Safe to add on to my normal colony?

These are well worth the price, being 30 for 50 instead of a dollar each. would these hurt my already-owned roaches (blaberus, with the off chance of being hybrids)?

Yeah, yours are likely hybrids, and the Amazon ones are probably hybrids, so it couldn't hurt to add them to your colony.

Should be fine unless you're worried about hybridizing a pure line (which yours likely isn't because no one has pure lines anymore).
