Water quality must be kept high. Strong filtration helps manage waste. Regular water changes are essential.

Decor should be minimal and sturdy. Loose items may be displaced by their movement. Plants may be eaten or uprooted.

They should be kept in groups. Shoaling reduces stress and aggression. Large tanks allow natural behavior.

Tinfoil Barb Diet and Feeding

Vegetable matter is very important. They consume greens and plant based foods. This prevents excessive plant damage.

Frozen and live foods are beneficial. Bloodworms and chopped seafood are accepted. Protein supports growth.
