Why is my oscar not growing..

[Ogertron3000]

Did you even read my post? I change 75 percent of the water a week.... I do a 50 percent change on my day off then a 25 percent on a work day. Equaling 75 percent a week I know a 25 percent change a week isn't close to enough especially being stocked to the max.

RealCrix220 . Does this answer your question from your arsey thread?
I don’t think the OP. Meant to be offensive based on their other replies but it could be interpreted that way, If duanes reacted badly then the thread would have turned into an argument.

Lol I think we've already moved past that moment in the thread. I was asking a question not being rude. But anyways I was curious do you guys think this is adequate filtration? I have 2 sponge filters a canister a tidal 110 and I was going to add another 110 to this tank.

if your ammonia and nitrite is 0ppm everyday, then you have enough filtration. Sponge filters are great biological filtration. I used one rated for 40 g tank and it was enough for a single 12.5 inch pike in quarantine

They are 0 definitley so maybe I am good until things change in that department thanks!

I wasnt being arsey myself or trying to make anyone look foolish, i just used it as an example in another thread of how things can escalate if people are looking for trouble, everyone was cool here.
No offense intended.

As for the filters it seems you have enough, I still think your fish has just gone through the rapid growth stage and is now slowing down.
Possibly it is genetics and it just wont grow to the max size you expect, here in oz you dont really see the true giants much anymore. This is partly down to poor care but a big part of it is generations of inbred oscars slowly deteriorating in quality with each new generation. They are still a very cool fish and one day I intend to get a small one and grow it out.

That's fair and offense here haha! I know I have definitley not given him poor conditions to live in hes been thriving even the tank boss lol. Him and the featherfin fight a lot at feeding time but thats the only aggression in the tank as of now. They are very cool I just hope he hits 10 inches someday im sure eventually it will get there could just take a lot longer than I think.

Can we get a 4 month update?
I have 2 oscars 1 blood parrot, and 1 red shouldered severum in a 200 gallon.
My tiger oscar had explosive growth for 6-8 months and is much larger than my similarly aged albino tiger oscar.
Oddly, I remember the same thing happening when I did oscar thing 20ish years ago with two tiger oscars one being albino.
These two have lived in the same tank for about 9 months now so we can rule out water changes and diet as causing the size difference.
I thought maybe the albino genes just tended to be smaller, but then read about males growing faster at a younger age than females.
I haven't seen spawning activity so I'm not completely sure about sex yet either.
I dont know but I'll try to check back and update

From my experience it's not a albino/lutino vs regular oscar type of thing. I'm pretty sure it's the individuals genetic makeup. I had a red oscar first, and then a lutino/albino oscar 2nd. The red oscar grew slower to about 10" total length in roughly 3 years and the lutino/albino was 12" in the same time frame. Same water conditions, same food, same feeding behavior.

I see... were you ever able to sex them?

Nope, I did not have them long enough to verify who could lay eggs and who could fertilize. Oscars are sexually monomorphic, meaning both sexes look the same, no breeding dress, no size difference. If it were a simple size difference, then folks would have been able to reliably figure out the sex of the oscars within the past 70 years of them being bred for the aquarium.
