Help Blue stripe pipefish

[fishoholic]

I checked on him in our fuge (which has a sand bed, LR, cheato and caulerpa, barely any bubbles, and low flow in it) and he's swimming around in and out of the cheato and seems really happy. I looked closely at the cheato and there are lots of pods for him to eat, so hopefully he'll be ok. He wouldn't pose properly for me so I don't know if the bubble is still there or not.
