Cryptocoryne parva problems — and how to fix them
Cryptocoryne parva (Cryptocoryne parva) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Extremely slow growth
C. parva is the slowest Crypt and may sit still for weeks. Provide good light, CO2 and root nutrients, then be patient.
Crypt melt
Leaf melt after planting or parameter swings. Keep the rhizome undisturbed and stable conditions; new leaves regrow.
Algae on tiny leaves
Slow growth plus high light invites algae on the small leaves. Balance light with nutrients/CO2 and keep tank clean.
Uprooting/floating
Small clumps dislodge easily before rooting. Plant firmly in fine substrate and avoid strong flow over the foreground.
