"shark" problems

[midnight]

i dont like calling them "sharks" cus they are far from a "shark"
but thats another story

i got these fish for free a while back
can anyone id them both?
plus whats the max size for both?

next
the big one constantly chases the smaller one
"old owners said they did it back then to"
so i guess they have to be split up
so should i......
1 move big guy to 100g with payaras,cuda,bichirs,fl gar
2 move big guy outside to my 150g pond with big koi and misc fish "after winter if they need warmth"
3 move lil guy to 55g with neon tetras and misc fish "will he become the bully?"
4 put them both in my aro tank
5 other.....
thanks in advance

Looks like you got a Rainbow Shark and an Albino Rainbow Shark. They don't like each other for territorial purposes and they grow to about 8" They are tropical so 78F-80F would be nice for them. They are usually okay with other fish, but they may become bullies, but they usually bully fish with the same shape/look.

I'd go with "other" because they'll get eaten in a couple of those scenarios

they wont like each other or anything that looks similar like some catfish. they grow big but nt to fast so any fish that gets bigger faster and will at anything smaller will make them a snack.

I know its kinda off topic... i've never been able to understand those shark stuff
but, these fish aren't **REALLY** sharks??? if no,
Do Freshwater sharks exist???

These are not loaches.

There is no such thing as freshwater shark. It's the stupid common names which tend to be misleading.

'cause you shouldn't keep 'em with neons / cardinals or any fish with red colored fins as the 'sharks' have a tendency to bully/chase such fish. They can live for years even in a 55 gal. so just separate them and keep with robust and active, mid sized, non-red-finned fish. loaches can be a good combo. sevs, cons, ...

good luck !
