Connor Paterson –
My damselfish love the red seaweed. It’s easy to attach and the fish eat it willingly. The color of the fish has improved noticeably over a few weeks. I remove the uneaten pieces after two hours and it stays clean in the tank.
Sue Marshall –
Works well for my small angelfish. I fold the seaweed before placing it and they graze on it without any issues. It’s a simple addition to the diet and keeps the tank looking natural.
Madeleine Dyer –
Great product for sponge feeders. The fish enjoy it and it’s fully digestible. I use a rubber band to attach it to a rock and it stays in place. No fish have shown any signs of digestive issues.
