I’ve never seen these before they were in the Freehold Petco, any idea what they are?

That’s what I was thinking. I’m not sure how long they were in there but one was swimming a bit erratically.

I hope they find out and get them out before they gone!!!

They can be acclimated to saltwater. Brick also Carries them. I believe they are called black fin sharks.

I disagree with this practice and seen many fish crossover to salt.
Even though it can be done; question is should it be done?

Do you think they eventually fail?

Yes, these are brackish water fish. Usually, 1 tablespoon of salt per 10g of water.

I'm not a fan of transitioning fresh/ brackish fish to salt- mollies are done all the time and do a good job on algae- some even look like flasher wrasses, and are a lot cheaper- I see the attraction for sharks- no slat water sharks that I can think of will survive in a smaller tank. I'm a purist, I like my fish to be the ones I might actually see in the ocean and on a reef

my concern is how long will they leave in salt water compared to fresh water!!

 

[MadReefer]

No clue on that but they won't thrive in my opinion.

 

[ericrodriguez]

Exactly that I thought

 

[ericrodriguez]

That’s sucks!! Those are leaving animals

Interesting video on these fish. They should be in brackish water and can grow up to 2 feet long. Definitely not a fish Petco should be selling to the average hobbyist.
