The Tiger Oscar 2 is a stunning addition to my 150-gallon tank. It’s very active and shows off its colors well. I’ve had it for six months and it’s healthy and thriving. Just make sure the tank is large enough and avoid keeping it with small or shy fish.
Deirdre Harris –
Great fish with vibrant colors. It’s not the quiet type and needs space to swim. I keep it with a few larger peaceful species. It’s a bit of a challenge to manage, but worth it for the visual impact.

The fish looks impressive, but it’s more aggressive than expected. I had to rearrange my tank layout to avoid conflicts. It’s not for small tanks or beginners.
