i got a new cory a few days ago, i don't know what type it is but its small. my tank is good because it just is. haha. but my cory has a HUGE shiny bump right under his mouth past his gills on the bottom of his body. It just showed up this morning. What is this and what can i do about it?

Did you just feed it? Was there plenty of food laying around on the bottom that it could have eaten? I'm trying to picture where the bulge is, and if it's aft of the gills, then it could just be a full stomach :)
