapes (they will graze on soft plants)
Schooling Behavior
Tiger Silver Dollars are happiest in groups of five or more. Kept in a proper school they are calmer, bolder, and display their natural shimmering, synchronized swimming. Single or small numbers of fish tend to be shy and stressed.
