marbled?
2 Corydoras paleatus I will try to be brief, but I want to give you as much info as you’ll need. My main concern is Sonny, one of our platys. I thought she was pregnant, but now fear she may be ill. Let me just back up and give you some history. I started this tank 6 weeks ago with the 2 platys. Had I found your site before I would have done a fishless cycle, but too late. Water chemistry was good for a week with no detectable ammonia or nitrite and nitrate SLOWLY rising. I carefully added 2 fish at a time over next few weeks and then did a really stupid thing. I vacuumed too much too soon and upset the biological filtration.
