I agree, a captive bred fish is normally very much used to all kinds of prepared foods.
This also shows the benefit of QT
. Besides the obvious of protecting your display against disease, in this case you would also have a separate environment where you could make sure the fish was eating and healthy before you added it to the tank. If things went well in QT
and then went downhill when added to the tank, you have your answer that there is obviously an environmental problem with your display.
Don't assume that since the clownfish are alive at the LFS
for a week is healthy, many fish can go weeks with ailments before they finally succumb to the stress and die quickly. Internal parasites, etc. can fester for a while with a fish that looks o.k
. on the outside. If nothing else, ask at the LFS
for proof that the fish is eating (and then still 100% QT
). Finally, if getting more wild caught fish, I would buy frozen meaty foods which will be more natural over flake, and don't bother with lettuce even for herbivores (tangs, etc.) as it does not have much useful content for marine fish.
