firstly i keep brackisk and read up alot before starting a brackish tank........
i baught some silver dats yest and was told they ONLY live in brackish water and i couldent realy be to bothered to argue so i asked what there salinity was and got the reply "1.5 i think let me just check" and he got the hydrometer out and sure enough they were kept at 1.5, when i asked what SG i was told "i dont no about sg but the reading is 1.5 salt!"
by this point i was just triying to leave asap lol
when he asked what tank they were goin in i said a 75 to which i got "75 liters thats quite a big tank i've got a 100 at home

" he then went on to tell me that they would kill everything else in the tank (columbian shark cat, monos) as they are one of the most aggressive fish you can buy.
when i got home i used my refractometer to test the water and they were in fresh

so they are now in with my other dats in fresh and havent yet killed everything they see
oh and when i asked about some panda corys labeled as somthing stupid(dwarf half albino something) he told me they have to keep them away from the shrimp as corys kill any shrimp they see(is this true or another tall tale?)
i wont be goin back there again
