Is Malachite Green bad for piranha's? i just found this out. and are piranha scaleless? my sick piranha looks like he has scales. anyway im treating them all with polyguard it has Malachite Green in it.

they are flashing bad thats why i jumped the gun on treatment I'm not sure what it is yet. any experienced piranha keep able to guide me through this. they gills look like a white and real red. and they wont stop flashing..

Malachite Green and Formalin are the ingredients in Quick Cure if you want a cheaper version. It's a good "all around" anti-parasitic med. That seems to be the best course for right now. If no other symptoms are evident, then you won't be able to refine your choice of medications.

And yes, they have scales. If you were feeding them goldfish or other feeders, they could have ich. Ich will be very hard to see on your fish, but the meds you are using will take care of it.

so im using some parzi pro and it seems to be working, only the second day and the flashing has chilled a bit. im also feeding them metro at the same time. no white poo yet but they seem to be looking a little better but not much, but there actions are better. eating like pigs again. after this im going to use kanaplex or polyguard just to make sure they heal up nicely. one is showing color again better then all silver/pale

any special way of dosing parzi pro? just did my first medication monday.
