Fish Scratching

[mostlycichlids]

I have an established 120 gallon with A JD,GT,JAG I have not added any fish for about 6 months. The PH is 7.2-7.4 and the water quality is pristine, I do 25-50% water changes weekly. The filtration is Rena xp3 and 2 penguin 350s. My question is my jd has been scratching against decor and the gravel for some time now a couple of months or so. I was watching them after my night lights came on and seen the green terror do it last night. I read this article http://www.aquariacentral.com/forums/showthread.php?t=8645

I dont think it is parasites or any of that their poop is normal they eat normal and seem to be extremely healthy the JD seems to be thriving. I have doubled up on my water conditioner to detoxify the heavy metals in my water. I am kind of stumped on why she is doing this. Can it be showing off for territory? I dont want to use meds unless I know it is parasites which I am pretty sure it is not.

Oh my Jag has laid eggs twice in two months so I know she is very healthy it almost seems like the JD is trying to intimidate the Jag but they are both female. Hope this is enough info to help me out.

that discussion on nematodes has nothing to do with your fish. i'd let the 'observable health' of your fish dictate your course of action here. if you've not added any fish recently (which might have brought parasites in with them), your fish have been and remain actively healthy, exhibit good color, are feeding and in fact are laying eggs, there's nothing obviously wrong with them. i'd definitely NOT medicate them. sometimes, fish just 'scratch'.

i'd certainly continue to observe them but until you have a more definite reason to medicate, just enjoy them.

Ok thanks I think the JD is kind of intimidated by the jag and is flashing near her to get her attention usually it works. Thanks liv2padl. I posted the wrong link it was the article you wrote http://www.aquariacentral.com/forums/showthread.php?t=86451 Ill keep an eye on it I just wanted to know if it was normal in some fish she only does it a couple of times a day and it usually causes a short chase. She also swims up and down in front of the tank almost like she is trying to get attention from someone. Thanks again.
