Young Discus and Silver Arowana

[WarrendaFish]

About a month ago, maybe a little longer, I asked around the site about discus and aros living together. I think it would be a beautiful combo to see the 2 swimming side by side.
As of now they are doing very well in a 40 gal hex, with low top current (so the aro can utilize the whole top of the tank)and other tank mates.
Stock list of the 40 gal hex:
2 silver dollar sized blue discus
1 3" Silver aro
1 6" Dino eel
1 3" African "brown" knife
1 6" transparent knife
2 blue snails
2 prawns

The inverts are awesome to watch. There actually used to be one more, but he was a trouble maker so I fed him to my Oscar
here are the 2 video links for the new aqua scape.

Everyone is thriving, growing, and awesome to watch.
I have a 120 cycling now for the aro, discus, and more new discus.

Thank you for your time. Any questions or comments will not be overlooked.

That's OK as long as you understand that aro will quickly outgrow the 120 gal. I had one that grew from 6" to 28" in 9 months, and outgrew my 240gal. I ended up selling him to a guy with a 600gal. tank. Also understand that discus thrive in groups, not just 2 fish, unless they are a mated pair. With 2 discus, one will dominate the other, and stunt it's growth.

I do understand and have made arrangements already. A bigger tank is on hold for my arrow, and more discus are being hand picked by my guy at my LFS.
How much time do I have before a growth stunt? The 120 tall is cycling now but still needs a month before I can add fish to it.

It varies somewhat, but keep up with water changes and you should be OK until your tank cycles.

I agree, see if you tell which one is on the lower end of the ladder and try to give him extra food too.

Is that part of a hamster cage in your aquarium?

Your blue snails are Pomacea diffusa, is that correct? They will not last for a long time in high temperature. Maximum temperature is 76 degrees. Any higher will cut their lifespan severely. They live for at least 2-3 years only and this is a rather short lifespan for the snails. Increase the temperature and they will live for less than a year.

Do not get any more fish until you get the tanks sorted.
