Secret of reducing aggression

[shaohui75]

Just want to share my experience, i find that if you first keep your new fish in a beta box within the main tank, it will greatly reduce any aggression when it is release to the main tank. The new fish must be in the beta box for at least 3weeks to 1month. When the other fish get use to seeing the new fish, they will less likely attack it later. Also, without having to fight for food, the chances of survival is higher. I manage to introduce several angels and tangs successfully this way.

The key to this hobby is patience.

Below is a picture of it.

if the fish is too big,it will be v stress.

Hmmm..... It does seem ideal, But like reddevil said, if the fish is too big, it might get stressed. I have tried finding very large betta boxes, but cant. They seem to only come in some standard sizes. How to add in lets say, a fully grown emperor angel? O.o

Maybe i can try this. i want to add another dwarf angel to my current tank. I heard more than one dwarf angel = fight right? Currently have one coral beauty. Maybe i will try this method =)

i got a similar method that also works

put the new fish into the betta box, u will start to see which is the fish that will want to challenge the new fish

depending on what type of betta box u have ,

mine has side sliding doors , so i open the door and the agressor will swim in then tadah, new fish goes into tank, agressor stuck in betta box for 2 days, after that once u release the agressor it will no longer be agressive

OO cool method. Sad, my betta box is those with a lid on the top...-.-

Plan carefully b4 u setup ur tank, best to introduce smaller fishes in the first stage then come to the biger one... If is a fowlr setup then jus off ur lighting for a few days when u introduce new fishes, this will slow down their activities n gives new fishes less exposure to other fishes... Well, u may still c some agression here n there, don't worries, jus away fr ur tank or else u will kanna distress also. fishes r very smart like man also, they know how to gain for survival, they know when to test on u n when they can take advantage to swim further... of course, man should know them well n help them to gain higher chance of survival. fish-talk! Jus sharing my 2cents.

Hi All Bro

As I am also keeping FOWLR, would like to share my experience as follow:

1. I do quarantine my new fishes for at least a month before introduce to my main tank. This is to ensure that the new fish is eating and also well fed before going into the "jungle". The new fish may not be able to getr food for a couple of days as it will be hiding from the old fishes.

2. I always keep the new fish in a betta box before introducing like what shaohui75 bro mentioned. As for bigger fishes, you will need to build custom betta box. I ever build a so call betta box using "egg" crate that is 12" (L) * " 8" (W) and 24" (H) for letting go my purple tang.

3. I always let go the new fish in the middle of the night when all other old fishes are "alseep". This will give the new fish a chance to get familiar with the tank.

So far, this works for me.

Thanks for dachkie bro sharing this method. Will try out for my Multi-color angel which is the next inline to be place in the main tank.

Hi LemonLemon Bro

You can have more than 1 dwarf angel in one tank. Just have be careful which to introduce first. Like Argi Angel should be the last dwarf angel to go it. I might need to catch my Argi before letting my Multi-color into the main tank :-).

Hi, my tank currently got one coral beauty already. How? still can add more dwarfs? But my tank currently maxed stocked liao. Might need to wait for one fish to die, or remove first haha. =x I'm hoping my yellow wrasse dies >.< LOL.... eh im dam bad..

[dachkie]

coral beauty can be agressive, it was attacking my new chevron tang, similar colours maybe so he thought its the same species? (thought fishes are colour blind)

anyway it was the coral beauty that kena my method, and ever since he has been guai,

i added another flame angel last nite with no issues

[Morpheous]

I like the sliding door method... :idea:

Its a good way of trapping fishes also..

If you are afraid that the fish will be stress out with a small Betta box, build your own box. If you see my picture carefully, mine was made out of a used plastic tank (secure using suction and magnetic cleaner) with drill holes. You can use any large transparent plastic container to DIY.

Another advantage of this method i find is that it train your new fish to recognise food (i only feed my fish pellet and flake). New fish tend to hide too much resulting in death due to hunger. However, in a betta box, once you feed them, they are expose to the food all the time. My new fish usually start eating on the first few days, giving it enough energy to fight whatever stress/disease it might have.

I will try to DIY a box, but i dun have a drill to drill holes. What else can i use to make holes?

For me, i use a electric drill(try to borrow one because it will be easier). Depending on what kind of box you have, if the plastic is not too tough, you can just use a pair of scissor. What some people do is to heat up a piece of metal like a paper clip and use it to melt the plastic (be careful because it can be dangerous with the heat).

You can purchase a handheld battary operated drill from Black & Decker for S$45.00. This drill help me alot in DIY stuff.
