The Tiger Oscar arrived healthy and active. It has quickly adapted to the tank and is very visible in the water. The coloration is vivid and it swims with confidence. Only needs a large tank, which we have provided.
Grace White –
We’ve had the fish for three months now. It’s not the most social, but it’s strong and stays active. We keep it with larger, non-aggressive fish. Feeding is straightforward and it eats well.
Melanie Sharp –
Great purchase. The fish looks exactly as described. It’s a centerpiece in our 100-gallon tank. We’ve noticed it’s more active at night and enjoys the surface area.
