Hello, so I currently have 2 three stripe Cory's and 1 Julie Cory housed in a 13 gallon tank. I have been planning to move them too a 29 gallon tank but they started acting strange recently so I decided to delay that move. They are still young and have not reached their adult size. Anyway, one of the 3 stripes and the julie cory have been very lethargic lately. The Julie more then the 3 stripe. It is very strange to me because they were active one morning, swimming about as usual, and then sluggish the following night. They have been this way for a few days....I do not know what is the matter. I have noticed though that their barbels are basically stubs if not a little bigger and have begun to treat them with stress coat because I have read that it helps them grow their barbels back. Does anyone know what might be the matter? I will attach some pictures so that you can see what I'm talking about. Also, the one who is lying next the the rock near the glass looks dead but he's alive. That particular fish really surprises me because just this morning he was active and normal. I really want to help and save my little guys, any help would be appreciated, thank you. ALSO I JUST SAW THE ONE THAT I THOUGHT WAS OK KINDA RUBBING UP ON THINGS. DO THEY HAVE A PARASITE? I do not see any bloating or anything. They are not really eating their food though. I have some general cure medicine for parasites as well as some ich medicine(however they don't exhibit white dots) what do you think I should do? Ohh I'm freaking out!! The fish in the background is the one that's acting normal. The other two you will see are the ones that I am worried about. This is the one that I thought was dead when I first saw it. He is breathing though. Also they are not gasping for air or anything. This Cory was the newest addition. I got him about a week ago and he was the first to show more severe symptoms. I threw this one in so that you can see their barbels. This is also the normal fish.
