The best algae grazer for planted tanks. Tiny and completely peaceful. Must be kept in groups of 6 plus. Sensitive to ammonia and needs a mature established tank to thrive long term.

๐Ÿฝ๏ธFeeding

Algae and biofilm already in the tank. Supplement with algae wafers and blanched zucchini or cucumber regularly.

๐ŸฃBreeding

Egg depositors. Lay eggs on plant leaves. Rarely breeds in captivity but it is possible with the right conditions.

๐ŸคGood tankmates

Shrimp, Small tetras, Corydoras
