Hooked_on_fish Posted February 15, 2009 Report Share Posted February 15, 2009 I have noticed in my tank that all the fish appear to swim buy certain object, plants or shells and without warning slap or aggresively brush up against ththese objects with their sides or tail . Can anyone explain this behavior or why they do this. Im guessing it is territorial or mating leaving a scent or something. Quote Link to comment Share on other sites More sharing options...
werner Posted February 15, 2009 Report Share Posted February 15, 2009 This is called flashing. It's usually done in an effort to displace an irritation (often from an external parasite). Have a close look at your fish- have they got any spots or bumps? With all of them flashing, you might have an outbreak of ich or something.

Hooked_on_fish Posted February 15, 2009 Author Report Share Posted February 15, 2009 I have looked quite closly but have not seen any spot, legions or groths. Although i have never seen ich so i could be lookin at it without knowing. They appear to be healthy and active with good appetites. Does any one have pictures of or know a link to pictures of ick. (I tend to feed them before i go to bed and stare into my tank for 20 -30 mins.) they say im going crazy. LOL Quote Link to comment Share on other sites More sharing options...
bottomdweller_fan Posted February 15, 2009 Report Share Posted February 15, 2009 The problem with ich is that it can hide inside the gills so even if they have nothing on their bodies, if they are flashing a lot they can still have ich that you can't see. There are lots of good articles about ich on the web - good luck. Quote Link to comment Share on other sites More sharing options...

Hooked_on_fish Posted February 21, 2009 Author Report Share Posted February 21, 2009 how long after the 3rd treatment should they stop the flashing? Quote Link to comment Share on other sites More sharing options...
werner Posted February 22, 2009 Report Share Posted February 22, 2009 And you're still not seeing any white spots? It could also be due ammonia burning the gills. Is this by any chance a new tank setup? Quote Link to comment Share on other sites More sharing options...
Endugu Posted February 25, 2009 Report Share Posted February 25, 2009 It could be Ich or gill flukes. Consider raising the temperature about 5 degrees and treat with non-iodized salt (aquarium salt) for about a 4 weeks. If the behavior persists after such time then it is likely gill flukes and they should be treated with an appropriate medication. If you want my recommendation for the dosage of salt, let me know.

Hooked_on_fish Posted February 26, 2009 Author Report Share Posted February 26, 2009 Well it has been bout 2 weeks since we finished treating for ich with medication. As well we raised the tank temp from 78ish to 82ish when we started treatment. THey are not flashing as much but occasionally i have obsevered it. Should we i try more medication for the ich in case it didnt fully cure the first time around. Or is it safe to assume that the issue is not ich? Endugo if you have reliable information source on "gill fulkes" i would appreciate any info you could forward. As i am not formiliar with it.

Endugu Posted February 26, 2009 Report Share Posted February 26, 2009 (edited) Endugo if you have reliable information source on "gill fulkes" i would appreciate any info you could forward. As i am not formiliar with it. (still learning) I don't have an online source for you, but search Monogenetic or Monogenea flukes such as Gyrodactylus.
