Who Gives A Fish Forums

I'm with the majority here, space is definitely a concern for me. I think it's great you're considering the well-being of the fish, and that's exactly why I'd say no to a clownfish in a 5.5 gallon tank.

I've come across the maroon clownfish being described as 'very aggressive', but I'm having trouble understanding what that entails. Would they be aggressive enough to go after a Pterois antennata, for instance (FableRyde)?

To be honest, I'm not sold on keeping two clowns in a 10g. I've never kept marine myself, but from what I understand, clowns are pretty active and get quite large.
