Just wondering if it would be a bad idea to add a new 6inch Oscar in with my current 10inch+ Oscar????
My O lives in a 4 foot 350 liter tank with a ghost knife, featherfin catfish, bristlenose and a red tail shark.

Over the weekend i will be setting up my new 6foot 540 liter tank and transfering my fish to the new tank. I will be using my current filter and as much existing tank water as possible so i dont have to wait for it to cycle.

I was in my LFS today and noticed the had a juvenile oscar about 6inches. I used to have 2 oscars, they gew up together but when they reached puberty they started to fight really bad so i had to get rid of one, that was about 2 or 3 months ago. I kept the most aggressive one who was winning the fight and i'm guessing they were both boys due to the fighting.

Do u think it would be a good idea to try add a new oscar? My guess is its a 50/50 chance that the new one is female and the will get on.

I was thinking i could pick up the new guy the morning i plan to change tanks and add him to the tank first the add my old oscar after the new guy has settled in a bit?

Whilst the tank change over is happening my fish will be in buckets and plastic containers with air stones, dont think i will need heaters in with them while this is happening because i liven in anpartment and is alway warm inside.

What to you guys think....i was planning on doing this tommorrow or Sunday....short notice i know

You could always try it however the fact that your current oscar bullied the one that you had previously, idk if it will work. Especially due to the fact that the one that you will be puchasing is so much smaller. You should look for a thread that one of the members on here had been updating, i think that it was pepe. He was looking for a mate for his male oscar so he worked out a deal with his lfs to help him find one. He took home an oscar hoping that it was female, but if it wasnt he would be allowed to take it back to the lfs with no problem.

Thanks for the quick reply

and yes i have been following the mentioned thread.

Lets see what the others have to say

Cheers!

hey, you will have enough space for another oscar for sure. obviously no guartees they will get on etc etc. when u change in2 yr new tank adding nother fish to the tank will mean there are no pre-established terrtories and thus will have less chance of being bullied by the larger oscar. so if i was you i would do it like that

Thanks askhammatt. Do u think i should do it onthe day i change tanks or would i have a few days up my sleeve?

to make it practical, you could add equivalent or a little less fresh water in it as if you had just change your water.

this would be the most appropriate time to reintroduce new tankmate. your big o will also feel the new environment.

having the same tank water in the bucket, 2 to 3 hours with out heater won't harm your fish.

Thanks fro the respose Paul!
At the moment i am thinking to do the move today then pick up the new one tommorrow. Or should i get the new one into the tank first?

it is better to put them simultaneously or the new one should
be in first so that he would not be intimidated. putting the old
one first would give him territorial dominance against new comer.

going to get the new O right now!

Wish me luck

cross your finger and good luck

When i got to the shop the has a white tiger and he was a bit bigger so i got him, Colours not the best but with the right food i think he will colour up nicley. fish are in buckets at the moment, all the old fish are fine but the new seems a little stressed and is lying on its side.
