Why not use this https://aquaforest.eu/en/product/garlic-oil/
It has more than just garlic.
Soak some frozen food in garlic.
If I quarantine I always soak my food in this.
For my DT I don’t use it as my fish eat everything I drop in there.
Sometimes I feed them fruit flies if I have too much hatching from my Poison Dart Frogs tanks
