Guppy - Saltwater?

[paw-paw]

Hello!

I was reading about guppies and someone informed me (he has been breeding fish for 30 yrs) that guppies can be in marine aquariums!
Not just adding a little salt - really salt water. He also said that few people realize that. What do you think?

It spossible but must be done slowly. Black mollies can have the same thing done.

Handy for feeding to your frog/lion fish...

Probably not in the long term.

Brackish and FW fish have a different body make up. Repeated feeding of FW feeders is believed to lead to fatty deposits around the liver.

However, it is noted that guppies can survive in 150-200% strength saltwater if acclimatised correctly.

I never knew that. I had heard about the Black Molleys but not guppies. the question has to be though, why would you want to!

Would their fry be born acclimitised to saltwater?

hi
Well I wouldn't wanna do this, I just tought I could share...Cause I didn't realize that either...
well about lion fish that it shouldn't eat FW fish...Who would buy marine fish for that? I mean they are so expensive and everything... (OK - that was off topic - sorry)

Mollies and guppies can be used to feed SW preds just not indefinitely. In addition, guppies can be acclimated to full salt but it takes weeks as opposed to mollies that can practically be dropped right in.

Guppies seem to not tolerate full salt if they are heavily inbred, but apparently cross-breeding them with a wild form fixes the problem. In any case, time is a major factor when acclimating guppies, apparently. I've never tried it.

It's even harder to kill guppies than I thought. My god.

The lack of omega-3 in freshwater organisms also plays a role, and probably more lacks and other non necessities....
