Mudskipper Welfare: The Fish That Left the Water

Mudskippers are fish that spend much of their time out of water on intertidal mudflats. Their welfare in captivity requires careful replication of their complex amphibious lifestyle.

Key Facts

Mudskippers breathe through their skin and the lining of their mouth cavity as well as through small gills
They can climb mangrove roots and trees using their pectoral fins as crutches
Mudskippers establish and defend territories on mudflats using elaborate visual displays
They are occasionally kept in specialised paludarium setups that include both land and water areas
Mangrove destruction across Asia is eliminating mudskipper habitat at regional scale

Welfare Considerations

Mudskipper welfare in captivity requires both water and land areas — they cannot survive in fully aquatic tanks where they cannot emerge to breathe through their skin. Incorrect humidity prevents cutaneous respiration. Their territorial behaviour requires adequate space and visual barriers to prevent chronic aggression stress. In the wild, mangrove destruction eliminates their complex intertidal habitat, removing the structural complexity they need for territory establishment and breeding. Mangrove conservation is therefore the most impactful welfare intervention for wild mudskippers.

What You Can Do

Support mangrove forest conservation in Southeast Asia and West Africa
If keeping mudskippers, provide appropriate paludarium conditions with land and water access
Research mudskipper care requirements thoroughly before acquiring these specialist fish
Contribute mudskipper sighting data to citizen science platforms to monitor wild population trends
