Hungry hungry urchins

[MrsPewterschmidt]

I don’t want my pincushion urchin to get hungry but I also don’t want to over feed and I’m not sure quite how to tell. My current tank is 25 gallons, and is 7 months old there is a little algae on rocks and glass but not too much so I figured I’d have to supplement. I added my urchin last week and I feel like she’s gone through a lot of Nori, but I suppose I don’t have a frame of reference for how much she should be eating. This pic she has a shell wrapped in nori that she picks up off the floor of the tank and brings to the top to eat. I don’t think she liked sharing with the hermit crab. How much do your urchins eat?

They've always eaten as much as they can - and then some...

Yea. I figure she’ll eat it if I put it in the tank. I’m just trying to figure how often. Maybe I’ll do 3x per week to start? ‍.

When the seaweed ends up being untouched for a few hours it's usually an indication that you're overfeeding.

Those guys can eat more than you'd think. As long as it is being eaten and the nori isn't breaking down in the tank you're not overfeeding.

Thx @SoFlo Reef and @blaxsun . That makes perfect sense

I toss in some algae pellets every other day or so
