Gracilaria Hayi?

This doesn't look like Hayi to me. The blades look too wide, but maybe its the photo perspective. Unfortunately, I can't currently ID this.

[A beautiful species of Gracilaria featuring rigid, flame shaped branches that form a tight symmetrical bush. It is lightly calcified so the addition of calcium is recommended. In shallow water it is often found in very large clumps covered in colonial tunicates or encrusted with epiphytic bryozoans. The coloration varies between deep crimson red to bright orange depending on the amount of light provided. It features a small holdfast that can be attached to rocks or left as a free floating specimen if desired. Overall it is undemanding and will grow well under a variety of conditions even in low flow environments. Due to its lightly calcified branches it is not known to be very palatable to fish or invertebrates.]

It looks like Gracilaria Hayi to me. Is it lightly calcified?
