Should be okay. But in this case i guess ur bichir is already dominant. Quite hard to do it, but theres always a way. Tried having bigger fishes than ur bichir?

try to put ur bichir out for few days when introducing a new fish. make the bichir feels like a new home with new fish.

or maybe rearrange aqua when introducing.

only my 2 cents. this idea come from aimank and awansakti. me noob fishkeeper.

U gotta handle the aggression. My oscar is quite passive, sometimes timid. In fact, all of my fishes are peaceful. I can even stroke my gar with my hand. Haha

If adding new fish, add during water change. This time all fishes are kinda shocked or nervous, so they kinda stick together during cleaning. Best time so that they could do ice breaking and know each other. Lol

If one fish is too aggressive, separate temporarily in another place, another aquarium or lets say a bucket, leave it for 15 mins or so. While waiting, rescape the tank, as in changing position of ur driftwoods or stones or whatever. Then put in the fish, this resets the mindset of the fish as it thinks its in a new environment. Itll be a bit more timid.

Size too is another factor. Usually the bully is the biggest.

What i do, i research and carefully pick what fish to comm together in a tank. Other than similar water requirements, i find out their aggressiveness. Sometimes in the internet descriptions are utter bull, so i watch youtube on peoples fish. Better info as people are talking from experience. This way, I always make sure that only 1 fish is dominant, and the others are passive. And the dominant is the one that is generally known as aggressive. That way the aggression is dispersed easily as the most aggressive fish knows its dominant, it doesnt feel threatened and wont bully much.

And lets say i have a bully in my tank fighting to be dominant, what i do, ill interfere myself. Put ur hand in, or a stick and bully the fish everytime it tries to pick a fight. Works for me.

Then again, fish behaviour are not general. Different fish have their own characteristics. Just maintain the best water parameters and proper diet.

aimank very pro. clap clap.
u got open fish class? 3 am morning ha? ahha. jk jk

on serious note akhmedisonline,
my oscar is very dominant yet dominant in his own territory.
anyone who enters his territory will only be bitten. thou not dead just bite to harass i can say.

yea there is biting here and there, but so far they are living happily

Hows ur water parameters, temp, pH, hardness? Ammonia levels? That can be a factor too. And feeding period ?

pH is just nice. Temp is quite important, and nowadays not that suitable. Unless in lakes, yes, the temp is quite stable. but in our tanks, not that stable. My room is extra hot(coz direct sun la), highest water temp recorded was a whopping 32C. Imagine the room temp. Thats very bad. 26-28C max is ideal..

Hikari pellets are awesome, but then again hows the ammonia level? I feed 2-3 times a week, 4 times at most coz i dont have good biomedias. 

Not to scare you la, just to rule out everything else, then can focus back on aggression.. 

Its not the canister, its the biomedia. Haha. So what kind of biomedia u use, and how many, and whats the capacity of the canister? As in how many liter per hour? People usually measure with the ammonia produced from feeding. Quite interesting process to go through!

I have a gar, an oscar, a channa aurantimaculata, and 2 endli bichirs.. Feed them tilapia feeders, sometimes hikari sinking pellets for the bichirs, and crickets/mealworms for channa.. Using sump filter..

no, ur endli cant handle ur tank. maybe time for bigger tank? lol 

I used to own auranti.... But they cannot survive long in our hot weather... Their color fade away... They live in cold water... Do u own one?...

no that's not me. that's ayum_med.

i only have 3 footer with 1 oscar. 1 senegalus, 1 albino sen, 1 delhezi, 1 shortbody delhezi and 1 indo tiger.
boring old 3 footer. ahha

Plus, bichirs, gars can starve for few months, arowana amd tigers can starve for 1 month... So u can imagine how much energy they consume... Very little..
