Hey guys got sum newbies free for my tank as my local pet shop had sum fish handed in so now in my 598gal
are as follow




OLDS FISH
6 Oscar Cichlids (2 breeding pairs)
1 Flowerhorn
3 Jack Dempseys
1 Tigershovel Nose Catfish
3 Sailfin plcos (common)
2 Jaguar Cichlids


NEW FISH
1 15"Silver arrowa
3 12"Silver/Bala sharks
1 18"clown knife
2 6"male convicts(now own the tank)
1 14" frontosa

lucky for me she is a family friend as well as her not having the space
is the tank now overstocked or ok as it looks just inuff to fill it rather than it looking bare as hell

They all sound like appropriate additions, apart maybe from the Aro.

Google tells me that these grow up to 4 feet long, and need a tank at least 2 times, ideally 3 times their length. Your tank may just about fulfil this. My worry is for your other fish.
Arowana, depending, on their temperament, can be pretty tough on their tankmates. Once it puts on a bit more length I could see it potentially taking lumps of fin out of your larger fish. It could become a bit of a menace. In contrast, it could be OK. Need to keep an eye on it.
