⚠️ Caution

Mollies and Cory Catfish are generally compatible as peaceful community fish with overlapping water parameter needs. The primary caution is due to Mollies' preference for slightly harder, more alkaline water and their potential to be mildly boisterous, which can stress shy Corydoras. Both species require clean, well-maintained water.

Potential Issues

  • •Cory Catfish are sensitive to poor water quality and sharp substrate; use fine sand to protect their delicate barbels.
  • •Some larger Molly varieties may outcompete Corydoras for food; ensure sinking pellets reach the bottom.
