What are some differences from freshwater fish that effect the health of tropical marine fish in captivity?
|
- marine reef fish not adapted to withstand poor water conditions of captivity
- most are wild caught: have to acclimate to confines - highly territorial - often carry latent infections, which recrudesce under captive conditions - many have specialized diets: many can’t adapt to standard aquarium feeds & starve to death in captivity - all of these factors --> ↑ susceptibility to dz |
