Great idea for a poll, we look forward to learning from everyone's experiences
Personally I do not believe in using any medications for non-symptomatic concerns, primarily because of the possibility of building immune resistance to antibiotics particularly. In short, if it ain't broke... don't fix it, because if you do... you may not be able to fix it as successfully should it actually break in the future.. LOL.
Any thoughts on this approach?
I think Heather is right in a purist experienced perspective. Immunity is built up toward medicine in many many ways and throughout the years it has been proven over through many different ways.
The problem as I have seen and experienced is that there are quite a few situations in which the quality of fish go downhill in a bag over a period of time.
Examples are;
Bagged fish that are triple bagged, bag buddies and oxygen in bag but the fish were fed right up to the time of bagging = poor water quality very quickly
Bagged fish that have bad water to begin with = poor water quality
Single Bagged fish = Possible punctured bag, leaky bag, water drained out
Bagged fish that have many fish in it = poor water quality
There are so many variables in the quality of the fish and until you get to know the person shipping, it almost becomes mandatory to do the following.
#1 Quarantine the fish in a tank for minimum 3 weeks to 5 weeks
#2 When the fish arrive, smell the water in the bag, look to see how much detritus (poop and other stuff), look at the condition of the fish -- If water smells foul, lots of poop, fish breathing hard and looking uncomfortable.
((for above situation, use drip method into the bag (s) and when water temperature is similar to tank and bag is filled mostly with tank water, gently net the fish out into the tank. Do not use add the bag water))
#3 When the fish are in the quarantine tank, Cover tank with blanket, make sure no light can get through, DO NOT FEED!! Cover tank for 24 hours, Do check to make sure fish are not dying or in stress
#4 After 24 hours, uncover and add light and see how the fish behavior looks. Active, curious fish with some caution is normal but still swimming and checking out their new home should be the best clue that your fish are doing well.
#5 After watching.... Feed just so very little that some fish may not even get to eat. What you want to see is no spitting out, a somewhat aggressive approach to finding food.
#6 If the fish are doing well and you gradually increase the feeding and things continue to look good.... GREAT...
No medication needed!!!!!!!!!!!!
Going back to #2
If the bag stinks, poop all over, fish lethargic, white stringy poop, many fish in the bag, bag deflated...
You drip into the bag, gently net the fish out and observe... and over the course of a couple of hours... just have that gut feeling that the fish are REALLY stressed and not doing well.
#1 Do consider adding metro... should be twice per day as it has a short medicating effect
#2 Do not FEED, KEEP TANK COVERED FROM LIGHT
#3 Check several times per day just observe...
Heather is right... its not a blanket invitation to medicate... but with good observation.... you can know the difference when and when not to...
My two bits and am sorry it's long
