Why does my hammer coral look like this?

[Mitch0928]

This is my bicolor hammer coral. For some reason he almost looks like it is stretched out and not happy. When I first got him, he was perfectly fine and looked extremely healthy just like my branching frogspawn. Overtime he seems to have looked stressed and stretched out and his tentacles seem very skinny. Is there something wrong and if so can someone please help me

parameters:
dkh-9
Cal-450
Mag-1400
Nitrate-0
Phosphate-.2ppm
Salinity-1.025
Temp-80

Everything else is extremely healthy

how long have you had this coral in your tank?
Also, I think your nitrates are too low

It’s been in the tank for about 2 months. And how can I raise my nitrates?

I wouldn't worry too much, everything else looks nice and healthy. Maybe try slightly different flow or move him to slightly higher lighting.

Ok. I will try that!

just simply feeding more while watching your phosphate level
