Hi y'all,
I was just doing a water change, I did 30% as opposed to 20% as I had missed last weeks water change. I was using my gravel vacume and rinsing my plastic plants off as usual when I noticed that one of my corie's had a spot of red on it's belly and was swimming part way up the glass sideways. upon closer inspection I saw that it had red (must have been blood) on its belly, between its lower fins (the ones cloest to its front) and at the base of its right fin (the same ones, closest to the front). At first I thought that I had squished him while removing or replacing a plant or rock. I went through 15 minutes of feeling bad while whatching him/her take its last breaths. I rarely give up on a fish unless i am sure! any ways I was sure that this guy was done. When I took him out I took a closer look and realized that I hadn't squished him at all! his(or her) red spot on the belly was actually what looks to be some sort of rot from the inside resulting in a hole. the red at the base of the fin hadn't broken the surface of the skin but the belly was definatly a hole. Does any one have any ideas of what may cause this? I read an article on this site about corries needing sand as the substrait? could this be a factor? I have half lps cravel and half river rock that I got from the river down the street. I boiled and tested all rock with viniger to make sure they were safe(vin first boil after) I am worried that I may have adesease in the tank so any help would be paramount.
Thanks
Peter
