Hi! So I’m a new (ish) fish keeper and I was out of town for 4 days. I had an auto feeder going for the time I was gone. My platy gave birth to fry and 6 of them made it (I didn’t notice them for awhile so a lot got eaten). I found them on May 30th 2023. So I put them into a tank I had just finished cycling (I had planned it for something else but I put the fry into the tank). Fast forward to today July 6th. When I got back from my trip the fish looked like they were missing fins, they were skinny, and just not doing well. It’s a sponge filter so I don’t think the flow is too harsh. Anything will help! The tank has Java moss and Salvinia in it currently. I’m working on getting more plants. 6 platys are in the tank.
didn’t say this earlier but they are missing their fins. One is completely missing its back fin. Idk if that is super clean in the photos. (edited)
