Take care (3)

These checks follow the reasons fish and invertebrates clash: same species or genus, similar shape, mouth size, temperament, food, burrows, tank size and the order they are added. Individual animals differ; every source agrees on that.

Pests, dips and quarantine

Few

General dip

No dip reliably kills pest eggs, so a dip lowers the risk rather than removing it. Inspect new frags with a torch after lights out, including the underside and the plug.
