New fish introductions

[ReeferDave01]

I have main established 6 month tank that's 250g with about 20 happy fish. When I introduce new fish it's 50/50 chance they get bullied by my Niger trigger and yellow tang. Then next morning my new fish is MIA. So what's the best way to introduce new fish to established tank so the new fish survive? I have plenty of rock and caves but still have issues.

I've heard of people going lights out for a day or two let new fish settle.

An acclimation box may help. I've used my fish trap for this.

Social/acclimation box. Or remove/isolate the yellow and trigger for a while.

I like to use an acclimation box. They can be hit or miss.

http://synergyreef.com/product/acclimation-fallout-shelter-2/ is a popular one.

I use http://octoaquatics.com/the-shu/ and am very happy with it. I like that it uses magnets instead of suction cups.

My Dad has a sheet of acrylic that he'll stick in to separate new fish from trouble makers for first week or so

Another idea is get some supply from Home Depot to make a plastic screen. It's cheap and easy to make, and isn't preventing water flow.

Even a piece of eggcrate, the type they use for overhead light diffusers, can work wonders here, if your aquascaping is designed to allow a temporary divider.

A social acclimation box can be as easily sourced and inexpensive as a "Kritter Keeper", which is available at most pet shops.

In an emergency, a mirror placed against the glass at one end can help a lot, and some folks recommend setting some aquarium nets in your rockwork, handle-down and bag-up.
