New silver arowana. Lots of questions

[charles-n-charge]

I had an arowana several months ago (I was that dumbass who put it in a little ten gallon tank lol) and I had to sell it, but since then I've done tons of research on them because I simpley fell in love with this fish. As far as research goes I know it all, but research doesn't compare to experience.
Right now it is about 8 inches long and is in a 55 gallon tank until I get the 200 set up in the next month or so. It is with a baby tiger Oscar (3"), baby clown knife (4"), and pleco (5"). All going into the 200.

My first question is what kind of growth rate am I looking at with all these? Esp the aro (aiming for a 20 incher)

Second, it's coloring is gray with red and green stripes, will these colors stay it's whole life or do they fade to silver with age?

Third, what kind of aggression am I looking at with these fish?

Fourth, I'm also wanting a tiger shovelnose cat, south American lungfish, and maybe a Florida spotted gar once the fishes sizes are appropriate, is this ok?

And finally, what other advice do you have for me with this fish? And what kind of personal experiences do you have that could be helpful to me?

Thanks

Silver aro grow 1-1.5" per month on average. Within a year it will have passed the 20" mark you're hoping for. Eventually, your going to need more then a 200g tank to house your new monster.

You will need a bigger tank to house all of those fish, arowana are pretty flexible though so your 200 will be fine for a while. But a flordia spotted gar will not make it when it gets bigger.

I don't think many arowana really get bigger than two feet in captivity. I'm pretty sure it's more of a hit and miss type thing. I'm sure some do grow to good sizes but most that I've seen are always 24"-28" max. And even a 28" can live in a 200 because of how flexible they are, but bigger is better. And I plan to get a larger tank in several years so it should be fine.

And what about the other questions?

sorry but that aint gonna happen

It's hardly a four inch difference, something that flexible would still work, just wouldn't be good for the fish and really shouldn't be done, but it is possible. I never plan on putting stress like that on my fish though.

And once again, does anyone have answers to my other questions?

Wouldn't be good for the fish and really shouldn't be done, meaning, not to be done. Whether or not its possible is irrelevant. As for everything else you asked, its all in the stickies. Read them, they're there for a reason.

Wow, you ask for experienced keepers to answer your questions yet you seem to have already developed an opinion yourself. I'm sure you and all your fish will be very happy crammed in a 200g tank

Did you not get it when I say I'm not planning on doing that and will get a bigger tank when it is needed? All I'm saying is it isn't an impossible thing to do, never said I would actually do it. I'm just tired of half the people here making things sounds worse than they really are. A 200 gallon is enough to keep a healthy arowana for about 8 years or so, plenty of time to find a bigger tank. The questions I really wanted answered are the ones you can't find through research but it seems like all the people on this site want to do is tell you all the bad things and totally ignore the real statements

not just the sizes but to keep water clean with those fish in 200 is going to require an insane amount of work and i agree people sometimes sound negative but believe me only trying to help fish. any fish should never not be able to fully straighten out in any direction so minimal depth of 30"
