Give your guppies a colorful habitat—and their newborn fry places to tuck away. Group several AquaNest mops to create dense, movable cover without waiting for plants to fill in. Lift them out for easy cleaning, then put them right back.
Use several mops as removable bottom cover
Group several non-floating mops to create a removable, substrate-like patch along the bottom of a suitable guppy tank. Combine lower cover with other sheltered areas where your fry gather. Leave feeding space and water flow between patches; adults can still reach exposed fry.
Easy cleaning is part of the setup: check for eggs and animals, lift an empty mop by its center tie, swish it in removed aquarium water and siphon the exposed bottom. No soap. See the multiple-mop bottom-cover guide.

Why cover matters for newborn guppies
Guppies give birth to live young, so the mop’s job here is cover rather than egg collection. Newborn fry can slip among the strands and break the line of sight with adult fish. Place cover where you see the babies gathering, with gentle flow and open water nearby.

Keeping adults and fry in the same tank
Mops can be part of a colony-breeding setup: adults stay in the aquarium while fry find shelter among dense cover. Add more than one covered area if space allows, and make sure suitable fine food reaches the youngsters. Adult guppies can still eat fry; a separate grow-out tank offers more control when saving the largest number is your priority.
Cover that works with your layout
Choose a floating mop for hanging strands near the surface or a non-floating style for other positions. Use the suction cup to keep the mop where you want it, away from filter intakes. Leave swimming space for adults and inspect the tank daily as your guppy population grows.
Easy to lift out. Easy to clean.
During routine tank maintenance, lift the mop out carefully, swish it in removed aquarium water to release trapped debris, and return it to position. Check for fish, fry or shrimp among the strands first. No roots to replant and no substrate to dig through. See our step-by-step mop cleaning guide for deeper cleaning between uses.
Pair your mop with good feeding, suitable filtration and regular water maintenance. Read our fry-cover guide for more placement ideas, or Aquarium Co-Op’s guppy care guide for general husbandry.
