2" IT Alpha Troublemaker.. need help!

[hss]

guys i have 8x 2" IT in 75gal tank with 4 silver dollar,2x 4" Florida Gar and 5"albino senegalus
i have them for 1 month.. they all seems very active until last week i just realize one of the IT just become alpha of the com.. he start chasing other IT but still in normal frequency.. the rest of the IT most of times still can swim around..

i know this alpha things is normal but today he become more and more bossy,he starts chasing the other IT that try to swim out of their DW caves and some of the IT are forced to stay in the corner of the tank.. he also make the 70% stable IT become unstable.. he keep stressing the rest IT...
this Alpha keep patrolling around 3/4 of the tank.. while the rest 7 IT is only can have 1/4 tank..
what should i do with this alpha? all IT have same size.. should i take out the alpha and put him in the blood parrot tank for some time?he's the most stable compare to the rest group.. thanks guys in advance..

Nothing you can do, datnoids will always fight no matter how many you have. Either one datnoid or let there be fighting. The little chases are nothing.

Most groups of tigers will have different growth rates over time....
Wait till the others catch up in size, then you'll have a different alpha establish it self....
Have you tried taking that piece of wood out..? See what happens.

i tried to catch the alpha move him to blood parrot tanks and after one night i move him back.. and i also rearrange the decoration.. for now still no aggresion yet.. and all of them swimming around.. hope it will stay like this.. maybe the alpha scared if he attacking like crazy again he'll be move to blood parrot tank for long time..

switching between tanks can get stressfull to him i would lock him up in a breeder box on time out (naughty fish) while the rest can settle in and have a good harty meal. is it just chasing or is it nipping too does this happen at meal time? if not then it should be fine if possible try to feed the group more or more often then him so they catch up faster

why i didn't think to lock it up in a breeder box.. geez.. it's better solution than moving him to other tank.. lol anyway.. he's back to the tank and doing fine.. there's still small aggression going on but still on the normal side.. all datz can swim around this time..

last time is more likely one man show in the tank.. while the other is forced to the corner..

I have tried one method that has worked out fine for me. I had 8 IT's in a small aquarium for beefing them up. I got two bullies out of the eight, the two took most of the food, grew much faster than the others. I did'nt have another tank to move them to, so i filled a bucket with water from the tank, took the dats out, moved the driftwood and plants around, in with the dats again. Aggressions gone for a while atleast.

ofc the fish establish their ranks again, but gives the others abit time to beef up aswell

Seems that this is what you did, and it worked. Good luck with the dats, wonderful fish!

providing enough hidingspaces for all of the fish also helps prevent abit of the aggression, but you see the fish less often.
