Keep a breeding colony separate if protecting young is the main goal.

Why guppy compatibility matters

Guppies may investigate small animals and food, so a mixed tank can affect shrimplet survival and feeding routines. In a shrimp-focused aquarium, the choice should also support steady routines, visible livestock, and access for basic care.

Before you act, check whether the fish can reach the shrimp and how dense the shelter is. Compare the item with the rest of the setup and note any recent change that could affect what you are seeing.

A careful way to proceed

review species-specific guidance and start with a contingency plan. Make one adjustment at a time and watch how the aquarium responds during normal observation.

Avoid choosing a fish only by its adult size or bright color. Labels, products, and tank conditions differ, so use a reliable guide as context and record what you directly observe. If uncertainty remains, ask an experienced shrimp keeper before making a consequential change.
