i use the mini pellets and its so funny watching the tetras and rasboras swimming around with the pellet sticking out of there mouth.makes me giggle everytime.
My platies and guppies steal the catfish pellets too and swim round with them in their mouth - generally chased by another fish that wants to nick it. Makes me laugh aswell
I'm using a crushed combination of AquaOne colour flakes and Tetra baby shrimp for my guppies and fry. Hikari algae wafers for the BN, heard not to trust anything else.
