OT-Freshwater fish turning into saltwater fish?

preculafreak06 · 04/11/2007, 06:33 PM

Can that happen and if it can what fish will do it?

There some. Usually brackish water fish. Some will have signi***antly shorter life spans.

Guppies and mollies are quite easily converted. I'm planning on using guppies and mollies because they breed like mad. I'm going to set up a small breeder tank with a rubbermaid grow out tank for feeders So I can drop a bunch in and leave for the weekend.

You can add a small ammount of salt water every 20 min or so, or drip acclimate over 8 hours or more.

Why are you looking into this anyway?

You can acclimate a molly in about 4-6 hours, although 8 would probably be better. Guppies are alittle more questionable, some will acclimate just fine, others may not. Altough some will acclimate and even breed just fine in saltwater. I hear more success stories with molleys though and I've housed many o' molly's in my various SW setups. Not all brackish fish will acclimate to full saltwater though, so don't think just because it's brackish that it will.

did mine in less then 2 hours (Molly and Green Scat)...and Scats will breed in marine tanks...

Not all will be happy in a full marine tank, so do some research...

I was just seeing if you could do that.

Figure eight puffers have no problem, I kept one for 12 years in salt water.
