Gannon Posted June 20, 2021 Share Posted June 20, 2021 I've noticed that my Denison barbs have been somewhat lightly scratching themselves on the sand in my 125 gallon aquarium. Thjis started the day after I added them and is continuing a couple days later. They did not do any of this in quarantine and I pre-treated them for parasites in quarantine. I know this is a symptom of flukes, but that doesn't make much sense when I've already done all this. So what could it be and what should my. course of action look like with such a huge volume of water? Thanks for any help you can offer! Link to comment Share on other sites More sharing options...
Colu Posted June 20, 2021 Share Posted June 20, 2021 (edited) Flashing can be a siqn of parasties or poor water quality frist I would test your water for ammonia and nitirtes and do a 25%water change Edited June 20, 2021 by Colu 1 Link to comment Share on other sites More sharing options...

I use RODI so im pretty obsessive about that stuff. Parasites would be the obvious cause then, but im not so sure, I treated for them in quarantine and stuff already, just seems odd.

Colu Posted June 20, 2021 Share Posted June 20, 2021 Something could have got in to your water that irritating there gills I would do I water change and see if that helps Link to comment Share on other sites More sharing options...
Mmiller2001 Posted June 20, 2021 Share Posted June 20, 2021 (edited) Flukes are, unfortunately, becoming more resistant to meds. I would follow the above advice and also be ready to treat again. I would dose PraziPro for such a large tank, if it comes to that. Edited June 20, 2021 by Mmiller2001 Link to comment Share on other sites More sharing options...

Fish commonly have a low level of parasites on them at all times, just given the nature of their aquatic habitat, but their immune system is able to keep the parasites in check. In a chronic stress situation (new environment), the immune system is weakened, allowing secondary invasions of parasites and bacteria. Link to comment Share on other sites More sharing options...

Colu Posted June 21, 2021 Share Posted June 21, 2021 You could treat the main tank with prazipro just in case its parasites Link to comment Share on other sites More sharing options...

What med or treatment would you prefer, in quarantine or not Since you cannot re-quarantine (which I prefer over any other strategy), and you don’t know the exact parasite or bacterial infection that is possibly involved, then your best option is what Aquarium Co-Op refers to as “med-trio”, a simultaneous dosing of Maracyn, Paracleanse & Ich-X (I believe this is the trio, someone correct me if I’m wrong). Make sure you have several air stones going, and it wouldn’t hurt to add a bit of salt also. I can’t stress enough, however, that if it were me, I would make every effort to get them back into a quarantine situation. And again, this is all based on your assured ness that your water parameters are in check. Edited June 21, 2021 by tonyjuliano Link to comment Share on other sites More sharing options...

Mmiller2001 Posted June 21, 2021 Share Posted June 21, 2021 Med Trio in a 125 would be ridiculous. Do yourself a favor and grab a bottle of PraziPro, you would want it on hand anyways. I would suggest getting a larger bottle, or 2 4oz bottles. 100% follow up with another round in 2 weeks if you choose to dose. Link to comment Share on other sites More sharing options...
laritheloud Posted June 21, 2021 Share Posted June 21, 2021 PraziPro is reasonable, safe, and easy to use. I personally wouldn't use the med trio on a 125, and I wouldn't put them back into quarantine when you just moved them out. Just my opinion... I'd try a few rounds of PraziPro like @Mmiller2001 suggests. Are they flashing all the time? I admit I am an anxious person and can stop and watch my tanks for too many hours of the day, scrutinizing their behaviors for anything out of the ordinary. Through my searching it *looks* like a couple of odd flashes with no increased symptoms could be a whole lot of nothing, but if an entire group of fish or your entire tank starts to flash constantly, it's troublesome. Regardless, I saw flashing in a few of my fish and chose to use PraziPro on my 29 gallon display with no ill effects. Fish and invertebrates are all fine. 1 Link to comment Share on other sites More sharing options...
