Brackish Water?

[blink]

Can heosemys grandis live in brackish water tanks?

[Marnix Hoekstra]

Probably not.
Do you want to keep them in a tank with diamondbacks?

[blink]

oh no, cause my silver tip sharks (Columbian sharks) are getting skin dieasese and i found out they need a lil salt in the water as they get older, but my turtles come first

My sharks are probably gonna die soon *cry*

would it be ok if i put a small amount of salt in the water?

[Marnix Hoekstra]

A small amount of salt is okay.
I hope your sharks will make it. Good luck
