We are new to the fish hobby and are learning slowly but I'm having trouble knowing when I should be concerned about disease versus what is just normal stressed fish behavior. We have 27 fish in our tank- 20 guppies (5 males, 15 females), 4 plecos, 3 platies. We started with just 3 guppies and 1 pleco and have been adding fish little by little over the last couple months. About a week ago I put 2 of my females in breeding traps, they both dropped fry, and after I released them they weren't looking so hot. They were swimming funny, hanging out near the surface, clamped fins. All other fish seemed fine so I assumed they were just stressed from the ordeal. Now just 3 days ago I added 5 guppies and 3 of those are looking stressed. They don't have clamped fins yet but are all hanging out near the surface and swimming funny. 2 of them did it immediately, the other was fine the first day and now has joined them. All other fish are fine, exhibiting normal healthy behaviors. Should I treat for something? Or just leave them be? None have died yet... I am worried medication could harm all the fry in the tank? I have 12 fry in a breeding net that are all about a week old.
