Hikari Guppy food Japan nice and small.
But
Hikari Micro Pellets food is easily rubbed between fingers to break up. The one I have been using the most over the years, but now found the Guppy food it breaks up a little , I think the other Micro pellets break nicely, some tiny some med and regular size when you do a quick roll back and forth with thumb and forefinger while sprinkling in.
When there have been very small Boraras Brigittae aka Chili Rasboras and the other tiny fish, I have used a tiny flat end of a tooth pic or pointy if you have few fish, amount of Hikari first bites.
It is sooooo easy to over feed this food because of it being so fine. In the long past I have lost some of these tiny fish because not understanding how small their mouths really are, even when nearly grown.
Hikari is not the very finest content of ingredients, more filler than I would appreciate, maybe it is needed for their special processing, it is a good staple.
I have much less concerns with poor water quality, never ammonia spikes when fed normally and solid health of fish. I feed a large number of foods, love frozen, but expensive comparatively, freeze dried and also I try to stay away from flaked food in general mainly due to fouling of the water and messing with my parameters.
Planning to try a couple new foods next week, already spent the budget of stuff this week.
