Guppy Size Question

[Serenity]

Bought 2 smaller guppys the other day have kept them in a breeding tank till they grow a little as I had one of similar size not to long ago that my dwarf gourami ate question is how big do they need to be till I can release them in my tank at the moment they are the same size as a neon tetra

Tank has 6 danios, 4 guppies, 10 neon tetras, 1 dwarf gourami, 4 sterba corys and 6 neon rainbowfish

Only way to tell is to test it. Are you positive the Dwarf ate the other?
Imo it's more likely it just died on it's own, THEN got eaten.

it seemed fine it liked to play in my floating plants same place as my gourami who seems to chase anything that comes near them could have just died though and the other fish gobbled him up
