1 silver arowanna and 1 red belly piranha
In the 75 ? Nah. You'd be starting the aro small yes ? The piranha will nip it. And piranha should be kept in schools.
Arowanna grow extremely fast up to a foot and a half or so, then top out at somewhere around 3 feet in most adequate home tanks. The 75 won't do for it for that long.
There's a lot of material on aros on
www.monsterfishkeepers.com which you should go read. A lot of people put a 240 Gallon tank as a absolute bare minimum for one aro. A lot of people insist on a tank at least as wide as the fish is long so you are looking at a 3 foot wide tank of adequate length - 6 to 8 feet - on those specs.
The amount of people who get a specimen like this (which in my opinion is totally unsuited to the average home aquarium set up - you really need something special) intending to size up the tank and never do, resulting in an unhealthy and eventually dead fish, could not be counted.
Can I ask what your living circumstances are ? Have you space for a tank that size ? Can your building accommodate it ? Are you aware that the longest recorded lifespan for this animal in an aquarium is 40 years ? And that 20 years is not uncommon, when kept correctly. Are you happy to base all your decisions about your living arrangements to accommodate this tank for that period of time ?
Have you really thought this through ?
