I am sharing my experience. Please go easy on me.
Many people are getting a new fish ( tang ) and dealing with fish fight after QT your new fish.
I have been using this method and work for me so far.
Tank 120 gallons
Fish : Purple tang , yellow tang, sailfin tang, hippo tang
What you need?
- A new a fish case
(I will share how to DIY my fish case on next post since I need more post. LOL)
Goal:
Getting them eat together.
Explanation:
When you introduce new fish ( tang ) to new home. Let's assume your new tang is at their best performance. Ready to stand his ground and fight to die.
There are still 30% of that tang will make it in the school. Mostly will get stress and get iched then the drama happens.
Here is my method.
- A DIY fish case will allow new fish to enjoy and adjust with your water. It also help him/her to know his/her tank mate and the king of your tank.
- In case you are afraid that the fish case will stress your new fish. You gonna look for my next post of DIY fish case.
- Dimmer down your lights.
- Let new fish inside the case for at least 1 weeks. ( depend of what kind of fish)
- Start feeding the fish where the case it. Do not feed else where. The goal is make old fish to come over and eat the left over.
- Technically, you feed the new fish and then left over food will go through the case and fall down.
When will be a good time to release new fish?
- Follow the method until you see the new fish are confidently eating with the king of your tank present.
- if the king comes by the case and the new fish go crazy or willing to fight back. It is not ready sign.
This method works on my purple and yellow tang. The purple still be the king but still chase my yellow bit but the chase is norm. There is no intend to kill.
Note:
This method can be applied the other around too. Put old fish to the fish case.
