Update: was at the LFS today, and they had a (what i believe would be considered just a regular bichir polywampus) with just the two fish the oscar has been kinda "pokey" towards the new member of the tank.
1-Will this calm down as they adjust to each other, or should I add a third fish to calm down the dominance?
2- with the newly arriving 125, could i fit another oscar or similar w/o compromising cleanliness and safety of these fish?
3- Both currently are still babies, so I was thinking if I add my final fish, then transfer all at once to their final new home it would be like they adjusted early in life and may all get along?
4- will my aforementioned filter set up be enough if i do add said 2nd oscar?
Thanks for the help yall!
Could you show a pic of the polypterus. They had it labeled as a polywampus lol. Do you have any ornaments in the aquarium.
