My new panda platy population has experienced some ups and downs in the last couple of weeks.
First - 2 of the 3 males in the other tank were showing symptoms of fin rot, so I treated them (successfully so far) with some Maracyn 2.
The male in the photos is, unfortunately, no longer with us. He went downhill really quickly and was gone shortly after I moved him to the medicated tank.
Thankfully I had 3 backup males, so I selected the smallest of the remaining males who was closest to the single female in size and transferred him to the female's tank.
One of the 2 remaining males in the other tank sustained some sort of internal injury. This could have been accidentally inflicted by me during tank maintenance, I suppose, but I didn't notice it if that was the case. He's been sinking tail-down like he has a swim bladder problem and he seems unable to use his tail fin. He also had a bright red spot along his spine toward the tail which is why I think it was trauma. Despite all this he's still perky, still eating, still swimming up to the front of the tank to say hi, and seems to have improved noticeably over the last few days. The red spot is gone now and he seems to be getting some of his attitude control back. I have high hopes!
Neither of those 2 males are showing fin-rot symptoms anymore, so that's a big plus.
The best news is that the female is still quite healthy and dumped a ton of fry in my heavily planted 20g over Saturday night. I've fished about 15 panda platy fry out of the 20g and transferred them to my snail / fry tank since then. I haven't noticed any attrits after the transfer; so far so good! :cheers:
I'll try to get some more photos soon, including some of my 3 healthy and thriving sunburst platy fry. They're growing super fast... I'm going to be up to my ears in platies faster than I expected.
