Weird Zebra Danio Behaviour!

[entersandman]

First of all my water settings are fine Ammonia and Nitrite at 0 and Nitrate around the 40 mark.

All fish have been fine for ages apart from a case of whitespot a few weeks ago that i cleared up by treating quickly.

Well tonight on returning home i checked on my fish as usual and found one of my Zebra Danios just hanging near the bottom, after a few mins he would swim about like crazy for a few seconds then stop dead again at the bottom somewhere, all would be still for a bit then he'd freak out again swimming about crazily then stopping. He's been doing this for the past hour or so now and i'm really not sure what it is or if it's anyting to worry about??? I've had my Danios for 8/9 weeks and never had any issues with them until now!!!???

Any ideas folks???

Do you mean he darting around the tank.
Any little bubbles on the danio, how long did you treat the whitespot.

 

[entersandman]

Yeah darting around would describe it but just very erratic!!! I treated the whitespot with the Interpet medication giving two doses four days apart as per the instructions, i added no new fish until two weeks after the last dose. No other fish are showing any symptoms of anything i mean the Zebra danio was fine this morning!!! Really odd!!

Oh and no no bubbles that i can see on the danio, he looks no different to the others.

Might not of gotten rid of the whitespot.
Best to treat up to a week after spots have gone.
Any signs of flicking and rubbing.

 

[entersandman]

Well there was no rubbing at all and all other fish are fine, he was lifeless on the bottom of the tank this morning so i put him out of his misery and took him out All the other fish still seem fine.

Shall i add another dose of whitespot treatment??? Really don't think that's it as surely other fish would be acting weird to? but if it will help???

 

[WILDER]

No don't add the whitespot med, the whitespot might of just taken its toll on the fish bless him.
R.I.P.
