Silversides???

[ConcinusMan]

San Fransisco Brand - Sally's silversides... SAFE (sold as fish food)
Ocean Nutrition silversides... SAFE (also sold as fish food)

Both are usually available at petco or petsmart.

We used to have Petsmarts here, but they've been gone a while now
Can't find either of those brands available anywhere.

Will try worms again, but I'll order some since my back garden is frozen like rock

I was googling my local area for fish farms today. Will be investigating prices on rainbow or brown trout fry of an acceptable size.

I'll be checking for potential bombs like water-treatment feed etc too
