Hello everyone! I have a 60 liter freshwater aquarium with live plants and, after mistakenly purchasing a new guppy from a pet store chain and introducing it without quarantine, ended up with a pretty severe columnaris outbreak. I treated the tank with antibiotics for 5 days and haven't had anymore losses for about a month now. However, I am noticing a lot of the fry have these pin/needle point tails, and have found a few dead fry over the last few days. I was wondering, should I be worried about columnaris return or some other disease? Or is it possible that the mothers of these fry were stressed during the columnaris outbreak, leading to such deformities? I don't have a separate tank or divider for the fry, so they are currently all sharing the same space, adult and fry guppies. Any suggestions as to whether I need to take action or let nature take its course would be much appreciated! Thank you!
