I quote "The example of the worst quarantine tank would be something like a ten gallon that is setup when the aquarist brings fish home. The tank is filled with tap water, the filter turned on, and the fish are dumped in. There are no decorations so the fish are stressed. The tank receives no water changes for the duration of quarantine. Since the tank and its filter were uncycled the fish experience the typical ammonia and even nitrite spikes of a cycling tank, which stresses them further. "
1. My QT tank is always cycled with a betta.
2. There's decorations and plants in this tank.
3. For sure I do less maintenance in this tank, but I give it 100% WC for new fishs. Water quality is important for new healty fishs, especially if you want to avoid fungus.
4. You must not change the water while QTing, especially if you dose meds. (Qt last 2 weeks for me)
"The aquarist wants to see his new acquisitions and inspect for any signs of illness so provides bright lighting which also stresses the fish."
5. 10g aquariums come with a low lighting most of the time.
"All of this takes place in the matter of a week or two and then the extremely stressed fish are dumped in to the display."
6. When I dump thoses fishs to the display, they're reacclimated, except if all parameters match (especially PH and temp).
"The problem is that the display tank is much less stressful than the average quarantine tank."
7. Yes, but do you want to mess with your 100g display tank with a little sick tetra ?
"A true quarantine is at least 90 days after all signs of anything have gone away."
8. Not true, if you aim prevent the most contagious pathogens, two weeks is enough
"The fish I pick out and add directly to my display tanks never come down with anything, neither do any other fish in the tank."
9. This dude was lucky on this shot.
" Buy fish from a high quality source, provide high quality food and water, and you will rarely encounter any illnesses in any of your fish."
10. Where ? Almost all fishs from any LFS here are in tank with sick or dead mates...
