Fighting algae or want cover for fry and shrimp? Amazon Frogbit does both at once. Round, spongy leaves sit on the surface while long hair-like roots trail down into the water column — stripping the nitrate algae wants, shading the tank below, and giving shrimplets somewhere to hide. What You’ll Receive Fresh, healthy Amazon Frogbit cultivated and prepared by Aquarium Plants Factory®. Choose the pack size that suits your tank: 3 Plants — Starter Pack. For nano tanks under 10 gallons, or anyone who would rather buy a small culture and let it multiply. Frogbit grows fast, so a few plants become a mat within weeks. 6 Plants — Standard Pack. The usual choice for a 10 to 20 gallon tank. Enough to look established from the start without covering the whole surface on day one. 12 Plants — Value / Breeder Pack. For tanks of 40 gallons and up, or breeders who need cover for fry immediately rather than waiting for the plants to spread.

Water sitting on the leaves makes them yellow and rot, so aim filter outflow below the surface and skip the airstone underneath it. This is the single most common way frogbit fails. Leave an air gap under the lid. Condensation dripping back down does exactly the same damage as spray. Buy for where you want to end up, not where you start. Three plants will reach the coverage of twelve in a month or so under decent light. Pay for the larger pack only if you need the shade or the fry cover now. Thin it every week or two. It doubles fast, and a solid mat of frogbit will shade out every plant beneath it — half to two-thirds surface cover is a sensible target. Yellowing leaves usually mean iron or micronutrients, not light. Floating plants feed entirely from the water column and are the first to show a deficiency. Notes Photos are for reference; leaf size and root length vary with lighting and nutrient availability. Not suitable for tanks with strong surface agitation or high flow.
