Hey guys, just updating...
Firslty, I've finally convinced hubby to treat with Prazi and we did it last night!! Woohoo!! :bounce:
I've also been doing some serious research - having the day off work helps! - and found a couple of things. I found out my fish had a few symptoms I hadn't even noticed as abnormal...
Doc Johnson (www.koivet.com) says split fins can actually be a secondary stress indicator of parasites, such as gill flukes.
I also discovered that the "injected fins" (red veins in the tail fins) I had asked about are a stress response. Can also be due to various things but the only thing it could be in my case is parasites or bacterial sepsis as the water tests are all good. Assuming it's flukes.
Jumping, can also be a symptoms of either poor water conditions (irritants) like high ir low pH, ammonia etc, or else it can be parasites. Once again, because water tests are god, assuming it's flukes.
Also hanging at the surface (leaning up, head to surface) can be low pH or else gill probloems - bacterial infection in gills or flukes. Once again, assume it's flukes as no outward sign of bacterial infection in the gills.
So, armed with all the info we have treated with prazi for flukes, and will see of that stops the symptoms. Id so, we've found the problem.
Thanks everyone for your help and support
