Goshfush Posted February 27 Share Posted February 27 Hello, i purchased a batch of 5 Corydoras a few weeks ago. One of them had frayed fins when I got them but I assumed it was because they were in with some barbs at the aquarium stores. The fins haven’t got worse or better but I thought they just need time to grow back. Now I’ve noticed that behind one of the fins is this like bright red “bubble” ulcer thing behind the dorsal fin. There is also some redness under one of the pectoral fins and another lil ulcer thing on the pectoral fin. The fish is also no longer active and I’m not sure if it is eating. The other Cory’s all look perfect. I put it into a small quarantine tank and put some kanaplex in but I don’t know whether it’s the right thing. I tried to give it some repashy today but so far it’s just sitting in the same spot ignoring the food. I thought maybe it is Septicemia but all the photos I have seen online I haven’t seen the bubble like ulcer thing. Can you help? Thanks so much for any ideas in advance. tank parameters (before the move to quarantine) Amm: 0 ni: 0 na: 5 GH:7 temp: 26 Link to comment Share on other sites More sharing options...
