acclimate brackish fish to salt water?

[cstamper65605]

We have had marine fish for many years but i am looking to get a monodactylus argenteus for our 240 g tank. Monos are brackish water fish and we have had success previously keeping one in a marine tank. I want to get a new mono and i am wondering how to acclimate him, as the previous one we had was already salt-water acclimated. i read that brackish water is about 1.0004 salinity, so would that be a good value to start him in? how quickly can you progress to 1.023 -1.025? Days, weeks, a month?

I drip in mollies in 3 hours from fresh and they've always been fine. Some people just toss them in with nothing more than temperature acclimation and they're fine. So yes it's a different species but I would say from 1.020, 3 hours would be more than fine.

Wow, from fresh, that is good to hear. i am glad to hear that it may not take as long as i thought to acclimate. TY

Who said it was at 1.020?

He did and then edited his post. Note to self, always quote.

Monos will easily live in salt water and they are a hard fish to kill. When the hobby started I had a few of them in brackish and then when salt started I made their tank full salt where they lived for many years. I probably just added salt over a couple of days to get it to full salt water.

I recently bought 7 Monodactylus sebae to add to my 220 gal reef tank. I was thinking about going slowly with salinity increase. So far I've gone from 0 to 1.003 in 5 days. Heard at the LFS about someone killing his M.argenteus by tossing them to quickly in his reeftank. I was wondering if this may depend on their size? Maybe juveniles are more sensitive to salinity changes. On the other hand, I may be too causious.
