Ok with that out of the way i now need your help!
Last week my swordtail in my 45g tank started swimming weird he was kind of wiggleing slowly and not swimming correctly, at the same time i noticed he had a flat stomach (it was perfectly straight) and sunken from his normal look, and he just sat there on the bottom of the tank or hideing sumwere, this lasted a few days.
i immediately put him into a hospital tank (that is cycled) then unfortunately he passed away.
Over this weekend just gone 2 more platys had the exact same complications and yesturday i put them in the hospital tank and shot off to the LFS.
I spoke to someone there and they said more than likely internal parasites and gave me Sterazin i did the 1st dose yesurday, i woke up this morning to find 1 of the platys dead and the other still not good and to make it worse i have just had to hospitalise a glowlight tetra this was acting slighlty different and kind of cork screw swimming and going in big circles swimming on its side or upside down then normal again then upside down etc etc..
My tanks parameters are fine from my test kits, and tested at the LFS yesturday they said they were fine.
Temp is 78f, waterchanges everyweek between 10% and 25% fed a variety of foods including veg... gravel is vacumed when doin waterchanges.
There are no red worms from ther anus on any of them, and all other fish in my 45g seem fine but that might change (i hope not)
I have included a pic ...unfortunately it is of the poor platty that passed away today i cant get a pic of the one in tank it just turns out too dark.
The fishes stomach look a bit more sunken and flatter than this pic.
Any help would be greatly appreciated
