Does anyone know much about Oscars? (the fish)?

Problem with an Oscar is they dont stay small. In good conditions they can be close to a foot long in 12 months, and will eat anything that they even think can fit in their mouth. It will basically take over the whole tank, and anything that it doesn't eat will probably be bullied or die from the water pollution the Oscar causes. It not so much their aggression, they are just eating machines.

Dont get me wrong, they are a great fish, but you will need to devote your whole tank to a single Oscar, they just need that much space.

It would probably get along just fine with your big pleco, but you dont really have the space for an Adult pleco and an adult Oscar.

I would suggest a smaller Sth American cichlid, maybe a Firemouth or Jewel, as they stay at a sensible size and should be OK in a semi-aggressive setup like you have there.

i'm assuming you've between the three common freshwater puffers, the verify 8, Indian Dwarf or the Fahaka. i'd be addressing your answer in accordance to that. before each thing if its a verify 8 is a brackish fish with 75-80 2° F, KH 8-15, pH 7.0-8.0 criteria. it would want to change into below pressure if housed in a tank set up for an Oscar. The Indian dwarf calls for seventy 2-80 2° F, KH 5-15, pH 7.0-8.0 As for the Fahaka I even don't have any intensive awareness of it. yet mostly, puffers are aggressive and territorial. There sharp beaks lead them to risky with different fish, I say this because there have been circumstances the position puffers were housed in great community tanks. I say great by technique of added of 60+ gallons in nicely planted settings. i in my opinion does not propose it. in spite of the undeniable fact that you'll be able to attempt, in spite of the undeniable fact that it calls for close statement on how they are interacting. A small nip by a puffer in an Oscar might want to be devastating and vise versa the Oscars mouth might want to nicely be sufficiently enormous to eat the puffer. i'd propose seperate tanks.

An oscar would fully stock your 65 gallon tank. Regardless your tank cannot hold anymore fish as it is:

-Tiger barbs should be kept in groups of at least 6.

-The iridescent shark or pangasius catfish has an adult size of about 3-4 feet. They should not be housed in the common household aquarium.

NOOOOOOOOO dont get it. I had a 65 gallon tank for my two oscars and they would kill anything else that went in there. They even made me bleed if i stuck my hand in there while they were breeding lol. The problem if that they are fine when they are small but once they get big they will eat anything that fits into their mouth.

they are about 10 bucks, i was looking into buying one today, but the pet store guy said it would not be a good idea, bc oscars eat anything smaller then them. and i have a molly in my tank.

yeah, i had an oscar once, he got gigantic. but yes, they are teritorial and aggressive fish, eating whatver they want, whenever they want. i wouldnt want to risk it, but hey, who knows, it might learn to adapt to having them there because they wouldnt be its natural food
