Frog Spawn, is this the mouth fully open or an open sore?

[MultipleTankSyndrome]

I fed my Frog Spawn reefroids today and noticed what looks like the mouth being WAAAYYYYY open.

Everything look ok?

(sorry for the photo quality. The hard angle to take a photo with the distortion from the tank.)

 

Also I have read mixed things in comments on youtube videos about feeding Reefroids to euphyllia coral. 

Anyone ever experience any issues?

That looks like a mouth to me.

Looks like the mouth. Looks normal to me too.

Looks normal. Reef roids are pretty fine, but as long as you're not trying to squirt them directly into the mouth then the frogspawn should be okay. They generally pull what they want out of the water column. Mine seem to enjoy LRS-They get all puffy after broad feeding the tank.
