Removing hydra from shrimp/snail tank

[u/Vindamant]

10 gallon tank (temp 72)

I have a slight hydra problem but I'm not sure how because I barely feed this tank

Stocking: 12 raccoon tiger shrimp (2 pregnant and possibly shrimplets) 2 baby mystery snails 1 large adult 3 Otto cats Bladder snails 1 assassin snail 3 nerite snails 1 anoma shrimp (i know I spelled it wrong but idk)

Plants: Anubis 2 crypts Water sprites Hornwort Christmas moss/java moss Red root floaters Duckweed Pothos Spider plants Amazon frog bit Java ferns

I've tried removing by hand but I can't access ALL my tank due to it being very thickly planted and alot' of driftwood in the back: (

I spot treat hydra with excel, in a syringe. They curl up & die immediately. Make sure not to overdose your tanks though.
