This is readily eaten by all my smaller community fish, eg tetras,radboras,danios,and the bigger center piece fish.
Even my really reclusive fish come out of hiding in daylight to get these
Fish adore this stuff - not much more to say...
We feed this to our various killifish... easy way to trick them into thinking they are getting bloodworms.. and you can crush it for smaller fish.
My Clown Loaches get fed around 6am in the morning before the lights come on & Hikari Vibrabites make up approx. 30% their staple diet as they find them very palatable (they are always gone by the time the lights come on) & the worm/tube shape is perfectly suited to loach mouth & throat physiology.
Even the most recent fish additions- Hara jerdoni & Aphyosemion Striatum both readily accept them, so they seem to be a very palatable food in general.
The only fish I keep that won't touch them is my pygmy corys- however they have proven to be super fussy bunch, so it isn't a great surprise.
