POPETPOP Small Fish Tank Fish Tank Net – Big Size Fish Hatchery Box Separation Net – Fry Hatchery Incubator Mesh with Suction Cup for Aquarium Hermit Crab Cage

Holes too large for fresh fish fry. Maybe a good time out area. Definitely for fish/plants/shrimp larger than a pin head. Holes are about as big as a dimple in a golf ball.You COULD just wrap it with pantyhose.Suction cups are good. You do have to put the suction cups over the pegs AND mesh, as there are no pre-made holes for them to fit through and making larger holes in the mesh is risky. This could cause an issue with the suction cups falling off, but that’s what glue is for.
