Tips for packaging fish

Tips for acclimating new fish

When you get new fish, it's tempting to dump them into the tank right away. But, changes in water chemistry can be lethal! There are a few factors to consider: * Changes in temperature: changes in temperature of more than a few degrees can shock and rapidly kill fish * Osmotic shock: changes in water hardness or total dissolved solids are very stressful to fish * Ammonia and pH: in the bag, CO2 build-up (from the fish breathing) has lowered the pH in the bag. This converts ammonia to the less toxic form NH4 (ammonium). When you open the bag, air rushes in and raises the pH, causing NH4 to convert to NH3. NH3 (ammonia) can cause permanent damage to a fish's gills.

With these in mind, there are a couple approaches that people use to acclimate new fish to their aquariums:

Which method is "right"? Of the two largest online fish vendors, Live Aquaria recommends scoop and dump, while Blue Zoo recommends drip acclimation. So, I suspect that for most fish, it really doesn't matter as long as you are careful and understand what kind of fish you are dealing with. If you are not sure which method to use, reach out to the seller and ask for their advice.
