What's eating my anubias congensis?

Anubias congensis, a robust mid-to-large aquarium species, faces the same core threats as other Anubias: green spot algae on its persistent leaves, snail grazing, and disturbance or herbivory by fish. Its larger, tougher leaves offer some resistance to snails but provide more surface area for algae to colonize.

Hard green circular spots accumulate on older leaves; heavy infestations turn leaves brown-green and reduce photosynthesis. Balance phosphate levels; introduce nerite snails and otocinclus catfish; remove heavily fouled leaves at the stem.

Surface grazing marks and small holes in leaves; large snail populations can significantly damage foliage. Introduce assassin snails; trap and manually remove pest snails; reduce organic waste that fuels population growth.

Large leaves make attractive targets for nibbling by goldfish, Buenos Aires tetras, or cichlids; leaves are stripped or bitten through. Pair only with non-herbivorous fish; anchor rhizome to hardscape above substrate to prevent uprooting.
