Silver datnoid in brackish water Q

[robroy]

ever wondered why you don't see large-10"+-Silveres more often? I find they grow up to 7-8" and then the growth is painfully slow, if at all.
Maybe this is the time to up the salinity, so they thrive and grow and reach full potential.
Just my 5 cents worth...

how many here have silvers ??

Okay i think i could of answerd my own question and its yes Silver dats can go from BW to FW with out to much trouble because there actuall BW fish unlike the species of puffer i bought there

So now i'm woundering if any one can help me find info on what salinity silver dats like or are there all ready several threads on this issue and its obvious i didn't look very hard

Again, there is not one majic level. Brackish water environments are always changing. pH is also just as important as salinity levels. Use a CaCO3 gravel, such as choral to keep it buffered. I never checked specific gravity. I just added 1 Tbs per 2 gallons of water that was displaced. The water displacement value was always just estimated and never exactly the same. Point is, it just doesn't matter that much with these types of fish.

I also always wandered about max size attained being dependent upon salinity levels. I have had several green scats for years and they always seem to max out around 7 to 8 inches. But, several times I have seen very large ones around 12 to 14 inches and they were always in the saltwater section of the lfs.

the problem is no one has taken the time to resurch AT in BW everyone seams to think its fine to keep them in FW

how many people keep them in BW ?

i know i was looking for a range like low end or high end brackish conditions

Most fish benefit from at least one tsp per gallon. I would consider that low end. Keeping the pH buffered on the high end would kick that up another notch. I should mention that when the pH is higher keeping the ammonia and nitrite levels low are a must. Ammonia becomes more toxic at higher pH levels. That is probably the most important thing to monitor with these fish.

I am curiuous how much salt others use for their set-ups, possibly you can find more info. on this in the brackish forums.

Thanks for the info i wen't to another LFS that had dats in brackish water and had them labled as silver dats but i could tell tell they were different species one was a thin bar from what i can tell so i suppose if i pick up a little dat i'll need to get an ID to make sure its even a silver dat
