Previously we discussed that night time seems to be the best time to treat fish diseases. Is it always the case?
Certain medications (e.g. formalin) may displace oxygen from the water. In a planted aquatic system, oxygen levels should be at its peak during the day. So, when you’re treating for respiratory conditions in fish, you would choose a time of the day where dissolved oxygen would be at its highest. This time would be around noon.
Another reason for choosing to treat during the day is when you’re using new drugs in a new species. During the day, you have all the light available in order to observe the fish and how they’re reacting to the drug. So, if there are any adverse reactions, you can act on things quickly.
That’s just a snap shot on time as factor that influences management options.
