Let me start by saying this little gadget has been a lifesaver for my saltwater tank. My tangs and butterflies used to be such divas—sniffing at floating food or letting it dissolve into the water column. This clip changed everything. The grid design keeps frozen mysis shrimp intact long enough for even the shyest fish to nibble comfortably, mimicking how they'd graze on reefs.
Pro tip: Skip the included black mesh (my fish treated it like kryptonite) and use it bare for nori sheets or thawed cubes. The suction cups held strong against my wavemaker's current...for about 6 weeks. Then came The Great Curling Incident—the plastic warped irreversibly no matter how I boiled or reshaped it. Now I DIY-secure it with fishing line.
Where it shines: My puffer goes nuts for scallops pinned in this thing—no more scavenger hunts for uneaten chunks under rocks! But beta owners beware: those bloodworms will escape through the gaps like tiny Houdinis. For larger foods though? Absolute magic. Just wish they'd upgrade to magnetic mounts.
