Too many isopods?

Is there such a thing as too many isopods? I have 2 different types, Cubaris Murina Papaya, and Puerto Rican Spiky Pink. Each enclosure has springtails, but the species evades me rn. Would it be too many to get another type? The magic potions look cute, and the rubber ducks are adorable. I've only started keeping them in June. The Papaya population has exploded. I only started w 5 Spiky Pinks, and I got them in late July.

Should I slow down and stick w what I've got for now? What is a good rule of thumb before getting more?
