My daughter recently left her betta with me. It came to Colorado from Washington state in a tall jar. We put it back into the tank. Had an accident along the way where we had to hand remove it from a sink drain. This was all 2 months ago. Since then it looked fine and acted fine until about 10 days ago when I noticed it was either growing a fungus or new fin growth. The far edges of the fins were getting longer (appeared to be) but with no color. Is that a rot? Additionally it has developed a enlargement under the "chin area" behind the front fins and gills. That was hard to see for a while but now creates the different profile. I haven't gotten a good look at it but I think it is a greyish color.
About a month ago we visited the local pet store where a gentleman told us to use a water conditioner and since we purchased a live plant to use a tiny amount of miracle grow. We had been putting 1 drop into Ratty Rex's 1 quart bowl each week. Could the miracle grow be causing the enlargement?
Our cats were drinking out of his bowl until about a month ago when we covered it. I didn't know how often to change the water so it has been totally changed out only 1 time in two months. Is this the cause of the problem? I plead ignorant.
Please help if possible, Thanks.
