What's eating my cryptocoryne wendtii 'red'?

Cryptocoryne rot / melt

Signs: Leaves turn mushy and translucent after stress events; new red growth disappears rapidly in severe outbreaks.

Control: Keep water parameters constant; do not replant frequently; remove affected leaves; plant will regenerate from rhizome if it remains healthy.

Green spot algae

Signs: Hard green spots on older leaves; this cultivar's dark coloration can obscure early spots until they are dense.

Control: Maintain phosphate above 0.5 ppm; keep lighting moderate; introduce nerite snails for constant surface grazing.

Snail grazing

Signs: Ragged holes in leaves; soft new growth is most vulnerable and can be eaten faster than it emerges in heavy infestations.

Control: Control snail numbers with assassin snails and manual removal; avoid conditions that cause snail population booms.
