You said your tank is planted, by chance, do you use co2? Could be that oxygen levels are low.

From my experiences, fish tend to huddle at the top because of high levels of ammonia & nitrites, or from too much co2.

Jbulmann this will be my final post in your topic please take the time to read it...

We are answering your question.. if it was temp they would huddle around the heater if there is one. The water around the filter is going to have the highest oxygen concentration which still indicates nitrite or ammonia poisoning, just because they are not dead doesnt mean they are not suffering from it. Not all fish die from high ammonia or nitrites. If your tank was fishless for a while between stockings then you have to cycle all over, if there is nothing to create ammonia there no food chain at the microscopic level, remember that nitrate is the last byproduct of that food chain ammonia is the beginning so without a beginning then all above it die.
I agree with brian1973. All responses have pointed to the same problem: possible water parameter issues.

IF the tank was fishless for a day or two before you added these current fish, the bacteria in the tank would likely have largely died off. If you have fast growing plants and they are doing well, they would keep the ammonia from harming the fish (silent cycling).

Until the ammonia, nitrite and nitrate readings are known, there is not much else anyone can do to assist.

no i have not used co2. maybe ill try that. like i also have already said, im going to test the levels again, but they were fine before i added the fish. there is capyrus and bamboo in the tank right now.

i also have bioballs, bamboo and capyrus, so the tank has stayed cycled throughout the time since i set it up a while ago. thanks though, ill get back to you with the levels when i get a chance.

MTS = MULTIPLE TANK SYNDROME

as a matter of fact I do catch my fish for the most part, I am also educated in animal biology thanks for taking the time to ask :)
multiple tank syndrome. you know mts is a real disease right? thats a little insulting to people that really have it.

btw everybody is educated in animal biology, considering we are all infact animals.

There is a chance you could just be going through a mini-cycle. You'll know for sure once you tests your levels again. From my experiences, it's easier for smaller tanks to go through them while your bacteria is trying to catch up with the additional bioload.

Have you tried a water change? They usually solve a bunch of my problems.

I loled at the MTS misunderstanding xD
thats some funny stuff.
jbulmann, take those readings like you said you were going to do, and see if you find ANY ammonia or/and nitrite. this would indicate a sort of mini cycle that your tank is going through.
IF you happen to have a lot of money to spare on this hobby, I advise you get some of this stuff:H2O-PURE Freshwater
It's from the maker of Bio-Sphira and it should work. this will add any necessary bacteria to your tank, and quickly make your tank safe again.
However if you fish are already poisoned, they may still face their fate :(
Still its a handy product to have :)

No MTS is not a real disease MS is a real disease.. if anyone would be the one insulting anyone it would be you with you retard and blind and all the other comments.

Let me remind you..you came here looking for answers, we attempted to help and you decided to get insulted and belittle others. If you are not going to take the advice given then dont ask. It is assholes like you that truly ruin these forums.
excuse me please stay off of my thread. i do not want any more comments from you. i asked a question and you repetitively keep telling me i do not know how to cycle a tank, which i have already explained to you has been cycled. and yes mts is a real disease, i do go to medical school. i do not need people telling me i do not know what i am doing, i have tested everything and i have cycled the tank, which is why i consulted this website for answers, not to be told by a jerk like you that i dont know what cycling is and that i do not know how to take care of fish. i have had fish my whole life and i have never experienced anything like this which is why i came here for help.

in that case it should just be a mini cycle man. happens from time to time when a certain amount of bacteria dies off (from w/e reason, like slight lack of ammonia/nitrite)
all you need to do is give it time, test your water, and do a water change if ammonia or nitrite levels reach .5ppm
of course keep your nitrate levels below 20-40ppm.

yes i have been doing weekly water changes and i have been using the stuff that makes tap water safe for fish when i do it. its aquasafe i think. like i said, the tank was already cycled. there were fish in it when i got the new fish and i took them out and put the mollies right in after a small water change, also the bioballs keep the bacteria in the tank.

The two of you need to STOP Jbulmann while Brian may not always come off as being the nice guy, he is not completely wrong. You are asking questions that a lot of us have seen and MANY times the solution is in a misunderstanding of tank chemistry. You cannot tell someone not to respond to your thread, just like you can't demand us tell you what you want to hear. If you ask for help with a problem you need to listen and respond accordingly and ignore posts that you don't like...or use the report button.

once again, mini cycle. it'll pass. It can still happen to an established tank rarely. have you experienced this before when adding fish? you mentioned no, so thus i say it shouldnt happen often, but can.
just keep testin water to make sure its safe for the fish. make sure the temp of the water youre changing out is similar to the regular temp of the tank. that way theres no temp shock.
The bio balls do grow the bacteria, but a lack of ammonia/nitrite would still diminish their numbers.
Just wait this one out. I hope your mollies will do better soon.

Aah, then it's probably just a mini-cycle. Your mollies are more-than-likely producing more waste than the fish that were previously in there and your bacteria just need to catch up. My tanks go through them all the time when I add new fish.

alright, well he is making fun of a very serious and life threatening disease while insulting me. and calling me an a**hole. so i think it is him you need to tell to stop. i have also not DEMANDED anything from this site, i simply asked a question. and i do understand you are like the forum owner or whatever, but its not me causing the problems. i came here to get help, and while most people are helping, brian is just constantly insulting me and not helping at all. thank you.

the ick meds that you used might have killed off some bacteria...I think regardless of the cause you should probably treat it as a re-cycle, no changing or rinsing of the filter media, water changes when necessary (ammonia over 1, nitrites over .5 or so, nitrates over 20). Fish can also huddle for reasons you mentioned like too low of a temp, lack of oxygen, or some fish just like to hang out at the top of the tank :) Keep an eye on them...did I miss it or did anyone ask if the fish are eating well?
