fish not as they should be?

Hi all I have a 20g well planted low tech tank. All of a sudden my 8 harlequins and 5 cherry barbs dont move often or swim around as often just kind of do that kind of twitchy swimming on the spot in the water flow. Ammonia 0 ph 7.2 thats all the tests i've done the been up and running properly for months now with old media in filter. They look healthy except for this. thanks in advance

How long have your fishies been in the tank and how long have they been less active? Also, what kind of flow do you have in the tank? If there is too much flow sometimes fish will head to one side of the tank and hang out there to avoid it. Does it look like they have to work really hard to stay in one spot?

It could also be completely normal. My fish will hang out in one spot quite often.

I'll do some more test tomorrow and check back its been a couple of weeks the cherrys started and now the harlequin are doing it the past week also the flow could be a problem I upgraded to a fluval 106 from internal filter about 3 weeks back the trouble is I need flow for the plants. The shrimp and assassins seem totally fine. I just want a happy tank really but could this be it? thanks again

possibly your tank went through a cycle with the fish in, and they were harmed from the ammonia/nitrite/nitrate?

+1 to testing nitrite and nitrate, especially nitrite since it's the more toxic. it should be 0 as well or your tank isn't cycled.

This could be. When you upgraded your filter did you just completely swap them out, or did you leave both running to allow a bacteria colony to form in the new one.

I was tired and it had been a long day. A right muppet is an 'englishism' which comes from the television show. We use it to describe people who are deemed to be foolish. Not unlike kermit, miss piggy or gonzo.
Thanks again.
