silver and australian pearl arowana

[redsilver]

is it ok if i mix my silver and australian pearl arowana in a 90g tank...the silver is 21" and the aus pearl is 8"...will this mix work and is it safe?...which arowana is in danger

If any fish is in danger, it's definately the 8" aussie!

Dunno, I'd be leary of this. The tank isn't that big for a 21" fish, and he might feel cramped, and get a bit... irratable... Could be bad.
