ok, here is my problem- about 3 weeks ago i did a salinity check on my 29 gallon tank BUT the reading was off the chart. it registered way too high! so asuming it was correct, i quickly did about a 1/3 water change to still give me the same reading, so i did about a 1/2 water change trying to lower it but i still got a reading off the charts. so i called a friend to take a look at my tank, and it turned out that my hdrometer was broken! NOW the actual reading was way too low. finally with my friend's help, we got my salinity up to par and everything back to normal BUT here is my new problem:
after this ordeal ( i have 3 fish- clownfish, striped damsel, and a blue damsel) and after my shrimp and starfish had died, my clownfish just spends all his time swimming up and down the glass! he is not rubbing or scrating against the sides or the rocks, he just swims sideways all day long. his body is perfect, not a scratch or parasite present.
my blue damsel stays at the bottom of the tank, never has she gone up once since my problem, his fins are frayed but not bad. she just stays at the bottom, doesnt hardly swim, just stays in one spot. she doesnt seem to have trouble breathing. mabey she is blind? she doesnt even come up to eat. she will only eat if you put the food infront of her (makes no attempt to swim away) also her color changes freq. she goes from her bright blue to a dark black color then back to blue!
on another note, my stripe fish is acting as normal as ever. swims and eats and seems perfectly normal. so ANY help would be aprreciated, i know this is a lot but i have never had a problem like this and no one seems to know what is wrong:( thanks a lot for any help! :)

Sorry for your losses. Chalk this up to a lesson showing the importance of a good hydrometer. How low did the salinity drop?
I suspect that your salinity was fine initially. You subsequently did hyposalinity. This would have been toxic for the invertebrates (particularly sensitive ones like starfish and shrimp) but fish can usually have the salinity drop fairly quickly with little harm.
When you raised the salinity you probably did it too fast. Fish can have the salinity drop quickly but need to have it raised slowly. They are still under some osmotic shock.
You have the option of trying to drop the salinity down ( a little) or to do nothing and just hoping they will recover. I don't have any strong feelings in the matter. Few good things happen quickly in this hobby.

I'm really sorry to hear you story!
I would continue to monitor your parameters but just wait it out. At this point you don't want to stress your fish out even further. Please keep us posted and let us know how they fair. Best wishes!

jrpage- well i am happy to say that i have not lost anything else, the only things i have lost are my coral branded shrip and my serpant star. my blue fish is still staying at the bottom and not moving much, but i did notice him swimming around the bottom of the rocks instead of the glass yesterday and my clown that is "stuck" to the side of the glass is begining to swim upright across the tank a few times, he does it quickly though, like he is in a hurry or trying to "teach" himself how to swim normally again, but i may have done something worse, just yesterday (Sunday) i ordered a yellow tank and some crabs for my tank, i hope this doesnt stress them.....thanx....

Swing-Arm hydrometer, right?
Nothing is more unreliable than the swing-arms. If you have them, please toss them out. Better to guess than to go by these instruments. Get yourself a quality hydrometer or, preferable, a refractometer. See the FAQ Thread for detailed info on refractometers.
