BMBLSAD Posted May 7, 2021 Share Posted May 7, 2021 Hey all I picked up 6 Sterbai corydoras about 10 days ago. They're my first corys, so I'm learning. The first couple of days they were all over in the water column. Such fun to watch. But over the last 4 or 5 days, they aren't as active. I have 1 in particular that I'm concerned about. He appears to have white stuff on his mouth. I've read Cory's can bruise their barbels or experience barbel erosion, but I'm uncertain if that's what I'm seeing. Most articles/posts don't have pics so it's hard to tell. He's also breathing a bit harder than the others. I'll post a few pics. I have a video of his breathing but can't post it. I just quarantined him to a 5g (cycled). He's alone and very unhappy. Do I keep him quarantined and treat him? Put him back and treat the whole tank? I have API General Cure, Erythromycin, Fin & Body Cure, & Furan-2; Seachem Kanaplex & Metroplex; Jungle Fungus Clear; and PraziPro. Water Parameters: API master test kit pH: 8.2 Nitrates: 30 Hardness: 9 degrees or 161ppm Nitrite: 0 Ammonia: 0 KH/Buffer: 16 degrees or greater than 214.8ppm Water Temperature: 76 Tank: 29g, planted, black diamond sand substrate, running for about 2 years. I do weekly 30% water changes, vac the sand, clean the filters routinely, etc. Tank mates: 2 guppies, 5 harlequin rasboras, 3 amano shrimp (new addition), 1 BN pleco, 1 mystery snail, 1 nerite snail Feeding: tank mates get a mix of floating/slow sinking stuff (like Fluval Bug Bites Betta Formula). While they're busy eating, I drop Fluval Bug Bites bottom feeder formula to the bottom for the corys. I also drop bug bites for plecos, and routinely hang spinach, zuchinni, and algea sheets in the tank for the pleco and snails. Link to comment Share on other sites More sharing options...
