why aren't the fishes swimming?
 
the silver dollars, epecially. they just idle at the far corner of the tank :(

they're pretty boring.... but when they do dart across the tank it's pretty cool. any reason why they aren't swimming around?

is your tank cycled? what are the exact params (ammonia,nitrite,nitrate?)
how often do you do water changes and how much?
how long have you had the tank set up and how long have you had the fish?
whats the temp. of the tank?


the more specific you are then most likely the more specific the answers will be

Tank is cycled..
All parameters are in order
Tank has been set up for many years, but 2 days ago new fishes were purchased at the pet store (2x Oscars, 6x Silver Dollars, 2x Pictus catfishes in 125 US gallons). Previously I've had 2 full grown Oscars and 5 other smaller varieties of Cichlids and Pleco but they all died due to power outage.
temperature is ~80 degrees Fahrenheit

i doubt the tank params are in order when adding such a big bioload at once in one day.
could you post specific readings please?

Yep...adding all of those fish at once likely caused an ammonia spike. How long was the tank empty after your other fish died? If it's been empty for a while, there aren't likely enough (or any) bacteria to support all of the waste being produced by your new fish.

Also, what kind of decor do you have in the tank? Having lots of cover with driftwood, rocks and artificial plants will make your fish feel more secure in their surroundings.

The nitrifying bacteria can survive for a time with no food source, they won't survive drying out though. How long had your tank been empty?

I have two silver dollars and my tank is in order. If your question is about that specific fish I am learning that the silver dollar fish is a very nervous fish. Mine hide and chill often coming out to cruise my tank only after no one has been over by it for a bit.

Everyone always wants your exact tank parameters and avoid answering your question. I am novice but I can read and I have eyes and I have silver dollars!

What they are telling you about adding too many fish at once is a stressful deal for a tank but if you keep a close eye on your tank parameters, especially ammonia levels, most fish will be fine through it. Just do daily checks for a while and if you notice any spike in ammonia, go ahead and do a 25% water change.

Merry Christmas!

We're "avoiding answering the question" because it's impossible to know why a fish isn't behaving normally without a better background about the tank.

Silver dollars hiding in the corner signals to me: 1) not big enough of a group of silver dollars, 2) not enough decor in the tank for them to feel comfortable, 3) some other fish is scaring the living daylights out of them and keeping them hiding, 4) they've only recently been added and will take a few days to adjust or 5) the fish are sick or suffering from water quality issues, so they are huddling in the corner for extra security.

It could be any one or a combination of those factors, so any sort of background helps. As I suggested before: if the tank sat empty for any length of time, bacterial colonies might have died off. Adding all of those fish at once to a tank that has become uncycled very likely caused an ammonia spike.

kyfishman, you should add more to your group as it will definitely cut back on some of that nervous behavior. Schooling fish always feel safety in numbers.

I'm with batman and others. The questions asked here are in an effort to eliminate or identify possible enviornmental issues that may or may noy be affecting the fish. Those who post and declare their water parameters as fine, good, normal,in order,same as always doesn't tell us diddly. It is very difficult to help anyone on a forum without all the information one can provide. Considering that 90 percent of fish illnesses are directly related to water quality or a lack thereof It becomes important . The fish could have been sick from the start. By eliminating poor water quality it becomes only a LITTLE easier to help. Merry christmas.:|
