i just got a albino tiger oscar he was very active in the store and even saw him eat in front of me so i picked him took him home and set him in the water for 15 mins open the bag put in tank and he just sunk down to the bottom of the tank..i was like man he was doing good in the store and now he sinks down and looking like hes dieing.. so i check the water everything was good so i said let me get him some room mates..i got a convict and a blood parrot and a peruvian green sevrum he he started swim it was like he was happy now they all eat out of my hand and don't fight that much.. and i had him in a 30 gallon by himself.. you can try that and no hes not staying in that tank...all of them are 2" its just a grown out tank...you could try room mates..
