Re: This made me disgusted and furious!
this is one I have a strong opinion on, and not simply because its discus, but as far as im concerned its morally reprehensible to drug *any* animal to make it easier to handle...with few exceptions (surgery, relocating wild animals which wander into neighborhoods, et cetera) at no time should even a simple neon tetra..much less any other fish be drugged in this way, and farming operations that do this should be treated just like puppy mills are
I personally have strong feelings about bare tanks like this, but one could make an argument for it in breeding conditions..
I feel even the way of agitating the water is cruel, the way the net was swirled in the water startling the fish unnecessarily
finally, anything over a 30% water change I think is wrong- discus like their conditions to remain a constant.....what fish doesn't? theres a reason we all have our acclimation techniques....sooo either these 90% water changes are a shocking rapid change from poor quality water to good (in which case they should be making changes more frequently) _or_ if the conditions are similar enough to not shock the fish, then that large of a water change is an entirely unnecessary traumatic experience for the fish. they may survive, but I couldn't call that thriving in an environment like that
finally, these are intelligent, social beings. there is absolutely no excuse for them to ever be dumped from one location to another like a Frisbee or a piece of garbage. the best they can hope for is to get out of a sh(**y existence like that and into a tank where someone would care for their well being
